Zoological Garden of Amsterdam, don. to lib., xxxiv. PROCEEDINGS or THE ACADEMY OF NATURAL SCIENCES OF PHILADELPHIA. January 3d y 1854. Mr. Lea, Vice-President, in the Chair. Letters were read : From Baron J. W. Yon Miiller, dated Brussels, Nov. 23d, 1853, transmitting the works announced this evening, and also making en- quiries respecting the feasibility of establishing a Zoological Garden in Philadelphia. From Prof. John Le Conte, of Athens, Georgia, acknowledging the receipt of his notice of election as a Correspondent. From Mr. Isaac Lea, dated Philadelphia, Dec. 30th, 1853, returning acknowledgments for his election as a Vice-President of the Academy. A paper was presented for publication in the Proceedings, entitled " On a new Entomostracan of the family Limnadidae, inhabiting the Western waters. By Charles Girard." Beferred to Drs. Leidy, Bridges and Buschenberger. A paper intended for publication in the Proceedings, entitled " On the Ancient Alluvium of the Ohio Biver and its Tributaries, by Alfred T. King, M. D.," was read and referred to Mr. Vaux, Mr. Lea, and Dr. Buschenberger. Mr. Lea exhibited to the Academy a specimen of D'Orbigny's Acostcea giia- d/casa?ia, which he owed to the kindness of that distinguished zoologist, during Mr. Lea's visit to Paris last year. This genus he reminded the members was identical with the Mulleria of Ferussac, as he formerly suggested, and was afterwards satisfied to be the case on seeing the original specimen, described by Ferussac in 1823, which is now in the fine collection of Mr. Delesert in Paris. Mr. Lea stated that although the specimen figured by D'Orbigny had quite a length of stem connecting the young portion of the shell, the Anodonta form, with the mature portion, the Ostrea form, yet this was not necessarily or uni- formly so. In the case of his own specimen this was very different. It hap- pened, as is sometimes the case with the genus Ostrea, a. dead valve was filled up by a subsequent living individual ; and on close examination, there were really dis- covered to exist two specimens of the Anodontiform age ; one on the old single valve at one end, and another on the reverse end appertaining to the living speci- men, having the epidermis on it perfect. Neither of these specimens had a stem, PROCEED. ACAD. NAT. SCI. OF PHILADELPHIA, VOL. VII., NO. I. 1 2 [January; but advanced directly from the form of the Anodonta to that of the Ostrea, leaving the young beaks directly on the edjje of the valves. Mr. Lea thought that the difference of length of the stem, or the absence of it in various specimens arose from the fact of the young individual finding sooner or later something solid to commence the soldering of the under valve to, and then to spread out the area of the valve. On motion, so much of the communication of the Baron Von Milller' as relates to the establishment of a Zoological Garden in this city was referred to the following Committee : Mr. Ord, Mr. Vaux and Dr. Bridges. January 17 th. Vice-President Bridges in the Chair. A letter was read from Capt. John H. Ritchie, U. S. N., dated Phila- delphia, Jan. 10th, 1854, accompanying the donations to the Museum acknowledged at last meeting. Also a letter from J. Pemberton Hutchinson, Esq., dated Philadel- phia, Jan. 16th, 1854, acknowledging the receipt of his notice of elec- tion as a Member. Mr. Conrad presented for publication in the Journal, a Synopsis of the Genera Parapholas and Penicilla ; which was referred to Dr. Ruschen- berger, Dr. Le Conte and Dr. J. A. Meigs. Mr. Lea exhibited a large and beautiful crystal of limpid quartz, cut into facets, which he had obtained in Italy. On leave granted, the Committee, to which was referred Baron Miiller's communication relative to the establishment of a Zoological Gar- den in this city, presented a report adverse to the same, the Committee being firmly impressed with the opinion that the project would not succeed, from " the difficulty of procuring a suitable locality, of convenient access, within the city or its precincts ; the great amount of capital required in the outset of the undertaking, and the precarious nature of the tenure, in this country, of all that depends upon popular favor." The Report was adopted, and a copy directed to be transmitted to Baron Miiller. January %4:ih. Vice-President Bridges in the Chair. Major Le Conte presented a paper, for publication in the Proceedings, entitled " Notice of American Animals formerly known, but now for- gotten or lost." Referred to Mr. Cassin, Dr. Ruschenberger and Dr. Henderson. On leave granted, Mr. Foulke, after stating that it was probable the U. S. Government would fit out shortly an Expedition for the explora- tion of Africa, suggested the appointment of a Committee to urge upon the Government the propriety of having Naturalists attached to the Expedition. Whereupon on motion the following was adopted : Resolved j That a Committee of five members be appointed, whose duty 1854.] 3 it shall be to take such steps as they may deem expedient to recommend to the Government the scientific exploration of Africa. Committee, Dr. Ruschenberger, Dr. Leidy, Mr. Lea ; Prof. Carson and Dr. Hallowell. Junuary 31 si. Vice-President Bridges in the Chair. The Committees to which were referred the following papers, severally reported in favor of their publication in the Proceedings : On a new Entomostracan, of the family LimnadidjE, inhabiting the Western waters. By Charles Girard. LIMNADELLA, n. g. Gen. Char. Eye one. Antennae subequal, provided upon their inferior side with long and plumose setae, whilst on the upper side there are short, slender and simple spines. Two elongated tape-shaped jaws. Eeet in twenty-lour pairs, provided upon their extremities and sides with slender and plumose setae, or hairs. A series of spiny processes along the posterior half of the dorsal line. Post abdominal plate very large. Nutritive system phlebenteric. Observations. This genus diners from Limnadia in being provided with one eye only, instead of two. Also by its antennae, the two pairs of which are similar in structure, whilst in Limnadia one pair is smaller than the other. The post abdominal plate and number of feet will afford other distinguishing charac- ters between Limnadella and Limnadia. From Cyzicus or Estheria it differs, first, by the structure of the shell, which in Estheria resembles that of an Area, whilst, in Limnadella, it is altogether Cyproid in its general aspect. There is a marked difference between these two types in the structure of the an- tennae, the joints of which are provided on their upper part with numerous spines in Limnadella, whilst in Cyzicus there is but one single spine at the anterior edge. The structure of the feet is likewise dissimilar, being furnished with plumose setae in Limnadella. Limnadella Kitet, n. sp. Spec. Char. Shell : elongated, subelliptical, thickest anteriorly ; twice as long as deep ; anterior, inferior, and posterior margins regularly continuous ; upper outline somewhat irregular on account of the beaks being rather promi- nent. Valves uniformly convex. Greatest depth one eight of an inch, greatest length one quarter of an inch. Specimens may occasionally attain to a larger size. Color, deep or light brown, mottled with black. Animal : antennae composed each of twelve or thirteen subequal joints. Twenty-four pairs of feet, the six posterior ones diminishing gradually away so as to render the last three rudimentary. The last of all is inserted upon the last caudal segment but one. There is a broad sub-triangular plate, terminated by two pairs of very large spines, curved upwards; the inferior pair being longer and slenderer than the up- per one. The concave margin of that plate is furnished with a series of quite small spines. On the uppermost part of the post-abdominal plate is inserted a pair of very delicate sword shaped appendages, very difficult to be observed even with a good microscope. Along the posterior half of the back there exists a series of sixteen processes, provided upon their upper and posterior sides with about five or six minute curved spines, the tip of which is bent backwards. The anterior two of these processes are but rudimentary ; the most developed occupy the middle of the series; the posterior ones again diminish gradually as they approximate the post-abdominal plate. Specimens collected at Cincinnati were sent to the Smithsonian Institution by Thomas Kite, of that city. 4 [January, On the Ancient Alluvium of the Ohio River and its Tributaries. By Alfred T. King, M. D., of Greensburgh, Pa. The Ohio River, and all its tributaries which I have examined, are bounded by an ancient alluvial deposit, rising from one to two hundred feet above the present beds of those streams, and extending from half a mile to nearly two miles in width. In the brief description which I design to give of these deposits I shall com- mence with that extensive and remarkable one at the mouth of the Beaver River. This is a beautiful and romantic stream, rising in the northern part of Beaver County, Pennsylvania. It runs nearly south, and empties into the Ohio river about thirty miles below Pittsburgh. At its mouth are two small towns, Rochester on the east and Bridgewater on the west. The town of Beaver, which is the seat of justice of Beaver county, is situated on the hill immediately above and west of Bridgewater, on an alluvial plain, two miles and a half in length, one mile, or nearly so, in width, and one hundred and thirty feet above the bed. of the Ohio, stretching along the northern shore of that river. Although wells have been sunken, in different parts of the town, 128 or 130 feet, which would be about on a level with the bed of the Ohio, still no one has penetrated through this deposite. The strong probability is, therefore, that it extends many feet beneath the present bed of the river. On the opposite side of Beaver river this deposite stretches along the Ohio, about three quarters of a mile. At both ex- tremities it is apparently transferred to the opposite side of the river, in conse- quence of the present curving of the stream, which causes the water to impinge against the base of those lofty hills which everywhere skirt the shores of this picturesque river. Seldom does the Ohio, or any of its numerous and mighty tributaries, flow through the centre of this ancient alluvium, for this deposite is seen every now and then on opposite shores. On the eastern side of Beaver river this deposite is 20 or 30 feet higher than it is at the highest point on Beaver plain, w hich would make it there about 150 or 1 60 feet, above the bed of the Ohio. At the most eastern extremity the hills are com- posed of fine sand and loam, containing fluviatile and terrestrial shells of the genera A?iodo?ita, Unio, Planorbis, Paludina, Limnea and Helix. Nearly the whole of the residue of this deposit at Rochester, Bridgewater and Beaver, is composed of nodules of argillaceous oxide of iron, and of rounded, polished river pebbles, from the size of gravel to the size' of a man's head and upwards. At the town of Rochester, the Pennsylvania and Ohio Railroad Company has made an extensive cut of about eighty feet through this mass of iron nodules and river pebbles. Here it exhibits symptoms of stratification. Commencing at the summit, there is first a thin seam, which composes the surface soil, of sandy loam, then loose pebbles, below which there is a seam of eight or ten feet of conglomerated pebbles cemented together with an oxide of iron. So- firmly bound together are these pebbles, that the workmen, when making the cut, were obliged to blast them, and I am told that they encountered much more difficulty than they ordinarily do in more solid, compact rock. Below this is a seam of ignitable bituminous coal, about one inch and a half in thickness, extending entirely through the cut, and always preserving the same relative position. Below this coal were loose pebbles again, and so on, alternately, from the summit to the base. Doubtless this tendency to stratification in alluvial, as well as in marine de- posites, may be accounted for that streams at different periods transport different materials, but the continuous seams, and vast masses of hydrate of alumina, frequently seen in alluvial bluffs, particularly in those of the Mississippi river, and the pure crystals often seen imbedded in solid sedimentary rocks, clearly indicate the existence of chemical affinity between some of the particles of sediment, in connection with mere mechanical deposition. Beaver river is a small stream, not larger than the Mohawk, but its scenery is exceedingly beautiful. Its calm and placid bosom reflects vividly like a 1854.] 5 mirror the tall mountain cliffs, and the magnificently variegated scenery of the autumnal landscape. The deep gorges and dark precipitous ravines which cut transversely the lofty hills which rise like mountains on each side, and the broad alluvial plains which bound its shores, lined for miles with beautiful towns and villas, where the sound of cheerfulness and the hum of industry are everywhere heard, render the scenery exceeding interesting and picturesque. From the mouth of this river to the town of New Brighton, a distance of about three miles, the alluvium is composed principally of pebbles, resembling those already described. Here it is about one hundred and fifty feet in depth, at the highest point, and about three quarters of a mile wide. From this point to a distance of from ten to fifteen miles above, this deposite is strewed over with immense masses of transported angular rocks, derived from the neighboring hills. These rocks are of all sizes, and, in places, very numerous, strewed about in every direction, and piled upon each other in the most irregular manner. There are several enormous piles of these quartzose rocks, or coal grit, about eight or ten miles from Rochester, lying upon the brow of a hill, which over- looks the river, and more than two hundred feet above its present bed. Some of these masses will weigh thousands of tons. There is one w r hich is probably in situ, which will measure twenty feet in height, and over one hundred feet in circumference, much shattered below, where it is grooved, rounded, and smoothed by the long continued action of running water. This rock presents a singular aspect to the observer who attempts to account for its present form, and its relative position with the river below. It is surrounded by huge but smaller masses of the same character, all exhibiting the same wearing and polishing action of running water, and piled upon each other in the wildest confusion. I descended with Dr. Barker, of Beaver, who kindly accompanied me, this precipitous hill, along a narrow and winding path to the river below. All the way we passed over and around similar piles of rocks, and for miles above this point found a similar condition of things to exist. Most of these rocks are dis- tinctly traceable to their parent hills, still higher up the stream. The enormous size of some of these transported rocks, and the unequivocal evidence of the wearing action of running water upon them, indicate that they were carried by a long continued, turbulent and impetuous stream, which had been, previous to this exhibition of its maddening fury, in a comparatively quiet and placid condition, during which time the subjacent alluvial sediment, before described, was deposited. It may be proper to mention here, that in connection with these angular masses of quartzose grit, I found, not unfrequently, syenitic, granitic, porphyritic, greenstone boulders, &c, &c, which were exceedingly hard, rounded and polished, similar to the more common quartzose pebbles. The largest which I saw connected with the angular rocks w T ould not weigh more than a few hundred pounds. But about three hundred feet above the head of little Beaver creek, a tributary of the Ohio river, and about twelve miles from the locality I am now describing, there are boulders of granite and other primary rocks lying upon the summit of a hill, which will measure thirty feet in circumference. Indeed the hills, which here contain the enormous cannel coal vein of from fourteen to eighteen feet in thickness, are strewed over with boulders of primary rocks, and the diluvial scratches and groovings are visible in places. These hills are, in some places, 300 feet high. At different points along Beaver river, and at heights of more than a hundred feet above its present bed, I observed convincing indications of the grooving, smoothing and polishing action of running water, on the solid sandstones of the adjacent hills. These workings were unquestionably produced by the river when it flowed over this alluvial plain. The same kind of markings I observed in the hills which skirt the shores of the Ohio. About fifteen miles below Pittsburgh, at a place called the Narrows, I observed, at the height of more than a hundred feet above the river, the solid sandstones polished and grooved, as if channelled by the moulding instrument of a joiner, and even pot holes are worn into their sides. 6 [January, Nearly the entire cities of Pittsburgh, Allegheny and Cincinnati are built upon this remarkable deposite. From Pittsburgh to Wilkinsburg, seven miles east, it is seen stretched along the northern shore of the Monongahela river, and nearly two miles in width. To this remarkable locality I will now briefly direct attention. Passing from Greensburgh to Pittsburgh, along the turnpike, it will be observed that the last anticlinal roll of the Allegheny chain of mountains is at Grapeville, four miles west, and the last synclinal trough, which is but imperfectly formed, is about three miles further west. From this point the beautiful undulations which are so characteristic of the Allegheny chain, die away, and the rocks assume nearly a horizontal position. Their horizontality, however, is only appa- rent, for they really rise, at an almost inappreciable angle, westward. From this point to within seven miles of Pittsburgh the general geological and topo- graphical structure of the country remains nearly the same. At the summit of the hill, which overlooks the town of Wilkinsburg, standing upon the limestone which is super-imposed upon the great Pittsburgh seam of coal, the observer beholds, more than a hundred feet beneath him, a beautiful and extensive alluvial plain, bounded on the north by hills, which separate it from the Allegheny river valley, and which contain the coal and limestone to which allusion has just been made, and on the South by the Monongahela river. The whole of this great seam of coal and the incumbent limestone, to the depth of three hundred feet, have been swept away by a process of denudation, and their places partially supplied by an alluvial deposite over one hundred feet in thickness, and about the same height over the present bed of the Monongahela river. As the Pennsylvania Railroad passes over this deposite I shall avail myself of the measurements which are given in one of the last annual reports of the Com- pany. The elevation of the Ohio river at Pittsburgh, above tide, is given at 700 feet. The elevation above tide at Wilkinsburg is 922. There would, there- fore, be a difference of tidal elevation between Pittsburgh and Wilkinsburg of 222 feet. After substracting 22 feet feet for the fall of the river between these two points, we would have 200 feet for the depth of the deposite. If we assume that the shale and limestone upon which this vast deposite re- poses, and which will be presently described, are from 200 to 300 feet beneath the Pittsburgh seam of coal, we will be enabled to form some idea of the enor mous denuding process, by which this river excavated its channel, and after- wards deposited upon its ancient bed, in some places, over two hundred feet of sedimentary matter. This is, of course, only an approximative estimate ; but from all the data which I have been enabled to procure, the average depth may be safely assumed at from one hundred to two hundred feet. In consequence of the great depth of this deposite at Wilkinsburg, I, at one time, conjectured that the Allegheny and Monongahela rivers met, at some antecedent period, and formed the Ohio, either at this point or at East Liberty, which are from five to seven miles East of their present junction. To satisfy myself on this curious point, I crossed the plain at Wilkinsburg, three quarters of a mile, to the base of those lofty hills which separate the two great alluvial valleys, and found that the whole region was composed of river pebbles, sand and loam, with which were mingled fluviatile and terrestrial shells. Near the Frankstown road, which is nearly two miles in a straight line from the Monongahela river, I saw some men excavating a well. They had gone down to the depth of twenty or thirty feet, and had passed through nothing but pure river sand and pebbles, meeting occasionally only with an Anodonta or a Unto. Near this point I crossed the dividing hills, and descended along a narrow path to the road which winds along the bank of the Allegheny river. Here I found this ancient deposite presenting: nearly the same appearances, and of about equal magnitude to the one on the Monongahela side. In the neighborhood of Laurenceville it is of great breadth, and of not less than two hundred feet in hickness. 1854.] 7 The hills which separate these Two ancient alluvial valleys are a continuous chain, and of sufficient altitude to constitute an effectual barrier to the mingling of the waters of these two rivers, at any point nearer than their present con- fluence at the city of Pittsburgh- I observed at Rochester, New Brighton, and at different points along the Monongahela and Allegheny rivers, that this deposite reposes on a dark colored shale, sometimes passing into more compact slate. As I was descending a hill on the Frankstovvn road, near East Liberty, I discovered an old acquaintance, a thin stratum of calcareous rock, on which the shale re- poses, and which in contradistinction to other limestones, belonging to the coal series I have denominated the ^rj^a-limestone. This is a somewhat peculiar rock, characterised by containing a vast number of small bivalve shells, belonging to the genus Atrypa, etc. When long exposed to the atmosphere, its external surface readily disintegrates, and presents a rag- ged and shaly appearance, the surface being covered with small Atrypa and pro- jecting joints of Encrinites. In some localities I have found in this rock the genera Terebratula, Trilobites, Plei/.rotomaria, Productus, Spirifer, Bellerophon, Euomphalus, Ammonite and Orthoceratite. But the joints of Encrinites and the small Atrypa are the charac- teristic fossils, and distinguish it from all other limestones belonging to the car- boniferous series. This limestone, in Westmoreland county, is seldom found more than two or three feet in thickness. But near the Ohio line I found it over ten feet, it being there a very compact and durable rock, well adapted for agri- cultural and other purposes. It is exposed at numerous points in Western Penn- sylvania, and uniformly presents similar lithological and paleontological cha- racters. I mentioned, at the commencement of this paper, that this ancient alluvium was traceable everywhere along the Ohio river and its tributaries which I have examined, and doubtless along those which I have not so closely surveyed. Those tributaries to which my attention has been more particularly directed, are the Beaver, Allegheny, Monongahela, Youghiogeny, Kiskeminitas, Loyalhanna and Conemaugh rivers, etc., etc. But in the brief and necessarily imperfect delinea- tion of these remarkable deposites, which I have attempted to give, I have con- fhied myself to a few localities only, leaving a more extended and minute description for some future period. It is not at all improbable that those high bluffs which bound the vast alluvial valley of the Mississippi river (which is from thirty to fifty miles in width), were deposited at the same period. Also the alluvial terraces on which the city of Cincinnati is built, the highest of which is 120 feet above the level of the Ohio river; and doubtless the natural terraces and ridizes of Lake Erie and Ontario, which were so graphically delineated by Mr. Charles Whittlesey, of Cleveland, in the July No., 1850, of the American Journal of Science. For, in all these localities, fossil teeth and other bones of the mammoth and mastodon have been found imbedded in this deposite. These animals, which were once the lords of the creation, the primates of this lower world, perished and became extinct in that last grand revolution, during which I presume these ancient sedimentary deposites were slowly and gradually elevated to their pre- sent position, and which immediately preceded the advent of man. From the whole of this investigation my mind has been convinced that the relative position of the rivers and this ancient alluvium through which they now pass, or along whose borders their waters deeply flow, has changed since the period of deposition. But when, and in what manner, or by what cause, are questions not so readily answered as proposed. The hypothesis of local oscillations, first proposed many years ago by Sir Charles Lyell, to account for the deposition of the Rhenish loess, will, with slight modifications, I believe, clearly explain all the phenomena connected with this post tertiary formation. Indeed, from the numerous facts upon which this hypothesis is based, it may be regarded as an exceedingly plausible theory, if not a legitimate induction. It has lonj; been ascertained that various parts of the earth's surface are now, and perhaps ever have been, undergoing slow and gradual oscillatory movements. 8 [January, Parts of Sweden, Norway, and the shores of the gulf of Bothnia, have been long gradually rising. Also extensive regions of South America have been undergoing a slow but gradual upheaval, during a period of many centuries. On the other hand, the gradual sinking of the coast of Greenland, for the space of more than six hundred miles, during the last 400 years, has been more incon- trovertibly established by actual markings and critical examinations made by the most astute minds. Large portions of the earth's surface have been suddenly upheaved, whilst others have as suddenly subsided. The whole coast of Chili was suddenly elevated several feet by the earth- quake of 1822, producing terrible commotion in the sea, and sending vast waves over the ocean, which doubtless transported huge masses of rocks many miles from the shore. In 1611, an earthquake sank the town of New Madrid, on the Mississippi river, several feet beneath the waters, the vibrations of which continued three months. Many other facts of an analogous character might be adduced, but these are sufficient to show that various parts of the crust of the earth are now under- going oscillations, and that it is not at all improbable that the hydrographical basin of the Ohio may have undergone, at some remote period, similar move- ments. First we may suppose that there was a gradual subsidence during a period, perhaps, of many centuries, of the whole hydrographical basins of the Ohio and Mississippi rivers, and even extending beyond che limits of their tributary streams. This depression of the land would necessarily lessen the fall of the waters into the Gulf of Mexico, and increase the alluvial deposite. After a cer- tain indefinite period we can readily suppose that this process of subsidence was reversed, and the whole as gradually upheaved, until the rocks were brought to their present altitude, when the oscillation ceased. During this slow upward movement the waters would necessarily cut their channels through the alluvial deposite, which had been thrown down during the process of subsidence. At the commencement of this upward movement we may suppose a sudden upheaval to have occurred in Beaver county, somewhat analogous to that on the coast of Chili, in 1822, which would produce such commotion and recoil of the waters in Beaver river as to cause them to impinge, with terrific force, against the projecting rocks of the adjacent hills, rive them asunder, and pile thein as they are now found, over its ancient alluvial bed. Afterwards, the process of elevation may have been as gradual as that of the shores of the Gulf of Bothnia, which amounts only to two or three feet in a century. In corroboration of this view I may mention, that although the rocks are nearly horizontal, yet the hills which skirt the shores of this beautiful stream are often seen cracked from the base to the summit, and the strata, in places, much disturbed. Also, the dark, yawning gorges, and broad and deep ravines, cutting entirely through the hills, indicate, I think, that the rocks here of the ancient coal measures have undergone great disturbance since the period of their original deposition. Notice of American Animals, formerly known, but now forgotten or lost. By John Le Co.nte. The writers of the last century have left us descriptions of several animals which modern research has not since been able to detect. In looking over the works of these authors, who favored the world with their knowledge so long ago, it necessarily happens that we find their descriptions more or less imper- fect, either from the insufficient manner in which they were made, or from that brevity of expression which was then fashionable in natural science. Hence 1854.] 9 has arisen much confusion and indecision. I have selected from these writers of a former age, the following animals which appear to have heen then well known, but are now forgotten or overlooked ; I beg leave to call the attention of natur- alists to this subject, with the hope that they may be all found and accurately described, or else struck out from the number of those enumerated among the productions of America. Felis rufa, or Bay Cat of Pennant, Arc. Zool., vol i. p. 51. With yellow irids, ears erect, tufted with black long hair; color of the head, body, and outside of the legs and thighs a bright bay, obscurely marked with dusky spots; the forehead marked with black stripes, from the head to the nose; cheeks white, varied with three or four incurvated lines of black; the under and upper lip, belly, and inside of the legs and thighs white, the inside of the upper part of the fore legs crossed with two black bars ; the tail short, upper part marked with dusky bars and near the end with one of black, the underside white; fur short and smooth ; twice the size of a common cat, (that is 27 inches long,) said to come from the interior of New York: probably erroneous. Described by Mr. Pennant from the living animal. The common wild cat of our country, found in all the northern, southern, and western states, has in latter years been confounded with this species ; I think, however, they cannot but be distinct. Mr. Pennant, the best naturalist that England has ever produced, could never have confounded two animals so dis- similar. It is true, in describing one, he had before him the living animal, in the other a dried skin, but of the last, he could examine hundreds. He certainly could not have mistaken the indistinct brownish grey of the one for bright bay, nor could the last color have faded into the other. The common wild cat, however, never should have been called Felis rufa, even if it was identical with Pennant's animal, as Ray had described it in his Synopsis Methodica Animalium, p. 169, as Catus montanus. If these two ani- mals are the same, why has the name given so long even before the birth of Pennant, been discarded, in defiance of the rule of priority in nomenclature ; when it was last described, it was easy to restore the name of montanus. A just regard for the name of Ray, if nothing else, surely demanded this. A description follows of the Felis montana, as I knew it in Georgia, made from numerous specimens either living or recently killed, including probably every variation to which the animal is liable. Felis montana. Mountain Cat, Pennant, Arc. Zool., vol. i, p. 51. Catus mon- tanus, Ray, Synops. Method. Animalium. Above, hair mixed dusky, and pale brown, top of the head brown striped lon- gitudinally with dusky, cheeks with dark brown, back with dusky ; the last sometimes wanting. Irids yellow, ears black, upright, and slightly pencilled, especially during the winter; with a broad, transverse, cinereous bar. Cheeks on each side with a large semicircular tuft of long hair. Legs spotted with dark brown, sides most frequently obscurely spotted with the same, sometimes, how- ever, not spotted; chin and throat white, with a black stripe on each side, form- ing an angle ; sometimes these stripes are wanting, or very faintly marked in pale brown. Belly, inside of the thighs, and hind part of the fore legs whitish, spotted with black. Tail, above, generally very faintly annulate with brown; these rings often disappear; tip black, beneath white, which color appears on the upper part at the tip, whenever the hair is in any way disturbed. Feet beneath dusky or dark brown. Mean length of 12 specimens 31 inches, tail 6. I have given the foregoing very full description, that it may be compared with the preceding. Most of the marks which are common to the two, belong to al- most every species of the genus Felis. I add two obscure species, of which but little is known. I am not willing to pronounce them distinct from each other or from the montana, without farther examination. The first was seen in Califor- nia by my son, and the description and measurements were made by him ; the other is extracted from Lewis and Clarke's travels. 10 [January, Californian Wild Cat : Above, mottled white, black, and fuscous, lighter on the sides, which are slightly barred; beneath, white; legs fuscous, with black bars, much more dis- tinct on the anterior ones, which are anteriorly white. Ears large, rounded, black, with a white spot connected with the mastoid part, tip with a short tuft. Tail short, blunt, barred with darker, tip black with an extreme white point. Length 31 inches, tail 6, head 4.5, height 1.5. Lewis and darkens Wild Cat : Larger than the wild cat of the United States; color of the back, neck, and sides reddish brown, irregularly varied, with small spots of dark brown, tail two inches long and nearly white, except the extremity which is black; it terminates abruptly, as if amputated. Belly white, variegated with small black spots, legs of the same color as the sides. The back is marked transversely with black stripes; ears black, on the outer side covered with short fine hair, except at the upper part, where it is furnished with a parcel of fine, straight, black hair three- fourths of an inch long. The hair of the animal is long and fine. This animal was called by Rafinesque, Felis fasciata. I have declined adopt- ing his name, as he never saw it, and was too much in the habit of describing things by hearsay, with as much confidence as if he had himself procured them, and had them lying before him. A drawing or an engraving was sufficient for him to make a new genus from, as was often the case, I am sorry to say, with authors of more credit. Both Charlevoix and Dupratz, mention a species of Felis in Louisiana, which appears not to have been lately seen ; they call it Pichoux; the following is a description of it Pichoux : Upper part of the head, neck, back, sides, shoulders, and thighs bright tawny, face striped downwards with black, shoulders and body marked with stripes and large oblong black spots, the legs with small spots, breast and inner side of the legs and thighs whitish, spotted with black ; tail long, marked with black, taw- ny, and grey. Size of a common cat, (about 18 inches). Does not appear to be the Felis pardalis, from its smaller size, and probably different markings, besides being in some of the under parts white. If this ani- mal is no longer found in Louisiana, it is highly probable that it may be met with in Texas or New Mexico. Animals at one time extremely common in any particular country, will suddenly leave it without any visible cause. As an in- stance of this : previous to the year 1820, no bird was more common in that part Georgia where I resided, than the Conurus Carolinensis or Parakeet. They would pass through the air in flocks of from 50 to 100. They suddenly all disappeared, and for more than thirty years, not one has been seen where they were so abun- dant. Travellers through Texas and New Mexico, would do well to look for this beautiful species of cat. The Chat sauvage, described by Dupratz, vol. ii., p. 93, is an animal well worth enquiring about. He thus describes it : Chat sauvage : He says that it does not feed on animal substances, but on fruits, bread, and other vegetables. It seems that it w r as easily and often tamed. It is gentle and frolicsome, and not more than 8 or 10 inches high and about 15 long. The head like that of a fox : when tamed the color is grey ; when wild, red : its paws have long toes and short claws ; it has improperly been called a cat, as it has nothing of the cat about it but its activity, and bears a greater resemblance to the marmot. 1854.] 11 Silvery Fox, of Louisiana, Penn. I. c, p. 48. With a fine and thick coat of a deep brown color, overspread with long silvery- hairs of a most elegant appearance. They differ from most other American species in their habit of burrowing. The description is borrowed from Dupratz, vol. ii., p. 92. This can hardly be the Canis velox. Pennant in Supp. to Arctic Zoology, p. 52, mentions a whitish grey fox, no larger than a hare, common among the Archithinne Indians, 4000 skins of which have been brought in one year to the British factories. The Comanche Dog : Common among the Comanche Indians. Naked, except a few stiff hairs about the mouth. This dog is mentioned by Clavigero, vol. i., p. 56, as an inhabitant of Mexico, called by the natives Holoitzuicintli. It is remarkable that though some of these dogs have been brought within the United States, we have no description of them : they are quite large, being upwards of two feet high, and used by the natives for hunting. Here is an instance of the absurdity of those writers who state, that climate has an influence in altering the appearance of animals ; thus they tell you that the so-called Turkish dog, which is hairless, has been made so by its progenitors living for numerous generations in a warm climate ; now here we see an animal equally naked, which inhabits the moun- tains and cold steppes of the south-west. Of a similar character is the assertion that sheep lose their wool in the Southern States, and in the West India Islands. The Water Rat of Pennant, 1. c, p. 130. With small eyes, ears covered with fur, teeth yellow, body covered with long black hair, mixed with a few of a rust color, belly of a deep grey. A Mouse of Louisiana : Mentioned by Dupratz. Not larger than Mus musculus, of a very bright bay. These are all the mammals which I can collect, as worthy of being called im- perfectly known, or rather lost to modern naturalists. I now proceed to consider the Birds. Vultur sacra : Bartram's Travels, p. 150. The head and neck are bare of feathers nearly down to the stomach, where the feathers begin to cover the skin, and soon become long and of a soft texture, forming a ruff or tippet, in which the bird, by contracting his neck, can hide that as well as the head ; the bare skin on the neck appears loose and wrinkled, which is of a very deep bright yellow color, intermixed with coral red as it approaches the yellow of the sides and fore part. The crown of the head is red; there are lobed lappets of a reddish orange color, which lie on the base of the upper man- dible. But what is singular is, a large portion of the stomach hangs down on the breast of the bird, in likeness of a sack or half wallet, and seems to be a dupli- cature of the craw, which is naked and of a reddish flesh color, this is partly concealed by the feathers of the breast, unless when it is loaded with food, and then it appears prominent. The plumage of the bird is generally white or cream colored, except the quill feathers of the wings and two or three rows of the co- verts, which are of a beautiful dark brown; the tail which is large and white, is tipt with this dark brown or black, the legs and feet are of a clear white ; the irids golden ; the pupil black. The tail was used by the Seminoles as a war standard. Dupratz, vol. ii., p. 109, mentions this bird under the name of White Eagle, and says that the Indians in whose neighborhood he lived, the Natchez, used the feathers for adorning their pipe of peace. Ferruginous Woodpecker : Pennant, 1. C, p. 271. With a dusky bill, the crown and pendant crest of a pale yellow ; a crimson bar extends from the mouth along the lower part of the cheek. The cheeks, 12 [January, back, and coverts of the wings are of a'deep ferruginous color, lower part of the back of a pale yellow ; primaries ferruginous, barred on their inner webs with black. Sent from South Carolina to Mr. Pennant, by Dr. Garden ; therefore there can be no doubt of its having been obtained near Charleston, although no one has ever seen it since. The high character of both these gentlemen forbids us to suppose that there was any deception on either side, either in sending the animal to Europe, or in its habitat. The Florida Pheasant : Mentioned at page 20 of Stork's introduction to John Bartram's Journal of Travels in East Florida. I have had described to me a bird, which must have been this, as inhabiting the hummocks on the banks of St. John's River, but I never had the good fortune to meet with it. Norton Sound Bustard, Penn. vol. iii., p. 321. A Captain Rich informed Mr. Pennant, that at Norton's Sound, in latitude 64 30', he had seen great flocks of a large bird which were very shy, ran very fast, and for a considerable way before they took wing, so that he could never get one shot. Black Ibis, Bartram's Travels, p. 148. Black on the upper side, breast and belly white, legs and beak as white as snow. Size of Ibis alba. Red-billed Heron, Pennant, Supp., p. 65. With a red bill. Irids yellow, legs green, plumage white. There are many of the smaller birds of America described by Pennant, that I am convinced are not now known, and many more that have lately been de- scribed as new species, that were well known to the English naturalist. Not being, however, sufficiently acquainted with the ornithology of our country, I cannot, without devoting too much time to the subject, determine which they are. It has all along been the custom with American naturalists, entirely to neglect everything that this illustrious man and elegant scholar has written on the subject of our animals; but it would be a labor well repaid by the thanks of every lover of science, if any one would go over his Arctic Zoology, and give us the scientific names of every thing which he has described. There remain only a few reptiles to be added to this list : there can be no dif- ficulty in obtaining them if they really exist, and I cannot see how any one can doubt of their existence. A very little attention on the part of persons living where they are said to be found, would soon make us acquainted with them. Trionyx, of Bartram. Travels, p. 177. They are flat and thin, two and a half feet in length, and eighteen inches in breadth across the back ; in form resembling the sea tortoise, the whole back shell except the vertebrae or ridge, which is not at all prominent, and ribs on each side, is soft and cartilaginous, and easily reduced to a jelly when boiled ; the an- terior and posterior extremities of the back shell appear to be embossed with round horny warts or tubercles ; the belly or nether shell is but small and car- tilaginous, except a narrow cross bar connecting it at each end with the back shell, which is hard and osseous ; the head is large and clubbed, of nearly an oval form, the upper mandible is however, protruded forward and truncated, somewhat resembling a swine's snout, at the extreme end of which the nostrils are placed ; on each side of the base or root of this proboscis are the eyes, which are large. The upper beak is hooked and sharp like a hawk's bill ; the lips and corners of the mouth large, tumid, wrinkled and barbed with long pointed warts which can be projected or contracted at pleasure, which gives the creature a frightful and disagreeable countenance. Inhabits St. John's river, Florida. It is a remarkable circumstance, that although this tortoise is found as it were at our very doors, no one has ever seen it since the venerable author of the pre- 1854.] 13 ceding description noticed it in his travels. There can be no doubt of its exist- ence in St. John's river of Florida, and that it can be obtained at any time. Although it is represented in the figure attached to the description with five claws on all the feet, this does not detract from the truth of the account. If this be an error, I attribute it to his not having made a complete drawing of it at the time when he first saw it, and afterwards having finished it from memory ; from this may have resulted the error, if there is one. Although I do not see any more difficulty in a Trionyx having claws on all his toes, than in a Cistudo having three claws when it has five toes j in this case there is a subtraction, in the other an addition. It has been said that this wa3 an incorrect and exaggerated figure of the Trionyx spiniferus (spinifer) of Lesueur. Nothing can be more absurd than this assertion. Lesueur's species has on the front part of the cara- pace a series of small pointed warts not easily discoverable, while Bartram's animal has larger extensible and contractile tubercles on the head and neck. I remember when it was much the custom to ridicule Mr. Bartram, and to doubt the truth of many of his relations. For my own part I must say, that having travelled in his track I have tested his accuracy, and can bear testimony to the absolute correctness of all his statements. I travelled through Florida before it was overrun by its present inhabitants, and found every thing exactly as he re- ported it to be when he was there, even to the locality of small and insignificant plants. Mr. Bartram was a man of unimpeached integrity and veracity, of primeval simplicity of manners and honesty unsuited to these times, when such virtues are not appreciated. Apalone hudsonica, Rafinesque, Annals of Nature, p. 3. Upper shell rounded-elliptical, fiat, entire, soft, with a small anterior keel, yellowish with brown spots, and a circular black line near the margin. Two long oculated spots before and behind the eyes. Nose proboscidal; jaws with- out a bill. Lower shell anterior. Body denudated behind. Tail obtuse, mu- cronate, shorter than the shell. Five palmated toes to all the feet, with small claws. Length 2 to 6 inches. Found in the Hudson river between the falls of Hadley, Glen, and Baker, and further up to the source. Called Mud Turtle. Although this description was published long ago by Rafinesque, no one, that I know of, has ever thought fit to look for the animal. Now, although Rafin- esque was certainly insane and apt to see and describe things w r hich had no real existence, yet when his descriptions appear full and complete, and his localities accurately specified, it certainly is worth while to look for the objects he pro- fesses to have seen. Why do not some of our young naturalists take such things in hand ? Advancing age forbids me. The slender Lizard, Penn. Supp., p. 86. About eight inches long, as slender as a crow-quill; head small, tail blunt and of equal thickness ; body marked from head to tail with lines of pale brown and black, belly lead color ; top of the nose and tail white. Salamandra. 1 once saw, and indeed had in my possession, a Triton or Salamandra, which was sent from New Orleans, of which the following is a short description. I add it in this place because it was a most extraordinary animal. Dusky, speckled with yellowish white, and inclining to blown on the belly ; everywhere except on the belly and tail covered with small warts, so as to re- semble shagreen; tail blunt, with a narrow fin wrinkled longitudinally and trans- versely so as to appear striated and articulated. Length 5 in. .75. The preceding are all the animals which I can find that have once been more or less particularly described, but of which at present no one knows anything. I might have added to the list many that have been described by Rafinesque, but the most of them appear in their coloring, as well as in other characteristics, so opposed to everything known of congeneric species, as to render it extremely probable that the author was laboring under some delusion when he published 14 [January, them. It is well known that he was in the habit of describing things which he never saw, and in his eagerness to claim a priority in discovery, to describe the same object two or three times over under different names. It is to be hoped that the reading of these few pages will turn the attention of naturalists in the Southern and Western States to the investigation of the few species pointed out as forgotten or lost, and that we will not remain long with- out knowing whether they have a real existence. The Committee on Mr. Conrad's " Synopsis of the Genera Paraph ol as and Penicilla " reported in favor of publication in the Journal. A report was read from a Committee appointed at the meeting of 3d inst., to inquire into the expediency of having an Address delivered be- fore the Society at its Anniversary on the 21st of March next, and to nominate a suitable person to prepare such an Address, recommending the same, and nominating Win.

P. Gibbons. Dr. Gibbons proposes the generic name Holconote, and for one species H. Agassizi. For another species the California Academy proposed H. Gibbonsensis. Dr. Le Conte presented a paper for publication in the Proceedings, entitled " Descriptions of some Coleoptera from Oregon, collected by Dr. J. G. Cooper, &c, &c. j" and also a second paper entitled " Synopsis of the (Edemeridag of the United States ;" both of which were referred to Dr. Zantzinger, Prof. Haldeman and Mr. Cooke. 16 [February, February 2th. Vice-President Bridges in the Chair. The Committee on Dr. Le Conte's papers read at the meeting of 21st inst., reported in favor of publication. Descriptions of some new Coleoptera from Oregon, collected by Dr. J. G. Cooper of the North Pacific R. R. Expedition, tinder Gov. J. J. Stevens. By John L. LeConte, M. D. The following species were contained in a collection recently made by Dr. Cooper, and kindly placed in my hands by Prof. Baird. The total number of species collected was nearly 70; among which are specimens of Omus De j e a n ii and Audouini. Among the described species, not before noticed in our territory, is Ancylochira L a n g i i, (Buprestis Langii, Mann.) and among species also found on the Atlantic side of the continent, Haplochile p y g- maea, Lee {Morio pyg. Dej.), Clytus undulatus Say, Monohammus s c u- t e 1 a r i s Say, Hispa v i 1 1 a t a Fabr., Eumolpus a u r a t u s Fabr., Galleruca canadensis Kirby. This indicates, that notwithstanding the extensive collections which have been made both in California and Russian America, the Coleoptera of Western America are still comparatively unknown, and that consequently even small .collectious made by travellers, who have but little time to devote to science, will possess very great scientific value. Cicindela, n. sp. The thorax of the specimen has been destroyed, and the species can therefore be made known only approximately, until the native species of the genus have been properly arranged in systematic order. The species in question seems most closely allied to C. longilabris Say, which it resembles exactly in its markings, but the elytra are less deeply punctured, and of a dull greenish bronze color; the apex is broadly rounded and finely serrate; the suture is armed with a minute spine. The labrum is not longer than is usual in the species of the genus, and entirely resembles in form C. 12-guttata, having only one distinct tooth at the middle; the palpi (of the female) are black; the sculp- ture of the head precisely as C. 12-guttata. Platynus, a species resembling P. obsoletus (Feronia obs. Say,) in every re- spect except that the elytra are somewhat wider. I have not yet investigated this genus sufficiently to pronounce upon the value of such a difference. Carabus oregonensis, cyaneo-niger thorace fere opaco, latitudine vix breviore minus convexo dense intricato-rugoso, antice posticeque angustato, lateribus rotundatis, angulis posticis modice productis, apice rotundatis, lateribus pone medium subreflexis, elytris thorace fere duplo latioribus subtiliter striolato- punctatis, foveis minus profundis serie triplici impressis. Long. -85. One male found at Prairie Paso. This species is closely related to C. taedatus Fabr. (also found by Dr. Cooper,) but the thorax is proportionally smaller and narrower and much more densely and finely rugose ; the rugosities of the head are also smaller, and the impressions less deep ; the striae of the elytra and the impressed foveas are all less marked. Calosoma aenescens, nigroaeneus, crassiusculus, thorace latitudine plus duplo breviore, subtilius dense intricato-rugoso, basi utrinque late foveato, lateri- bus latius rotundatis pone medium modice reflexis angulis posticis paulo productis rotundatis, elytris thorace latioribus seriatim punctatis, foveisque aeneis triplici serie impressis, interstitiis catenatim paulo elevatis, tibiis intermediis rectis. Long. .8- Both sexes, found at Fort Vancouver. This species is very'different from C. tepidum and calidum by the thorax being less rounded on the sides and the pos- terior angles being distinctly prolonged. To Callisthenes it approaches by its form, but the wings are large, and the outer points of the antennae are entirely pubescent. The spaces between the foveas of the elytra are also quite distinctly elevated. 1854.] 17 Ancylochira a d i e c t a, supra splendide viridiaenea, dense punctata, crassius- cula, thorace latitudine fere triplo breviore, antrorsum anguslato, lateribus late rotundatis cuprascentibus, late canaliculate-, elytris lateribus late, sutura an- guste cupreis, costis utrinque 4, scutellarique cum sutura confluente elevatis laevibus nitidis, costa altera subsuturali fere integra adiecta, interstitiis dense punctatis, apice subemarginata. Long. *6, lat '25. One specimen found between Fort Vancouver and Yokolt Plain, in July. This species belongs to a group of species having the form of A. aurulenta and striata, but differs from all the others known to me by having obsolete costae in the in- tervals between the four ordinary costae, and by having an additional costa ex- tending nearly from the apex to the base between the elevated suture and the normal first dorsal costa. The head is entirely free from hair, and is uniformly punctured ; the under surface of the body is bright coppery, tinged with green, moderately punctured; the prosternum is broadly impressed between the coxae, and is not hairy. Ancylochira lauta, supra splendide viridi-aurea, dense punctata, fronte non concava fere glabra, thorace latitudine plus duplo breviore, antrorsum angustato, lateribus late rotundatis cuprascentibus, late canaliculato, elytris lateribus late, sutura anguste cupreis, costis 4, alteraque scutellari cum sutura confluente nitidis laevibus elevatis, interstitiis dense granulato-punctatis, apice vix truncata. Long. -58 '75. Abundant in Oregon, whence it has been brought by Dr. Townsend, Capt. Wilkes' Expedition, Col. M/Call and Dr. Cooper. Resembles the brilliant variety of A. striata, but is distinguished by its more robust form, and by the costae of the elytra being impunctured. A variety occurs in which the elytra have each a broad blue vitta, extending from the first to the third costa. The body be- neath is coppery, somewhat hairy, and the antepectus is impressed between the coxae ; the front has a narrow somewhat smooth medial line. Ancylochira radians, supra splendide'viridi-aurea, dense punctata fronte concava, longe albo-pilosa, thorace latitudine vix duplo breviore, antrorsum an- gustato, lateribus late subrotundatis cuprascentibus, disco late canaliculato, elytris sutura margineque cupreis, costisque quatuor alteraque scutellari cum sutura confluente nitidis elevatis laevibus, interstitiis dense granulato-punctatis, apice subtruncata. Long. *6, lat. -23. One specimen found at Fort Vancouver. It is with some hesitation that I venture to describe this species as distinct : its general form is narrower than A. lauta, and is very much that of A. striata: from the latter it differs by the somewhat concave and pilose front. The pectus is as in the other species, but is densely clothed with long white hair. The under surface is coppery golden, more densely punctured than in the preceding. Ancylochira pl'acida, viridi-aurea, cupreo-tincta, confertissime punctata, thorace latitudine fere duplo breviore, antrorsum subangustato, lateribus late ro- tundatis, postice transversim impresso, elytris vitta cuprea utrinque ornatis, striis punctatis haud distincte impressis, apice conjunctim rotundatis, Long. 29. Collected by the late J. K. Townsend, in Oregon, and given me by Mr. Will- cox, as Phcenops placida of the Berlin museum. The form of body is more cylindrical than in the other species known to me; the pectus is not canaliculate, and the prolongation of the sternum is broader and more obtuse than in A. decora, or the other species with which I have compared it. The insect, though differing from Ancylochira in having the scutel slightly pointed behind, ap- proaches much nearer to that genus than to Phaenops, and until a revision is made of the genera of our native Buprestidae on more natural characters than have been hitherto employed in their study, should be suffered to remain where I have placed it. Ellycbnia facula, elongato-elliptica, atra tenuiter pubescens, thorace latitu- dine vix breviore, disco convexiusculo, lateribus et apice concavis reflexis punctatis, macula submarginali lunata rosea ornato, elytris dense punctulatis linea unica dorsali obsoleta utrinque notata. Long. *52. One specimen, Prairie Paso, differs from E. corrusca by its less dilated 2 18 [February. form, and longer thorax, and by Ike presence of only one elevated line on each elytron. Lytta Cooperi, atra, capite thoraceque laete fulvis, nitidis laevigatis, illo basi subemarginato, ante oculos nigro, hoc pentagonali, latitudine breviore, an- gulis lateralibus acatis, dorso deplanato, elytris lineis elevatis grosse reticulatis ; antennis extus incrassatis, articulis rotundatis, tibiis posticis calcari externo lon- giore dilatato. Lous- - 73. Wenass river, to Fort Colville. It affords me great pleasure to dedicate this fine species to Dr. Cooper, to whose taste for natural history we are indebted for the present interesting collection. This species belongs to group (A b) of my synopsis of Meloides, (Proc. Acad. 6, 334,) near L. vulnerata, but is very distinct by the reticulated elytra. Ditylus gracilis, elongatus ater, tenuiter pubescens, thorace latitudine lon- giore, obovato postice angustato, lateribus antice rotundatis, dense punctulato, late profunde canaliculato, disco utrinque ante medium subfoveato, elytrts subti- liter granulato-punctatis, lineis 4 distinctis subelevatis. Long. 63. One specimen found between Fort Vancouver and Yokolt Plain, in July. Very different from the two species mentioned on p. 20, by the more slender form and elongate thorax; the dorsal channel is dilated and bifurcated towards the apex and base of the thorax. Phymatodes aeneus, osneo-piceus, parcius pubescens, thorace latitudine bre- viore, rotundato punctulato, antice posticeque marginato, elytris thorace paulo latioribus, nitidissimis, parce punctatis, femoribus valde clavatis, antennarum basi rufescente. Long. *3. One specimen found betw r een Fort Vancouver and Yokolt Plain. Somewhat resembles in appearance P. sereus. Asemum a s p e r u m, nigro-piceum, tenuiter pubescens, capite scabro-punctato, oculis magnis valde emarginatis, thorace latitudine breviore rotundato, punctato, medio late excavato, versus latera punctis elevatis exasperato, elytris subtiliter scabris, lineis duabus obsoletis vix distinctis. Long. *7 *9. Prairie Paso, July to August. This fine species seems intermediate between Criocephalus and Asemum ; the eyes, although nearly as large as in the former genus, are deeply emarginate; the antennae are hardly half as long as the body, and pubescent. The discoidal excavation of the thorax does not extend much in front of the middle. Crossidius ? h i r t i p e s, ater, thorace confertim punctato, latitudine breviore, lateribus obtuse armatis, basi marginata, disco utrinque pone medium subfo- veato, elytris confertim subtilius punctatis, fulvis, sutura basique nigro-margi- natis, abdomine sanguineo, basi obscuro ; subtus parcius longe pilosus, tibiis intus dense pilosis. Long. *5 One specimen, Wenass river to Fort Colville. The palpi and antennae are destroyed: it is possible that this should form a separate genus, but the man- dibles are emarginate at tip as in Crossidius, from which it seems to differ in having the thorax obtusely armed at the sides, as in Purpuricenus. The upper surface may have been hairy, as in C. testaceus, but the hair is now en- tirely removed. The elevated lines of the elytra are hardly visible. Toxotus flavolineatus, niger, flavo-pubescens, thorace antice posticeque valde constricto, nitido parcius punctulato, canaliculato, lateribus tuberculo magno acuto armatis elytris a basi angustatis, thorace duplo latioribus dense punctu- latis et rugosis, margine a basi fere ad apicem vittaque dorsali postice evanes- cente antice abbreviata utrinque ornatis, apice intus subtruncata. Long. 1*0. One specimen, Fort Vancouver to Yokolt Plain. On each side of the yellow dorsal vitta is a distinct elevated line. Strangalia vitiosa, nigra, flavo-pubescens, capite rufo-variegato, thorace confertim punctato, latitudine breviore antrorsum angustato, lateribus subangu- latis basique subito depressa testaceis, disco nigro, subcanaliculato, postice utrin- que oblique impresso, elytris punctatis fiavis, a basi angustatis, macula laterali 1854.] VJ ad medium apiceque late nigris, ilia oblique intus emarginata, pedibus testaceis femoribus tibiisque posticis ad apicem genubus tarsisque nigris, antennis pallido annulatis. Long. -7. Two specimens, one having the third joint of the antennae black, the other, having it pale at the base, like the following joints : Fort Vancouver and Prairie Paso. This species resembles very closely S. obliterata, but the thorax is shorter and more dilated posteriorly; the impressions are much stronger, and the disc is separated from the base by a sudden declivity ; the basal margin is also yellow, and there is no trace of the two elytral spots before the middle ; the apex of the elytra is not at all rufous. In the description of S. obliterata (Journ. Acad. Nat. Sc. 2d ser. 1, 328) the testaceous sides of the thorax and the annulate antennas are not mentioned ; they were overlooked on account of the dark color of the specimen from which the description was made. Plectrura product a, nigro-picea, parce griseo pubescens, guttulis flavo-pu- bescentibus parce adspersa, confertim rugose punctata, thorace callo dorsali parvo, elytris callis subquinque-seriatis nitidis parce ornatis, apice non crenula- tis, singulatim longe acuminatis, antennis annulatis. Long. 5. One specimen, Fort Vancouver. This species does not agree with the des- cription of P. sprnicauda Mann. (Bull. Mosc. 1852, 366). The thorax has a strong: lateral spine, with some smaller ones around it, as required in the generic description, but the tips of the elytra are not crenulate; the smooth tubercles form five series, of which only the outer one is entire; the others are imperfect, containing only three or four tubercles each ; the sutural one is indistinct, the second ends just behind the middle ; the third and fourth are abbreviated at each end, commencing about one-third from the base, and ending at one-fifth from the apex ; the scutellum and a little thoracic line anterior to it are more densely pubescent, with yellow hair, than any other portions. Tetraopes oregonensis, niger, capite thorace elytrisque coccineis (pallide pubescens ?) thorace nigro-4-punctato, disco medio subito elevato, antice pos- ticeque valde constricto, lateribus subito valde dilatatis, parcius punctate elytris parce punctatis puncto humerali, duobus ante medium, altero utrinque pone medium, scutelloque nigris, pedibus antennarumque articulo lmo coccineis. tarsis, genubus, tibiisque posticis nigris. Long. -55. Wenass River to Fort Colville. This species has the form of T.femora- t us Lee, but the thorax is still more dilated on the sides. From T. basalis (the only other species known to me in which the base of the antennae is red) it is easily known by the sudden elevation of the disc of the thorax. The pubescence has been removed by the alcohol, and I am therefore uncertain whecher the antennae are annulated. The black spots of the elytra are in the usual position, but are very small, and, with the exception of the humeral one, disappear entirely in many specimens. Coccinella subversa, hemispherica nigra, capite ante oculos albo (ore, cly- peoque feminae nigris) thorace subtiliter punctulato, lateribus rotundatis, macula antica ad angulos quadrata, apiceque albis, elytris distincte at subtiliter punctu- latis scutello nigro, et praecipue macula obliqua ad medium nigra notatis. Long. '2. This species resembles closely C. c a lifo r n i c a, but is smaller, and the elytra are much more distinctly punctulate. Hippodamia mo est a, rufescente-nigra, nitida, dense subtiliter pur,ctulata, macula frontali rhomboidea, thoracis margine laterali antice posticeque latiore, linea media ante medium, guttisque dorsalibus duabus albis, elytris thorace lati- oribus macula laterali triangulari ad quadratem posticum alba ornatis. Long. 3. Prairie Paso. The ungues are acutely toothed, as in most species of the genus ; the white triangular spot of the elytra is between one-fourth and one-fifth from the apex, and is somewhat dilated along the margin in one specimen. Necrophorus p o 1 1 i n c t o r, niger, thorace ovali, transverso, marginibus late depressis, disco tenuiter canaliculato, fortius transversim impresso, elytris par- 20 [FEBRUARY^ cius punctatis macula ad medium laterali in epipleuram extenso, aJteraque parva lunata anteapicali rubris, pectore flavo-pubescente, abdomine breviter griseo- ciliato, tibiis posticis rectis. Long. -58. Fort Vancouver to Yokolt Plain. Of the species found in the Atlantic States, this approaches most nearly toN. sexpustulatus; the thorax is almost pre- cisely as in that species, but is more profoundly impressed j the margin is punc- tured, the disc in one specimen is smooth, in the other obsoletely punctulate^ The antennae are entirely black. Necrophorus confossor, niger, thorace ovali, transverso marginibus punc- tatis late depressis, disco parce punctulato canaliculato, transversim valde im- presso, elytris sat punctatis fasciis duabus dentatis (prima ad suturam extendente. epipleurisque auruntiacis, pectore anoque fiavo-piloso, antennarum clava aurun- tiaca basi nigro-picea tibiis posticis rectis. Long. '68. One specimen, Prairie Paso. This species closely resembles in appearance N. marginatus, but the thorax is less narrowed posteriorly, and the depressed margins are considerably broader, being, in fact, very much as in the preceding species, or N. n i g r i t a. Alophus d idy m u s, niger, opacus, ochreo-fusco subtiliter dense pubescens y rostro canaliculato, thorace dense punctato, latitudine vix breviore antice pro- funde constricto lateribus antice paulo rotundatis tenuiter canaliculato, vitta utrinque sublaterali densius pallide pubescente, elytris thorace sesqui latioribus, dense subtiliter rugose punctulatis, ochreo nigroque subtesselatis, gutta utrinque ante medium, alteraque ad dodrantem densius pallide pubescentibus. Long. *48. Fort Vancouver ; collected also by the late J. K. Townsend. Somewhat smaller and narrower than A. alternatus Say, and readily distinguished by the different form of the thorax and by the entire absence of elytral striae. I have adopted the name under which it is known in the Berlin Museum. I have several species of Curculionidae, from various sources, collected in Ore- gon, but being unable to determine with certainty the genera to which they belong, and being in truth not at all satisfied with the elaborate arrangement used by Schonherr, I forbear describing them until I can bring them all together ; re- flecting that more confusion may be produced by referring a species to an impro- per genus, than by suffering it to remain undescribed. Synopsis of the CEde.meridje of the United States. By John L. Le Conte, M. D. Although I can contribute but two new species, at present, to this small family of Coleopterous insects, it seems desirable that a concise list of the species already described should be presented, as the descriptions have become somewhat scattered, and some of the species have been placed in wrong genera. The trenera allied to Xylophilus are placed in this family by some entomologists, but the association does not seem natural, and the species are therefore not in- cluded in this synopsis.

For the complete synonymy of this species, which is found on both conti- nents, see Schmidt's memoir above quoted, and Redtenbacher's Kiifer, p. 623. The insect is most abundant in the vicinity of our cities, and has probably been introduced by commerce. The synonymy omitted relates to its occurrence on the eastern continent, and therefore has no place in our local fauna. Redten- bacher very properly unites Nacerdes with Anoncodes.

One specimen: New Mexico; collected by Mr. Fendler. The base of the thorax is only about two-thirds as wide as the apex ; the dorsal line is fine, but the transverse impressions are well marked. The mentum tooth is narrow, and very slightly emarginate at the tip. In these four species, the under surface of the tarsi is glabrous, and the outer margin of the two posterior pairs is deeply grooved. In my synopsis of Pteros- tichus (Journ. Acad. Nat. Sc.,2d ser., vol. 2) it will be seen that in closely allied species, the latter character is of little value. The same would seem to be the case in the present group, and no better proof is required than the remarks made by Baron Chaudoir, on the page immediately opposite that in which he insists strongly on the great assistance which is derived from it in distinguishing Cala- thus from Pristonychus. The real difference between the genera is precisely that so long ago made known by Erichson, viz., the length of the paraglossae, which in Calathus do not extend beyond the ligula, while in Pristonychus (and likewise in Pristodactyla and Taphria) they are very distinctly elongated. Anchtjs Lee. Palpi tenues, acuminati, maxillares articulo ultimo paulo longiore ; antennae filiformes, articulo lmo crassiore,. et longiore; mentum dente medio simplici; ligula truncata, paraglossis angustis longioribus. A curious insect, having very much the appearance of Diaphorus, but having the head less constricted posteriorly, and the elytra rounded at the apex ; the thorax is long and cordate, almost turned into a pedicel at the base, with the impressions elongate and very narrow ; the elytra are twice as wide as the thorax, oblong and convex, with the humoral angles rounded, and the apex scarcely 1854.] 39 sinuate ; the striae are deep and moderately punctured, the intervals are narrow, convex, and are each marked with a row of very fine punctures, from which pro- ceed very short hairs. The legs are moderately long, the anterior tibiae scarcely dilated at the apex, with the emargination extending nearly to the middle ; in the male the first three joints of the anterior tarsi are very slightly dilated, and furnished beneath with a few papilla3. The antennas are very slightly thickened externally ; the first three joints and the base of the fourth are smooth, but furnished with a few scat- tered hairs ; the first is longer than the third, and somewhat thicker than in the other genera of this group. The paraglossae are narrow, curved, and longer than the truncate ligula ; the tooth in the emargination of the mentum is moderately large, and almost acute at the tip. The palpi are slender and moderately long ; the last joint is elongate oval, and almost acute at the tip; that of the maxillary palpi is distinctly longer than the penultimate joint. It seems by its characters closely to approach Stomis, but the mandibles are not so long and the labrum is not at all emarginate. By the structure of the anterior tibiae as well as by the sexual characters, it evidently belongs to the* present group. 1.

Finding in this insect many of the characters of Stomis, I was misled by the very poor description of Mr. Laporte, (Etudes Entom. 1, 72) with which it agrees as closely as could be ex- pected, in every respect except size. Baron Chaudoir, as I have already ob- served in my synopsis of Pterostichus, (Journ. Acad. Nat. Sc, 2d ser., 2,) has since stated that Mr. Laporte's insect is Feronia fastidita Dej. Under these circumstances, the specific name adopted by me under error falls, and I take pleasure in giving to the insect the name under which it was communicated to me by Dr. Harris. Rhadine Lee. This genus only differs essentially from Platynus by the greater length of the third joint of the antennae, which is one half longer than the fourth joint ; the first joint is short, being about one-half longer than the second. The form of body is that of the first division of Platynus, but the margins of the thorax and elytra are more broadly rerlexed, and the elytra are strongly sinuate at the apex ; the antennas and feet are also longer. These characters give the insect a considerable resemblance, in general appearance, to Anophthalmia. 1.

Long. "41. Le Conte, Ann. Lye. 4, 219. One specimen (male) found near St. Louis, Missouri, was kindly given my by Dr. Engelmann. In the State of Ohio, Dr. Schaum procured a dark brownish black specimen, in which the sinus of the elytra was so strong, as to form on each side of the apex a tooth; the specimen was a female, but not having it be- fore me for examination, I cannot determine whether the difference is to be re- garded as sexual or specific, Platynus Bon. (emend. Brulle.) Under this generic name I group, after the example of Mr. Brulle, those spe- 40 [April, cies upon which Bonelli formed his three genera, Platynus, Anehomenus, and Agonum. My reason for preferring for this assemblage of species the name Platynus, is merely, that such was the name chosen by Mr. Brulle, who was the first entomologist to perceive the necessity of merging the groups into one genus. Two years afterwards, Erichson proposed to call the assemblage of Bonelli's three genera by the name Anehomenus, alleging that Platynus was in- applicable to most of the species, and that it had, moreover, been employed (in the form Platyna) for a genus of Diptera ; the first point, in the present state of nomenclature, need not occupy our attention; the second point is also without weight, since Platyna was proposed as a genus many years after the establish- ment of Platynus by Bonelli, and before it was shown that the latter genus in- cluded any other form than that to which it was limited by the author. The name Platynus was consequently not vacant, and its application in any form, to a genus other than that intended by Bonelli was improper. This genus, as here understood, contains a very large number of species, all agreeing in having the paraglossae scarcely longer than the ligula ; the mentum tooth distinct and not emarginate ; the palpi slender, with the last joint ahout equal to the preceding; the first joint of the antennae moderately thick, not longer than the third, which again is not longer than the fourth; the tarsi are filiform, and the ungues entirely smooth. The antennas are usually filiform, but sometimes setaceous. The form of body is variable, usually somewhat slender, with the elytra nearly twice as wide as the head or thorax, and oval or oblong, sometimes elliptical ; the elytra are either rounded, truncate or emarginate at the base, usually slightly sinuate at the apex, and sometimes almost truncate, in which case a form of body results not unlike Dromius or Metabletus. Occasionally the form of body is stouter, and the elytra are hardly one half wider than the thorax ; and in some west- ern species, unknown to me, the form is said to be almost similar to Calathus ; these latter species have been separated by Motschulsky as Tanystoma, (after- wards changed to Tanystola) ; the only characters given are, that the last joint of the palpi is longer than the preceding, and the posterior angles of the thorax ob- tuse. Scaphiodactylus (Chaudoir) is also said to have the palpi as in Tanystola, but the posterior angles of the thorax are acute. Not having identified these genera, I can with propriety say nothing in regard to them. The thorax is very variable in form, being sometimes oval, sometimes cordate, square, or rounded ; the margin is sometimes strongly reflexed, sometimes hardly visible. The interval between the second and third stria; of the elytra is always marked with punctures, or fovae, varying in number from three to seven ; some species, not known to me by personal observation, are described as having but two punctures. To facilitate the determination of our species, the following division into groups may be found useful. A.

The cases of difficulty, in referring species by this table, will be but few ; a species (P. quadratus) is placed in (f.,) which might, with almost equal propriety, be placed with (d.) ; still, the form is less slender, and the margin of the thorax much more obvious than in the latter group. P. crenulatus in group (F.) differs from the others of the same group, by the broader and more quadrate elytra ; still, its chief affinities appear to be with that group, and I have, therefore, not separated it from its allies. A. The species of this group are of a slender form and not winged ; the legs and antennae are long ; the thorax is obovate, usually elongate ; the posterior angles are obtuse and rounded at the apex ; the lateral margin is strongly reflexed, and is broader than usual. The elytra are regularly elliptical, with no distinct hu- meral angles ; they are sinuate towards the tip ; the lateral margin is broader than in any other group, and is strongly reflexed. This group corresponds to Platynus of Bonelli and Dejean. 1.

This species resembles in appearance P. sinuatus, &c, below, but from the absence of wings, and from the form of the thorax, I am induced to place it in the present division. The margin of the thorax is not as wide as in the other species, but is a little dilated towards the posterior angles ; the basal impressions are deep, and are destitute of punctures or lines. The elytra are slightly convex, and their lateral margin is somewhat narrower than in the preceding species. B a. Composed of winged species, of a piceous black color and slender form ; the antennas are long and setaceous; the thorax is strongly margined, a little wider than long, somewhat narrowed posteriorly, with the basal angles obtuse, neither prominent nor rounded ; the posterior transverse impression is strong, and the basal impressions moderately long and deep. The elytra are more than twice as wide as the thorax, truncate at base, finely margined, sinuate towards the extremity ; the humeral angles are rounded ; the striae are fine, and the third in- terstice has three punctures, the first being placed in the 3d stria, the other two in the 2d stria. 5.

Long. *42. San Francisco, California ; very abundant. Specimens occur with three, four, and even five punctures on the third interstice of the elytra ; the impressed lines of the basal impressions of the thorax are less distinct than in the preceding ; the antennae and palpi are nearly black ? the tarsi are sometimes dark piceous. I have distributed this insect under the name Anch. brunneo-marginatus (Mann. Bull. Mosc. 1843, 196,) but on reconsidering the matter, I find so many points of disagreement, that 1 am obliged to propose a new name. His description reads : "Apterus, niger, depressus, capite laevissimo inter antennas impresso, thorace longiore, subcordato, lateribus refiexo-marginatis, angulis posticis acutiusculis, 44 [April, elytris oblongo-ovalibus, apice sinuatis, leviter striatis, punctis tribus minutis impressis, antennis pedibus, thoracis elytrorurnque margine rufo-brunneis. Long. 4* lin. lat. H lin." With regard to the value of the first word of this diagnosis, I will merely ob- serve that it occurs also in Count Mannerheim's diagnosis of Anch. maeulicoUis (1. c. 199,) which, however, I found at San Diego, in July, flying about in the evening twilight in such numbers as to be a source of great annoyance. B c. The species of this group are moderately large, winged, and a pure shining black color; the thorax is slightly cordiform, with the posterior angles rectan- gular; the dorsal line and anterior transverse impression are deep ; the basal impressions are large, moderately deep and finely punctulate; the lateral margin is moderate and is strongly retlexed, and slightly diaphanous in a strong light. The elytra are more than one half broader than the thorax, truncate at base, slightly sinuate at the extremity ; they are somewhat flattened on the disc, and declivous towards the margin ; the stria? are deep, and the third interstice has three impressed punctures. I regret to be partly answerable for the confusion introduced among the species of this group, by mistaking those which have been already described, and incautiously admitting some which are not sufficiently distinct. Having carefully re-examined the subject, I hope that the results, here arrived at, may be found corrrct. 10.

The description last cited was made from a badly preserved specimen, in which the wings had probably been pulled off to enable the elytra to be brought together ; at least, on raising the elytra, I find fragments of the wings still remaining. The distinctive characters of the species are the larger size, the less distinct posterior angles of the thorax, (which are almost obtuse and very slightly rounded,) and the less lustrous and more flattened elytra. The .fine punctures of the striae are sometimes almost invisible. Dejean mentions four elytral punctures ; the second one, however, is abnormal. 11.

He says, in comparison, with the preceding, "le corselet est a peu pres de la meme forme ; seulement les bords lateraux sont un peu moins largement deprimes." This difference, if it exists, is by no means obvious. The only satisfactory characters I can find are the smaller size, the more shining, less depressed and less deeply striate elytra. a.

Although the difference between this and P. sinuatus seems very considerable, in a large series of the form (*) they seem to disappear ; 1 have therefore hesitated to propose a new name lor this, and consider it, like the previous one, as a race under P. sinuatus. C d. A group containing winged species, evidently allied to P. exte n si collis &c, but differing by having only three elytral punctures ; the feet and antennas are entirely black. The thorax is flattened, moderately margined, the margin growing broader towards the base; it is almost longer than wide, very slightly' narrowed posteriorly, hardly sinuate on the sides, truncate at base, with the pos- terior angles rectangular, not rounded ; the basal impressions are very long and finely rugous ; the elytra are flattened, truncate at base, slightly sinuate at apex ; the striae are deep and fine, the interstices flattish, the 3d with three impressed punctures ; the antennas are filiform. 12.

A group of extreme complexity, containing winged species of metallic colors, bluish or greenUh, with the base of the antennas, the feet, and occasionally the thorax rufous or pale piceous. The antennae are long and filiform ; the thorax is occasionally a little longer than wide, never much narrowed posteriorly, the margin fine, but strongly reflexed, moderately rounded on the sides; the base is oblique each side, and the posterior angles are obtuse and sometimes moderately rounded ; the basal impressions are long, and posteriorly are marked with a short line. The elytra are elongate, about twice as wide as the thorax, scarcely sinu- ate posteriorly, striae deep, but usually fine, the interstices hardly convex, the third with four to seven punctures, varying in the same species. By arranging the different forms as races under the more distinct species, this group appears to be capable of being reduced to order. 14.

I am doubtful about the propriety of referring this to Dejean's species, which is described as having the head and thorax obscure greenish-bronzed ; slight traces of such color may be perceived in some of my specimens, but usually they are of a brownish black color, slightly tinted with bronze. In the uncertainty which hangs over many of the species, and under my great want of success in collecting (or perhaps in identifying) the species found in California, it would be hardly prudent to pro- pose this as a new species. The refiexed margin of the thorax is distinct, but very narrow. D f. Winged species mostly of a black color, with the legs and antennae of the same color as the body ; the thorax is rounded, with the posterior angles very obtuse, or altogether rounded; the margin is moderately broad, usually slightly dilated and refiexed towards the base ; the basal impressions are broad and shallow ; the elytra are not much wider than the thorax, truncate, or even subemarginate at the base, rounded and hardly perceptibly sinuate towards the extremity ; the in- terstices are mostly fiat, and the third has three punctures, the second of which, except when otherwise stated, is placed on or near the third stria.

Sufficiently distinct from P. melanarius, by the slightly bronzed color, more obtuse and more rounded posterior thoracic an- gles, and less deep and impunctured elytral striae. From P. metallescens, which it resembles in the form of the thorax, it is easily known by the smooth elytral striae and more dull color. From P. moerens, it is distinguished by the wider thorax with more rounded base and less distinct posterior angles. Dr. Harris sent a specimen as Ag. collare Say ; the impunctured striae, how- ever, prevent it from being referred to the species described by him under the same name in the Trans. Am. Phil.

The first specimen described by me was defective in having very small elytral punctures, whereby I was led into the error of describing the elytra as having only three punctures on the third interstice. The thorax is larger and wider in proportion than the last spe- cies, but the elytra are wider and less elliptical than in the remaining species of this group, and the stria? are deeper. I am somewhat doubtful about referring Dejean's description to this species, since not only the first joint of the antennae, but very frequently three or four joints are paler than the outer joints, and the striae of the elytra, in comparison with the following species, could hardly be called fine. As, however, Dejean implies that the sides of the thorax are some- what reflexed posteriorly, I must acknowledge that my reference of his species to what is described below as P. picipennis, must be considered faulty. 45.

Many of the specimens have two slightly impressed foveae before the middle of the thorax, but some are found without such impressions.

A type of 0. cinctus, given me by Dr. Mel- sheimer, does not differ in any essential point from the other specimens. I have never seen any in which the lateral bead of the thorax was not testaceous, and am inclined to believe that Mr. Say had not a specimen of his Feroui a parmata before him when he described 0. cinctus. The basal impressions of the thorax are sometimes obsoletely punctulate, in other specimens they are quite smooth ; the elytra are sometimes nearly uniform brownish yellow, sometimes piceous, with the shoulders and sides indistinctly brown. 2. 0. micans, nigro-piceus, nitidus, cyaneo-micans, thorace rotundato, transverso, marline tenui testaceo postice subreflexo, basi utrinque vix late foveata, elytris ovalibus. basi emarginatis, tripunctatis, tenuiter striatis, mar- gine tenui testaceo, antennis palpis pedibusque flavis, ill is extrorsum fuscis.

On Fossil Coniferous Wood, from Prince Edward Island. By J. W. Dawson. Under the impression that any facts relating to the formation which lias af- forded the interesting reptilian fragment recently described by Dr. Leidy in the Journal of this Academy, will prove interesting, 1 beg leave to communicate the following results of microscopic examinations of the coniferous wood referred to in my note appended to Dr. Leidy's paper. I may premise that Prince Edward Island, which extends in an east and west direction about 130 miles, with an extreme breadth of about 35 miles, consists almost entirely of bright red sandstones, similar to the matrix of Dr. Leidy's fossil, with occasional bands of red clay, conglomerate and arenaceous and con- cretionary limestone. Over a large part of the island, these beds dip at very small angles to the northward. There are, however, some tracts in which the beds undulate to the southward and south-east. These red rocks, in their mine- ral character, much resemble the new red sandstone of Cornwallis and other 1854.] 6 r> places in Nova Scotia, and Dr. Gesner, in his Report on the Geology of Prince Edward Island,* notices the occurrence of trap dykes at two localities on the northern coast, a circumstance which still farther increases the resemblance. There are, however, a few places in which beds occur which much resemble the upper parts of the coal formation of Nova Scotia, and it is in these localities chiefly, though I believe not exclusively, that the coniferous wood in question occurs, along with a few other vegetable fragments, for the most part very im- perfectly preserved. Some interest, therefore, attaches to these fragments of fossilized wood, as a means of comparison between the oldest portions of the red sandstone formation of Prince Edward Island, and the inferior members of the coal formation on the opposite coasts of Nova Scotia and New Brunswick, in which coniferous wood is also of very frequent occurrence. 1. Coniferous wood from Gallas or Gallows Point , west side of Orwell Bay. At this place, which I visited in 1842, the following beds appear in descending order, the dip being to E. S. E. at angles of 6 to 8 : red and brownish sand- stones, gray sandstone with bands of concretionary limestone, and containing carbonized vegetable fragments, some of them resembling catamites, but without joints, gray and brown shales or indurated clays; brownish sandstone, with large trunks of trees silicified. One of these trunks measured three feet in its greatest diameter ; they are prostrate and somewhat flattened. I have no doubt that these rocks underlie the ordinary red sandstones of the island, and Dr. Ges- ner, who examined them in 1847, takes the same view, affirming them to be carboniferous, and stating that he found in them catamites and stigmaria, which, if well characterized specimens, would go far to confirm that conclusion. My specimens of fossil wood from this place are perfectly silicified, and of a dark clove-brown color. They are much fissured in the direction of the medul- lary rays, and the fissures are filled with flesh colored sulphate of barytes. Under the microscope, transverse slices show a somewhat dense tissue of quadrangular cells arranged in rows. Longitudinal slices in the direction of the medullary rays, show parallel elongated cells, medullary rays not strongly marked, and traces of hexagonal discs of the Araucarian type on the walls of the cells. Two rows of these discs occupy the whole breadth of a cell. 2. Specimens from Des Sables and Crapaud. At these localities the only rocks seen are the ordinary red sandstones, and the coniferous wood is found only in loose fragments on the surface. From the large quantity scattered over the fields, and the general scarcity of travelled boulders in this part of the island, I have no doubt that it now lies over or near its original site. The specimens from this place are dense and without fissures, and have a structure quite similar to that of the wood from Gallas Point, though not in so perfect preservation. 3. A specimen from, some part of the sovth shore of Prince Edward Island , now in the collection of the Puton Literary Society. This specimen was obtained from a person who stated that it was a portion of a large trunk. It still retains in its crevices remnants of the matrix of coarse reddish sandstone. It is cracked in lines radiating from the centre, and is perforated by numerous vermicular holes, now somewhat flattened, but which were probably the burrows either of Teredines or xylophagous larvae. Some parts of this specimen retain their structure in a very perfect condition. It is of precisely the same character with that already described, and shows one or two rows of discs on each cell. All these specimens probably belong to the same genus, and perhaps to the same species of coniferous trees ; and they all differ materially from the conife- rous wood of the coal formation. I have slices of the latter from various parts of New Brunswick, Nova Scotia and Cape Breton, some of them from the new- est beds of the coal formation. All of them are of much coarser texture than the specimens from Prince Edward Island. The cells are wider, and usually with three or even four rows of discs, and the medullary tissue is more strongly marked. In the closeness of the cellular tissue, fewer rows of discs, and fine- ness of the medullary rays, the Prince Edward Island specimens, though dis- tinctly of the Araucarian type, approach more nearly to the modern pines of this * 1847. 6 64 [April, country than to those of the coal formation. They therefore afford no proof that these lower members of the red sandstone formation of Prince Edward Island are of carboniferous date, but would rather tend to connect them with the overlying beds which have afforded the remains of the Bathygnathus borealis. The occurrence, however, in this position, of rocks so nearly resembling those of the upper coal formation, renders it probable that no very sudden or marked physical changes intervened between the deposition of the latter and that of the new red sandstones, and thus furnish an argument in favor of the Permian date of this last deposit.* Description of a species of Crane found in Wisconsin^ presumed to be new* By William Dudley, of Madison, Wisconsin.

Description of Fossil Trees in the coal rocks near Greensburgh^ Westmoreland county ) Pennsylvania* By Alfred T. King, M. D. Throughout nearly the whole of Western Pennsylvania, but more abundant in particular localities, may be found fragments of immense silicified trees lying on the surface of the ground. About seven miles east of Greensburgh there is a re- markable locality. Here may be seen immense logs from six to eight feet long, and from one to four feet in diameter, strewed over acres of ground. After the closest examination, I have been unable to find any very clear indications of high vegetable organization in these silicified trees. Indeed I have been unable, after the closest scrutiny, to discover a single specimen of fossil plant in our vast carboniferous series, of higher organization than vascular Cryptogamia. I might, perhaps, except some specimens, which I first saw a few weeks since in Beaver county, Pa., of Trigonocarpum? This is the fruit of a tree, which some have supposed to be allied to the Palms ; of this, however, there is still great doubt and uncertainty. Many of the specimens of silicified wood contain numerous and beautiful crystals of quartz scattered throughout their interior structure, which would seem to indicate that the silicifying process must have taken place whilst the wood was immersed in water of high temperature. Whilst excavating a tunnel on the Pennsylvania Railroad near Greensburgh, a stratum of very compact sandstone of about fifteen feet in thickness was opened', which contained vast quantities of trunks and limbs of trees, some per- meated with silicious and pyritous matter, whilst others have left only their imprints, the woody matter having been converted into coal, which forms a thin * For description of the Newer Coal Formation of Nova Scotia, see Journal of London Geol. Soc. vol. 1. p. 322 ; and Taylor's Statistics of Coal, p. 196. 1854.] 65 but beautiful pellicle, covering the impressions of the plants. These trunks and Jimbs are of all sizes, from an inch to nearly three feet in circumference, strewed about, and piled upon each other in the most irregular manner, and so numerous that scarcely a fragment of rock was thrown out which did not contain either a vegetable impression or a silicified stem. Although in the shale above, vast piles of detached fern leaves were found, be- longing principally to the genus Neuropteris t accompanied with numerous im- pressions of Calamites, yet no species of fern was discovered in the sandstone, with the exception of two specimens, both of which belonged to distinct genera. The one was a Pecopteris, and the other was the Cyclopteris trichomanoides , Among the numerous arborescent fossil plants which were found in this sand- stone, was an entire tree of immense magnitude, lying prostrate, about four feet above the Pittsburgh seam of coal, and about thirty feet beneath the surface. The part which was removed measured twenty six feet in length, and two feet ten inches in circumference at the base. From the size of the two main branches which enter the rock on the opposite side, I infer that this tree may have been from forty to sixty feet in height. At the base, it was much flattened by the pressure of the superincumbent weight, but strange as it may seem, the branches still retained nearly their original cylindrical form. It was entirely enveloped in a coating of pure bituminous coal, varying from a quarter of an inch to one inch in thickness. Its interior was filled with sand, mixed with sulphuret and car- bonate of iron, which much increased its weight, but there were no indications of vegetable structure. The thin vegetable band, which alone remained con- verted into pure bituminous coal, may have surrounded an axis of more perishable material, which, when the tree was removed from its original position by the storms or the Waves, rapidly decayed. Its hollow interior would necessarily be filled with sand, broken shale or other sediment which was brought by large rivers into that turbulent sea, the bed of which was gradually subsiding. This view is corroborated by the fact, that the rock in which this plant is found imbedded, and which constituted its matrix, presents an entirely different appear- ance in color, and in some degree in lithological character, from that which fills the interior of the fossil tree. Although there were numerous, but irregular longitudinal flutings, both along the main irunk and its branches, yet I could discover no indications of those beautiful scars, so characteristic of arborescent ferns, and of the genus Sigillaria, which indicate the spots where the petioles of the leaves articulated with the stem ; and hence I infer that this tree should not be referred to either of those families of plants. The question naturally arises, to which of the three great divisions of the vegetable kingdom do these fossil trees belong. Do they belong to arborescent ferns, gigantic palms or lofty pines ? Are they of exogenous or endogenous growth ? It has been said by fossil botanists, that true exogena? and endogenae have been found in the carboniferous rocks of Europe. I have, therefore, been much inter- ested in discovering some clear indications of these highest forms of vegetable structure, in the coal measures in this country ; but 1 have thus far failed, unless the specimens to which I have already alluded, should on further examination, prove exceptions. I am aware that M. Brongniart has placed the Sigillariae among the exogenae, but with all due deference to his high authority, I must say that I have been unable to find in that family of fossil plants any evidence of pith, bark, con- centric rings, medullary rays, or other indications of so high a structure. Since writing the above,! have made another examination of the specimens of fossil trees, and believe that I was at first mistaken in regard to some of them being branches. The rock in which they were found had been blasted, and consequently the fossil trees were much broken. The largest entire piece which I saw was not more than four or five feet in length. These facts may have some bearing upon their position in the vegetable scale. 66 [April, Description of fossil fruit found in the Carboniferous BocJcs of Beaver County , Pa* By Alfred T. Kijxg, M. D., of Greensburg, Pa. Mr. Mendenhall, of New Brighton, showed me several specimens of fossil fruit imbedded in solid sandstone, belonging to the carboniferous series of that neighborhood. And through the kindness of George W. Tyler, Esq., editor of the Boston Herald, I procured a specimen for description. These specimens bore considerable resemblance, both in form and size, to the fruit of the Butternut, Juglans cinerea. There have been found in the coal strata in Leicestershire, England, a number of species of a three cornered fruit, to which the generic name Higonocarpum has been given. Possibly, the specimen which I am about to describe, may be referred to that genus. This is a drupaceous fruit, of an ovoidal shape, from two inches and a quar- ter to three inches in length, and from one inch and three quarters to two inches and a half in breadth, and weighs from two and a quarter to three ounces* Its external surface is nearly covered with a thin coating of bituminous coal ; a large portion of which, however, adheres to its matrix. This coal was formed, I presume, by the carbonization of its pericarp. Its interior is filled with coarse grained sand, similar to the rock in which it was imbedded. The epicarp i formed of three nearly equal valves, joined by three prominent sutures, uniting in a point at the apex. Between the sutures are seen a number of nearly parallel and prominent longitudinal striae, which gracefully curve so as to meet in a point at the distal extremity. In all the specimens which I saw, there is a deep depression or excavation at the base, where the fruit was attached, in all probability, to a peduncle. This fruit is not triquetrous, as the name Trigonocarpum seems to indicate, but strictly ovoidal, sometimes nearly obovoidal, having three prominent sutures joining the three valves of the epicarp. It was found in Beaver County, Pa., about three miles from the town of New Brighton, in a thick stratum of compact, but coarse grained sandstone, near the middle of the carboniferous series. Should this belong to the genus Trigonocarpum^ 1 propose calling it Trigono- carpum carbonariwm. Descriptions of new Birds of Northern Mexico* By D. N. Couch, U. S. Army. 1. CORVUS CRYPTOLEUCUS.

History, dated April 20th, 1854, acknowledging the receipt of an entire copy of the Publications of the Academy, presented in accordance with a late resolution. Also a letter from the American Philosophical Society, dated April 27, 1854, acknowledging the receipt of the last number of the Journal and of the Proceedings. May 9 th. Vice-President Bridges in the Chair. Dr Le Conte presented a paper for publication in the Proceedings, entitled " Synopsis of the Cucuiides of the United States," which was referred to Mr. Cassin, Dr. Zantzinger, and Dr. Rand. Dr. Le Conte exhibited a fragment of the jaw of a new Pachyderm from the Tertiary of Virginia, 80 or 90 miles S. W. of Alexandria, and characterised it as a new genus allied to Dicotyles. Mr. Wm. Parker Foulke asked the attention of the Academy to a Lecture by Mr. Hugh Miller, recently republished in the United States, under the title, " The Two Records, the Mosaic and the Geological ;" and made some remarks upon the importance of maintaining a careful scrutiny of the logic of the natural sciences. The cultivators of those sciences are particularly interested at this time in pre- venting any misapprehension of the results of their researches, as there is a prevailing disposition to " reconcile " these by extreme processes with the popular interpretation of certain texts of the Mosaic history. Unfinished inves- tigations of the students of nature are used as complete evidence ; and provisional generalizations are employed as fixed premises, from which are drawn conclusions very inconvenient to subsequent inquirers and writers. Thus both religion and natural science are wronged. Mr. Miller teaches that in the attempt to reconcile the two "records," there are only three periods to be accounted for by the geologist, viz., " the period of plants, the period of great sea monsters and creeping things : and the period of cattle and leasts of the field ;" that the first of these " periods " is represented by the rocks grouped under the term palceozoic, and is distinguished from the secondary and the tertiary, chiefly by its " gorgeous flora ;" and that " the geological evi- dence is so complete as to be patent to all, that the first great period of organized being was, as described in the Mosaic record, peculiarly a period of herbs and trees yielding seed after their kind." The general reader, not familiar with the details of geological arrangement, could not fail to infer from such a statement, used for such a purpose, that the palaeozoic rocks are regarded by geologists as forming one group, representative of one period which can properly be said to be distinguished as a whole by its gorgeous flora ; and that it is properly so dis- tinguished for the argument in question. It was familiar to the Academy as well as to Mr. Miller, that from the carboniferous rocks downward (backward in order of time) there have been discriminated a large number of periods differing one from another in mineral and in organic remains; and that the proportion of the carboniferous era to the whole series is small, whether we regard the thickness of its deposits or its conjectural chronology. It is only of this carboniferous era, the latest of this series, that the author's remarks could be true ; and even of this, if taken for the entire surface of the earth, it could not be truly asserted that PROCEED. ACAD. NAT. SCI. OF PHILADELPHIA, VOL. VII., HO. III. 7 70 [May, " the evidence is so complete as to be patent to all ,5 that the quantity of its vegetable products distinguishes it from the earth's surface during the era in which we live. To confound by implication all the periods termed palaeozoic, so as to apply to them as a whole what could be true, if at all, only of the carboniferous period, is a fallacious use of a generalization made for a purpose and upon a principle not properly available for the writer's argument. The high esteem in which the character of Mr. Miller is deservedly held by readers in the United States, where his writings are widely circulated ; and the respectful manner in which his interesting researches have occasioned his name to be mentioned by authors eminent in the department of geology, give to such of his writings as bear upon the biblical question, peculiar importance with reference to the com- munity at large. Mr. F- urged the duty of insisting upon the maintenance of regular methods of exposition as well as of investigation, leaving apparent inconsistencies, which are beyond our means of explanation, to be "reconciled" by our successors with the aid of larger accumulations of knowledge than we possess. The progress of science has been retarded by the assumption that every discovery must be immediately proved to be harmonious with certain other portions of our knowledge. A due regard to the sacredness of religious faith and to the natural sensitiveness of the popular mind will secure respectful caution; but it is most consistent with the acknowledged imperfection of human faculties, and at the same time most worthy of the true dignity of science, to assume that ultimately all truths will be found to agree ; and meantime, strictly adhering to the canons of evidence, to explore courageously the great field open to us. We ought espe- cially to avoid generalizations which have no sound philosophical principle, or which are framed or applied merely from a desire to appease over-zealous minds ignorant of the facts already ascertained. This obligation is stronger in propor- tion to the degree of confidence given to the teacher in any case, and also in proportion to the limitation of access to other sources of information.

Dr. Le Conte presented a paper for publication in the Proceedings, -entitled " Notes on some new Coleopterous Insects from the Collections'' 1854.] 71 of the United States and Mexican Boundary Commission." Referred to Mr. Cassin, Dr. Ruschenberger and Dr. Leidy. Dr. Le Conte also presented a paper from Mr. Charles Grirard, on a new species of Salmonidae from the Northeastern part of the United States, which was referred to Dr. Le Conte, Dr. Leidy, and Dr. Hallowell. Dr. Brinton desired to draw the attention of the Academy to a new mode which he had recently devised and practised in the preparation of anatomical specimens, several of which he exhibited. Anatomical specimens, he said, had hitherto been preserved either in the wet state, or else dried ; both plans were open to objections. If animal tissues be immersed in alcohol, or other preservative fluids, their color becomes blanched, their structure condensed, and consequently their size and shape to a certain degree modified ; and at the same time they present incon- veniences for demonstration ; whilst in the dry state, as for example, in the ordin- ary dried preparation of our cabinets, the parts are so shrunken and changed, as to convey but an imperfect idea of their primitive relations. As this shrinkage of the tissues, and the decomposition are dependent most probably upon atmospheric influence, Dr. Brinton stated that it had occurred to him some time since, that should he be able so to exclude the air, as to prevent all evaporation from taking place, he would perhaps succeed in preventing, not only the desiccation of the part, but also its decomposition. Influenced by this idea, he had commenced a series of experiments, and the suc- cess up to this time accompanying them, had led him to draw the attention of the Academy to the subject. His object being to encase hermetically every portion of his specimen, Dr. Brinton remarked that he had selected for his earlier experiments, a solution of gun cotton in ether, the ordinary collodion. This he applied by means of a brush over every portion of the external surface of his preparation. The ether quickly evaporating, a thin film of the cotton was deposited upon and in all the interstices of the tissue. This process was repeated until a layer of sufficient thickness had been obtained; successive coatings of copal and shellac varnishes were then ap- plied, so as to rentier to the preparation a certain degree of firmness and stiffness. But it soon became evident to him that collodion was not entirely suited for the generality of objects, especially for those of any considerable bulk. It possesses too slight a degree of tenacity, and is liable to become easily chipped and fissured. It was necessary, therefore, to employ some other material, and a solution of gutta-percha in benzole was selected ; this was applied in a similar manner over the object to be preserved. The pellicle left by the evapora- tion of the benzole was tenacious, dense, and could be increased to any de- sired thickness. Single layers were transparent, suiting admirably for layers of fasciae. For the encasement of the adipose tissue, collodion was still employed. The thick coating, however, which it was considered necessary to apply upon the muscular mass, was of course opaque ; hence, it became of importance to re- sort to an artificial coloring process, and for this purpose, collodion stained with the wood of the Pterocarpus santalinus, (the ordinary red saunders,) was found to answer admirably. The color resulting imitated closely that of fresh muscle. The preparation was then completed by the repeated application of copal and shellac varnishes. . Dr. Brinton explained to the Academy, that he did not present his specimens as tried and perfected preparations, for as yet they had attained the age of but some twenty days ; but merely as evidences of the application of a new principle to the preparation of anatomical objects. Time was required to test its value. Whether or not any internal decomposition could take place in consequence of the retention of a residual amount of air, Dr. Brinton could not state; but he doubted that such would be the case, to a degree sufficient to affect the contour of the specimen. Should, however, such a result ensue with regard to the speci- mens upon the table, still his experiments had shown that the process was ap- 72 [May, plicable to any tissues which had been injected or soaked with a solution of the chloride of zinc, or any other antiseptic. Here decomposition would be impossible, and the gutta-percha was certainly sufficient to prevent the shrinking consequent on evaporation. Dr. Brinton then stated that he was still experimenting, and had succeeded in procuring a colorless solution of gutta-percha in benzole and in chloroform, which would supersede the use of the collodion for the adipose matter. These transparent solutions would doubtless be applicable to the preparation of dissec- tions of the nervous system, and to pathological structures. He stated also that he thought possibly an extension of this principle might hereafter be made sub- servient to the preservation of any fresh animal tissue. Further results would be submitted to the Academy. May 23c?. Vice-President Bridges in the Chair. Letters were read From Dr. Wm. Wirtenweber, dated Prague, 30th Oct., 1853, trans- mitting several of his works, acknowledged this evening. From Dr. W. D. Hartmann, dated West Chester, Pennsylvania, May 16, 1854, acknowledging the receipt of his notice of election as a Corres- pondent. Dr. Le Conte presented a paper by Mr. C. Girard, and intended for pub- lication, entitled " A list of North American Bufonides, with diagnoses of new species." Referred to Dr. Hallowell, Dr. Leidy,and Mr. Hanson. Dr. Leidy called the attention of the members to specimens of four vertebras of a huge extinct saurian, from near Greenville, Clark Co., Arkansas. They had been kindly loaned by Mr. W. F. Roberts, an agent of the Arkansas Mining Company, who had discovered them with numerous others. Dr. L. stated, that in his late visit to St. Louis, Mr. Albert Koch, the industrious collector of fossil remains, had exhibited to him a collection of bones from the same State, and apparently of the same animal, which he was on the eve of sending to Berlin. The specimens on the table are remarkable for the robust transverse processes, which project laterally from the lower part of the body, and terminate in a large facet for the articulation of a rib. The bodies are cylindroid, and are terminated by slightly concave or nearly flat articular surfaces. The sides of the body are moderately concave, and have an acute margin at the articular surfaces. On each side of a median prominence pf the under side of the body a large vascular foramen exists. These vertebrae resemble those of the Cirnoliasaurus mag?ius, from the green sand of New Jersey, described previously in the Proceedings of the Academy,* but in that the large transverse process is cylindrical, while it is compressed cylindroid in the Arkansas saurian, and probably this latter belongs to a distinct genus, for which the name Brimosaitrus grandis is proposed. The bones are embedded in a hard limestone with mollusca, and they probably belong to the cretaceous or to the eocene period. One of the most perfect of the vertebroe presents the following measurements : Length of the body , 3| inches. Depth of articular surfaces 5 " Breadth of " 6 Length of the spinal arch ... 3 References of Plate II. Figs. 1 3, Brimosaurus grandis. : 6, Cirnoliasaurus magnus.

The posterior angles of the thorax are usually prominent, on account of the sinuosity of the sides near the base ; sometimes this sinuosity is very faint, then the posterior angles, although rectangular, are not prominent. Newman's C. punctic-ollis (Ann. Nat. Hist. 2, 398) is described as having but 6 striae on each elytron, (the 5th and 6th stria? are said to be indistinct.) Now, in some specimens, which cannot be separated from C. rufus, the fifth and sixth striae are not well marked, but in all that I have seen the seventh stria is quite obvious. As the elytra are declivous at the sides beyond the seventh stria, I think it probable that this seventh stria is constant in the gpnus, in which case there is no reason why Newman's species should not be united with C. rufus.

Abundant throughout the United States, in articles of commerce, herbaria, &c. This species, although placed by several entomologists in the present genus, has so much the form of Paramecosoma, that any person would be tempted to refer it to that genus. The first joint of the abdomen is not longer than the second, and therefore, according to Erichson's definition, it would be excluded from the family of Cryptophagides. In this essay must be included the description of a remarkable insect, of which my unique specimen is in such a bad condition, that I am unable to determine whether it should be referred to any described genus, or even to indicate its po- sition in the group ; from its specific characters, I suspect a relation with Pedi- 1854.] 79 acus, but the size of the eyes and the form of the thorax are very different.

Mr. Motschulsky informs me that the insect here described is congeneric with the Russian Physemus velutinus mentioned by him in his catalogue of the Hydrocanthares of Russia, (p. 12,) and I have acordingly adopted the name proposed by him. The insect is of small size, broadly ovate in foyn, subacute posteriorly. The antennae are longer than the head, the first four joints are thick, the second being a little shorter, the fifth and sixth are somewhat less thick, the seventh slender, as long as the sixth: the club is oval, not much broader than the first joint, and apparently solid, though with a high magni- fying power, it appears indistinctly articulated. The most remarkable char- acter is that this club is received in a deep hole, each side of the thorax, on the zipper surface, just behind the anterior angle. The feet are slender, and formed as in Linnichus. 1.

Differs from P. fusca, (which appears to be confined to the Pacific coast,) in a more distinct patch of chestnut on the crown, not merely tinged with this color; lighter throat, the rusty color extending further down, as do the attend- 120 [June, ant spots, and below these again, a large dark spot partially covered "by the feathers, and not observed in specimens of P. fusca. The middle of the breast and abdomen clear white, the rusty of crissum extending further on the belly. The bill is more rounded and shorter, the tarsus shorter, and the outer claw extends further on the middle claw. Pipilo aberti is easily distinguished by the black lores and chin, less distinct spots on the throat, and nearlj r uniform under parts. A specimen collected by Mr. Clarke, of the Mexican Boundary Survey, at the Copper Mines, appears to belong to this species. It has unfortunately lost its tail. The chestnut patch is paler. A smaller race of the same was col- lected by Lieut. Couch at Santa Catarina in Mexico. Centurus uropygialis, Baird. Head and neck all round, and the lower parts of the body brownish ash, darkest above ; a broad frontal band of dull yellowish white, (not golden.) A small quadrate patch directly on the vertex, of deep red ; rest of the upper parts banded transversely with black and white, even on the rump and upper tail coverts. Middle of the belly yellow, sides of the body along crissum, and lower tail coverts banded with black and white, like the back. Primaries black, white at the base ; secondaries with round spots on the outer web ; two central tail feathers black on the outer vane with a narrow stripe of white at the base, running for half the length of the feather near the shaft, and tapering to a point ; inner vane banded alternately with black and white ; two exterior feathers on each side banded on both vanes ; intermediate ones entirely black. Total length 9 inches, extent 16, wing 5, tails 4 l-10th. Differs from C. carolimcs in yellow belly, resembles it in character of trans- verse bands above, and markings on the tails. C. flaviventris has the middle tail feathers entirely black, and the rump and upper coverts white. C. tricolor has the middle of belly red. C. uropygialis also lacks the golden front and occiput of this and other species. Bill- Williams Fork of Colorado, New Mexico. 1351.] 121 July 4/A, 1854. Major Le Conte in the Chair.

Description of Neiu Species of Viviparous JMarine and Fresh-water Fishes, from the Bay of San Francisco, and from the Fiver and Lagoons of the Sacra- mento.* By VV. P. Gibbons, M. D. In the first paper that I read before the Academy, descriptive of these fishes, I placed them among the Labroids, on account of their corresponding in charac- ters to this family, as established by Cuvier. Prof. Agassiz, however, in a letter received from him, objects to this classification, because of the recent modifica- tions which have been made in the characteristics of the Labroidae. This question will be settled by a more intimate acquaintance with this extraordinary family, which probably comprises a large number of species yet undiscovered. The anomalous phases of animal and vegetable life in California, indicate the necessity of patient and thorough investigation before coming to final conclusions respecting the characters of new fishes. In my present descriptions, therefore, I place these fishes provisionally in the Family LABROIDAE. Genus Holconotus. Head of medium size ; body subeomprf-ssed, arched ; lips thick.

By John Lindley, Ph. D., &c," in which the diagnoses of the two families mentioned are as follows : 1854.] 129 Algales. Cellular flowerless plants, nourished through their whole surface by the medium in which they vegetate; living in water or very damp places, pro- pagated by zoospores, colored spores or tetraspores. Fungales. Cellular flowerless plants, nourished through their thallus, (spawn or mycelium.) living in air; propagated by spores, colorless or brown, and sometimes inclosed in asci ; destitute of green gonidia. Now all the entophyta in question, excepting such as are especially described as fungi, are flowerless plants, and are nourished through their whole surface by the medium in which they vegetate; aad they live in a watery liquid, (the intestinal contents,) have no mycelium, and are propagated by spores in the manner of many undoubted algae ; and, therefore, they agree with the former diagnosis, and not with the latter. They even differ in a very important char- acter from Saprolegnia, (which on page 17 of the " Vegetable Kingdom," under the name of Achlya, is placed among the algae,) which possesses a mycelium, as I have frequently observed in this curious plant growing upon dead flies, earthworms, salamanders, &c.

Head broad and large, forming a little less than the third of the whole length. Body tapering rapidly backwards. Orbits raised above the surface of the skull, which exhibits a parieto-occipital carina. Above and inwardly of nostrils a rough plate is observable. Preopercle provided with four spines, uppermost very long, extending backwards to the posterior edge of opercle ; the two next ones are small and directed obliquely downwards; the fourth, may be seen at the lower edge of that bone and directed obliquely forwards. The opercle has three spines; a stout one along the upper margin of that bone, and two small ones towards its inferior margin and directed obliquely downwards. The posterior extremity of interopercle. finally exhibits the last and smallest spine of the opercular apparatus. The isthmus is rather large. The first dorsal begins at a very short distance from the occiput, and is separated from the second by a similar small space. Its base is contained once and a half in that of the second dorsal, the po-terior rays of which, do not reach the base of the caudal. The caudal in itself is rather long. The origin of the anal is under the fourth ray of second dorsal ; the tips of its posterior rays are almost even with those of the last mentioned fin, although its base does not extend as far behind. The ventrals are long and slender; their insertion being nearly equidistant between the symphysis of lower jaw and the vent. The tips of pectorals reach a vertical line, which would intersect the second ray of second dorsal fin. D VIII. 12. A 9. C 4. 1. 5. 4. [.5. V I. 3. P 16.

Greatest length of specimens observed, about ten inches. Head forming more than the third of that length, caudal tin included. Surface of head and snout spineless. The only spines observable are situated on the preopercle ; a very stout one terminated by three conical processi directed upwards and forwards, and a small, blunt one beneath directed downwards. The origin of the first dorsal is situated in a line with the posterior cutaneous flap of the opercle and upper edge of insertion of the pectorals ; its base is about half that of the second dorsal. The caudal is subtruncated. The anal is much lower than the second dorsal and not quite as long. The insertion of ventrals is be- neath the pectorals and nearer to the snout than to the vent. The tips of pecto- rals extend to a line corresponding to the anterior ray of second dorsal, which is in advance of the vent. D VII. 17. A 16. C. 6. 1. 5. 4. 1. 7. V I. 4. P 19.

A large species, of which several speci- mens were procured. The head forms the third of the length, the caudal fin ex- cluded. A rather small and blunt spine is situated above and inwardly of the ante- rior nostril. The snout is rounded and gradually sloping anteriorly. The posterior extremity of the upper maxillary extends a little beyond the posterior rim of the eye. The preopercle is armed with two small spines only, and occasionally with the rudiments of a third. The other pieces of the opercular apparatus are spineless. A cutaneous, branching flap, similar to those of Scorpceiia, is observ- able above the posterior rim of the orbit. The first dorsal begins immediately behind the occiput, with a base almost as long as the head, being composed of eleven rays, the last sending its membrane to the anterior ray of the second dor- sal, which is one-fifth of its length longer than the anterior one. The anal is but little shorter than the anterior dorsal. The insertion of ventrals is a little nearer to the anal than to the tip of lower jaw. and are composed of five soft rays and a spine. The pectorals, composed of sixteen rays, are large and broadly developed, extending posteriorly beyond the tip of ventrals, reaching a vertical line drawn from the separation of the dorsals to the vent.

Its mouth is deeply cleft ; canine teeth exist on both jaws, rather more developed than in Chi- r?is. The vomer is possessed with similar teeth as well as the palatines, where they form a very long series. Posterior convexity of preopercle provided with small spines. Minute scattered scales on the head, cheeks and opercular appa- ratus. Branchial apertures continuous; branchiostegal rays six in number, scales very small. 9. Ophiodonelongatus, G Largest specimen observed, twelve inches long, the head forming about one fourth of that length ; the greatest depth, measured at the origin of the trunk enters seven times in the total length. The thickness is one third less than the depth. The body is gradually diminishing backwards, both in height and depth. The upper surface of the skull is slightly concave. Eyes, subcircular and quite large, their horizontal diameter being comprised five times in the length of side of the head. The posterior extremity of the upper maxillary extends beyond the posterior rim of the orbit. The anterior suborbi- tal overlaps the upper maxillary. Six or more small spines may be observed upon the posterior curve of preopercle. The upper angle of qpercle terminates in an acute processus. The subopercle is very long and stretches considerably beyond the opercle. The origin of the first dorsal is situated in advance of the spiny limb of the preopercle, at a distance of four tenths of an inch from I he occiput; it is contiguous to the second dorsal, which terminates at an inch and three tenths from the base of caudal (not from its rudimentary rays). The anal is nearly the same length with the second dorsal. The tips of pectoral ex- tend beyond the tip of ventrals. D XXVI. 22. A 23. C 7. 1. 5. 6. 1. 6. V I. 6. P 17.

This genus is intended to include such species of Atherina, in which the palate is unprovided with teeth, having besides a mugiloid fashioned mouth ; the inter- maxillaries constitute its upper arcade, exclusive of the maxillaries, which are situated behind. 12. Atherinopsis californiensis, G. Specimens measuring seven inches and a half in total length were observed ; the head forming exactly the sixth part of it. The body is very compressed, slender and very graceful. The cau- dal fin is deeply forked ; the base of anal is equal to the length of head ; the base of second dorsal is scarcely half as long as that of anal. Insertion of ven- trals equidistant between the tip of snout and posterior extremity of base of anal fin. Tip of pectorals not reaching the insertion of ventrals.

They are anteriorly rounded and pos- teriorly truncated, the margin of which, in the latter region, is ornamented by a series of tooth shaped serratures, more conspicuous upon large and somewhat dried specimens. Greyish brown above, dull buff beneath the silvery band. Fins unicolor, dull yellowish or greyish. When the scales are removed the upper part of the body is reddish brown; the lower part lighter with a silvery reflection. From San Francisco, Cal. GOBID^E. 13. Gobius gracilis, G. About three inches and a quarter in length; the body is slender, compressed and tapering. The head, which partakes of the slender aspect of the body, forms about the fourth part of the whole length. The mouth is very larsje ; its angles corresponding to a vertical line which would pass near the middle of the pupil. The eye is large and elliptical, situated near the summit of the head and its longitudinal diameter comprised a little more ti an four times in the length of side of head. The intevocular space above measures a fifteenth of an inch. The dorsal and anal are rather long. The caudal is posteriorly rounded or else convex upon its margin.

Body elongated, regularly arched on both the dorsal and ventral lines from head to posterior extremities of base of dorsal and anal fins. In specimens eight inches and a half in total length, the head is found to constitute a little less than the fourth of that dimension : the greatest depth, taken upon the middle of abdomen, does not enter three times in the length. The mouth is small ; the posterior extremity of upper maxillary not 1854.] 135 extending to the anterior rim of orbit. Eye circular : its diameter entering four times in length of side of head.

Dorsals, anal, caudal and ven- trals purplish, base of anal exhibiting a whitish stripe. Pectorals whitish or yellowish. From San Francisco, Cal. 15. Amphistichus similis, G. Among the specimens collected, there is one a female a little over four inches and a half in length, which we propose to describe as a very closely allied species to A. argenteus. There are two promi- nent characters which will enable us to distinguish between both species : in A. argenteus the posterior extremity of upper maxillary extends beyond to a vertical line which would pass through the middle of the pupil, whilst in A. similis it scarcely reaches the anterior rim of the same organ. Again, in the former, the second and third spiny rays of the anal are much longer than in the latter. The number of rays of fins is nearly the same; the anal has three and the pectorals two more soft rays in A. argenteus than in A. similis. There are also eleven spiny rays to the anterior dorsal of A. argenteus. D X. 24. A III. 25. C 2. 1. 6. 6. 1. 3. V I. 5. P 1. 24. The head is contained three times in the length, the caudal fin excluded. The eye large and circular, enters less than four times in the length of side of head by its diameter. The greatest depth is to the greatest length, as one to three. The body is very much compressed. The insertion of ventrals is in a line with the third spine of anterior dorsal, which is also the line of greatest depth. The coloration is not sufficiently preserved for comparative description. From San Francisco, Cal. 16. Amphistichus heermanni, G. A specimen of this species, a little over eight inches and a half in length, in affording one character proper to Holconotus has left us for some time in doubt as to its generic affinities. We speak of the structure of the dorsals, the anterior of which is composed of spiny rays higher than the soft ones of the second. Indeed, there is a slight depression in the line limiting these fins, corresponding to their point of junction ; but finding that such was also the case in Holconotus, that character could no longer be of any generic value. Seeing, however, that there were two rows of teeth on the lower jaw as well as on the upper, and that the lips, rather thin, were not free upon the symphysis of the lower jaw, we decided on placing it in the genus Amphis- tichus where it really belongs. The shape and size of the mouth are altogether similar to that observed in A. argenteus and A. similis. The body is very much compressed, of a short appearance, the nape promi- nently arched, the head contained about four tim^s in the total length and the greatest depth twice, the caudal fin excluded- Eye contained about four times in the length of side of head. The posterior extremity of upper maxillary hardly reaching the vertical of the anterior rim of pupil. The number of rays of the fins is the same as in A. argenteus, with an excep- tion in the first dorsal, which has ten spines, instead of eleven, as in A. similis. DX. 24. A III. 28.

There was but one specimen of this species collected, about seven inches and a half in length. General shape sub- fusiform, compressed ; back slightly convex from nape to posterior margin of 136 [August, dorsal fin. The head is subcorneal and contained exactly four times in the length, the caudal fin excluded. The mouth is comparatively large, although the posterior extremity of the intermaxillary does not quite extend to the anterior rim of the eye : the snout being prolonged, and the cleft of the mouth nearly horizontal. The eye is subcircular and its diameter contained five times and a half in the length of side of head. The anterior margin of the dorsal is nearer the end of snout than to the tip of central rays of caudal. The caudal itself is forked and participates of the slender appearance of the body. The origin of anal is situated behind the base of the dorsal, but at the same time in advance of the tip of the rays of the latter. The insertion of ventrals is situated in advance of the anterior margin of dorsal ; their tip reaching the anus. D II. 9. A II. 9. C 8. 1. 9. 8. 1. 9. V I. 9. P 16.

Shape of mouth as in Gila; angle of mouth provided with a small filiform barbel. Body fusiform and compressed. Caudal forked. Insertion of ventrals behind anterior margin of dorsal. Scales large and uniform. Lateral line below middle of flanks. This genus represents in the western waters of North America that of Gobio, to which it is intimately related. 18. Pogonichthys injEquilobus, B. and G General form very regular, sub- fusiform and compressed. Total length of specimen described, about ten inches, of which the head forms a little less than the sixth part. The eye is subcircular ; its diameter comprised about five times in the length of side of head. The mouth is of medium size; its cleft does not extend to a vertical line which would pass in advance of the orbit. A barbel, about an eighth of an inch, may be observed at the angle of the mouth. The origin of dorsal fin is equidistant between the extremity of the snout and the first rudimentary rays of the caudal. The caudal is long and deeply-forked ; its upper lobe projecting beyond the lower, although the structure of that fin is perfectly homorcercal. The anal is inserted behind the dorsal. The insertion of the ventrals is situated a little behind the origin of the dorsal, and consequently a little nearer the rudimentary rays of caudal than to extremity of snout. The pectorals are moderate. D II. 9. A II. 9. C 8. 1. 9. 8. 1. 7. V I. 9. P 17. The scales are large ; fifty-six of these may be counted in the lateral line, which, upon the abdomen, approximates more to the ventral than the dorsal outline. The upper legions of head and body are greyish brown ; the sides and abdompn yellowish. The fins partake of the color of the region of the body to which they belong. From the San Joaquin river, Cal. 19. Pogoni 'hthys symmetricus, B. and G. The specimens before us being in a rather poor state of preservation, a description of the species can hardly be drawn with accuracy. The size of the largest is about four inches and a half in total length ; the profile of body is subfusiform, very compressed, and gracefully elongated. The head constitutes the fifth of the length. The eye is large and its diameter contained less than four times in the length of side of head. The lobes of the caudal fin are symmetrical. The anterior margin of dorsal is equidis- tant between the end of snout and the extremity of central rays of the caudal. The lateral line forms a gentle curve, convex downwards, upon the middle of the abdomen, and nearer the insertion of ventrals than base of dorsal. The in- sertion of ventrals is situated in advance of the anterior margin of dorsal, a char- acter which will at once enable us to distinguish this species from P. inasquilobus .

Greatest depth, in advance of the dorsal, contained about four times in the length, which is eleven inches, and in which the head enters five times and a half. The mouth is very small ; its am>le being far from reaching the anterior margin of the orbit. The eye is circular and rather below the medium size ; its diameter being contained nearly six times in the length of side of head. Isthmus very small; branchiostesal rays three on either side. Anterior margin of dorsal equidistant between the extremity of snout and tip of central rays of caudal, which latter fin is deeply forked.

From Sacramento River, Cal. 21. Lavinia crassicauda, B. and G. The body in this species is less deep in the middle and less attenuated behind than in L. exilicavda. The peduncle of the tail is largely developed and contrasts greatly with that of the latter mentioned species. The head and mouth are proportionally larger ; the former being con- tained four times and a half in the total length ; and the cleft of the second, although not reaching the anterior ed^e of the orbit, extends, nevertheless, farther backwards than in L. exilicauda. The greatest depth is about equal to the length of head. The eye is subcircular, and its diameter contained about six times in the length of side of head. The caudal is less emarginated posteriorly, and the insertion of ventrals situated almost under the anterior margin of the dorsal. D II. 9 A II. 9. C 9. 1. 9. 8. 1. 8. V I. 9. P 17 or 18. The scales are much larger than in L. fx/licauda,and the course of the lateral line similar, being composed of about fifty-five scales. The general coloration is the same. Specimens were procured at San Francisco, in the Rio San Joaquin, and several tributaries of that basin. 22. Lavinia conformis, B. and G. Only one specimen of this species was obtained; its total length being about four inches. It is related to L. crassicav- da, having like it a much more compact tail than L. exilicauda. The general appearance of the fish is suggestive of L. crassicauda; the body is deeper and proportionally less elongated ; the eye much smaller and the scales larger. Ano- ther distinctive mark between the two species consists in the position of the vent- rals, the insertion of which in L. conformis, is situated in advance of the an- terior margin of dorsal, whilst it is placed slightly behind it in L. crassicauda.

This species is closely allied to the common herring (Clupea harengus) by its general appearance; the absence of teeth upon the palatine, the conspicuousness of the vomerine teeth (which are most so of all), and the presence of but two rows of them upon the tongue, will enable any one to draw the distinction be- tween the two species. From San Francisco, Cal. 25. Meletta C/Erulea, G. The body is slender, gracefully elongated, ten inches in total length, of which the head constitutes the fourth part, not includ- ing the caudal fin. The depth measured in advance of dorsal, stands in relation to the total length as one to six. The body tapers away backwards from the insertion of ventrals and dorsal ; in advance of these fins to the occiput its depth is sensibly the same, when the head again gradually slopes, above and below, towards the snout. The posterior extremity of the maxillary reaches a vertical line which would intersect the middle of the eye The posterior edge of oper- cular apparatus forms a uniform and rather flattened curve. The inferior branch of preopercle exhibits small radiating striae ; strias more conspicuous are observed upon the inferior and inner half of opercle. The anterior margin of dorsal is nearer the snout than to the base of caudal. The ventrals are inserted opposite the posterior half of dorsal. Caudal deeply forked ; anal long and low.

The origin of dorsal is just above the eye and terminates, as well as the anal, before reaching the base of the caudal. The eight or ten anterior rays of dorsal are higher than the following ones. The central rays of caudal are the longest. The pectorals and ventrals are small and rounded upon their margin ; the latter inserted considerably in advance of the former. D 78. A 60.

This species comes nearest to C. guttatus, of which it has the general physiognomy and structure of the fins ; but the head above is less convex, and the scales very differently imbricated. Thus, whilst in C. constellatus they constitute oblique series which may be traced in any di- rection, the same is not the case in C. guttatus. J) XX. I. 25. A 24. C 5. 1. 8. 7. 1. 4. V I. 5. P 19. The ground color is greenish grey; the body at large exhibiting indistinct, cloudy spots, and on the anterior and upper region, groups of black dots varying in number. Similar dots are scattered over the upper part and sides of head, and the pectoral fins are literally covered with them, so as to divide equally the space with the ground color which make these fins appear maculated with black and yellow. 2. Atherinopsis Californiensis, Grd. Proc, Acad. Nat. Sc. Philad. vii. 1354, p. 134. Genus PORICHTHYS, Girard. General form and external aspect similar to Batrachus, but more elongated ; its generic features will consist in the series of pores extending to the whole length of body from divers regions of the head. There are neither scales on the body nor membranous appendages on the margin of the jaws. Two short tenta- cles in advance of the nostrils. The teeth are slender and acute; those on the vomer most conspicuous. The head is smooth ; the opercle provided with one spine only. Ohs* To this genus belong : 1st. P. porosessimus {Batrachus porosissimus, Cuv. and Val.) from the coast of Brazil ; and 2d. P.porosus {Batrachus porosus, Cuv. and Val.) from Valparaiso. 3. Porichthys notatus, G. Total length about nine inches and a half, the head forming the fourth of it in excluding the caudal fin. The mouth is broadly cleft ; the posterior extremity of upper maxillary extending beyond the posterior rim of the orbit. The teeth upon the symphysis of the lower jaw are more slender and smaller than on the sides cf that bone. The smallest teeth are those of the irttermaxillaries extending almost to the whole length of these bones. The palatine teeth are a little larger posteriorly than anteriorly. The most con- spicuous ones are observed on the vomer. Two minute and inconspicuous spines constitute the anterior dorsal fin. The second dorsal is somewhat higher than the anal, and the tips of the posterior rays of both of these fins reach the base of the caudal, there being but a narrow space left separating these fins from each other. The caudal is posteriorly rounded. The pectorals are spear- shaped ; the central rays being the longest. J) II. 37. A 34. C 3. 1.5. 5. 1. 2. V~3. P 20.

This appears to be a rather small species, for, amongst numerous specimens brought home by several parties, and now before us, the largest measures less than six inches in total length. The body is slender, 142 [August, elongated and compressed, rather graceful in appearance. The head is contain- ed four times and a half in the total length. The snout is pointed, the upper jaw overlapping considerably the lower one. The mouth is proportionally large, the posterior extremity of the upper maxillary extending to a vertical line which would fall in advance of the eye. The eye itself is above the medium size, sub- circular in form, and contained about four times and a half in the length of the side of head. There exists a space between each dorsal, more considerable be- tween the second and third, than between the first and second. The anals are likewise separated by a space nearly equal to that which is observed between the second and third dorsals. The ventrals are exiguous, their second ray being prolonged into a filament. The pectorals are small. D 12. 19. 20. A 25. 22. C 5. 1. 16. 16. I. 5. V 6. P 17. Upper region yellowish ash; sides and belly silvery white.

A., for the Museum of the Smith- sonian Institution. By Charles Girard. It is praiseworthy for officers of the government, whether military or civil, when detailed upon special duties, to devote their moments of leisure in serving the cause of science. Lieut. Trowbridge, while engaged under instructions from the IT. S. Coast Survey, in making tidal observations for the use of that office, availed himself of such opportunities at his command to secure the fishes enume- rated below, and we leave it to Naturalists to decide whether his labors were at all rewarded. There are three main points whence specimens were obtained. 1st, Presidio, on the Bay of San Francisco, where Lieut. Trowbridge himself is stationed ; 2d, Monterey, on the Bay of the same name, where the same gentleman made several excursions; and, 3d, San Diego, where observations are conducted by Corporal A. Cassidy, U. S. A. PERCID^. 1. Labra.x nebulifer, G. The head which is" contained about three times in the length, the caudal fin excepted, presents a subcorneal appearance, from the fact of its bein.; rounded upon its upper region, and gradually sloping towards the snout. The anterior part of the body, from the origin of the dorsal to the occiput is continuous with the profile of the head, the middle region slightly convex. The body gradually tapers backwards; the greatest depth taken between the insertion of ventrals and origin of first dorsal, is a little less than the fourth of the entire length, including the caudal fin ; the greatest thickness measures in the same region as the depth, is a little more than the half of the latter. The body, therefore, is compressed, as usual in this genus, and the 1854.] 143 general outline subfusiform. The eye is subeircular, and its horizontal diameter contained about six times in the length of side of head. The posterior extremity of the upper maxillary extends to a vertical line intersecting the pupil. The lower jaw is the longest. The third dorsal spine is much the longest in the first dorsal fin, and higher than any of the rays constituting the second dorsal. The caudal is subemarginated posteriorly. The insertion of pectorals is placed im- mediately in advance of the origin of anterior dorsal ; the insertion of ventrals is situated immediately behind the base of pectorals. D X. 14. A III. S.

Ground color reddish brown above, yellowish beneath, upper part of body provided with large cloud-like blackish blotches. A dark vitta extends oblique- ly downwards and backwards from the lower rim of orbit to the throat, across the cheeks and branchiostegal apparatus. The fins are purplish blue, very intense on the ventrals, base of second dorsal, and space between the third and fourth spine of first dorsal. The snout is covered with small roundish spots. From Monterey, Cal. 2. Labrax clathratus, G. The profile of upper part of head is more de- pressed, and the head more acute than in L. nebidlfer. The lower jaw is more protruding, giving to the snout a pointed, instead of a rounded appearance, which it has in the preceding species. The fourth dorsal spine is the longest and equal in height to the highest rays of the second dorsal. The diameter of the eye is contained five times in the length of head. The origin of first dorsal is situated exactly opposite the base of pectorals. D X. 13. A III. 7. C 3. 1. 7. 6. 1. 2. V I. 5. P 15.

First dorsal fin very long, the first five anterior rays of which constitute an apparently distinct fin. Anal very Ions, provided anteriorly with but few spines. Dorsal and anal extending to near the caudal. Body very compressed and flattened posteriory. Caudal slender. Ventrals situated in advance of pec- torals. Lower jaw longest ; mouth moderate. Teeth small and conical. Scales very small. Lateral line arched above the pectorals. Six branchial rays. Opercular apparatus without either spines or denticulations. 3. Heterostichus rostratus, G. The head is rather small and conical, contiguous to a body anteriorly deep, tapering posteriorly, and very much flat- tened throughout. The nose is very much depressed and concave. The greatest depth measured above the pectoials, is contained five times in the entire length; the least depth is about the fourth or fifth of the greatest. The head forms a little less than the fourth of the length. The mouth is moderate, lower jaw much the longest ; and the posterior extremity of upper maxillary reaches a vertical line, which would pass in advance of the pupil. The teeth are conical, slender and exiguous. The eye is subelliptical, and its horizontal diameter con- tained seven times and a half in the length of side of head. The dorsal fin originates at a very short distance from the occiput. The five first rays consti- tuting an apparently distinct fin, subtriangular in shape, and much higher than the portion which follows, and which upon its anterior half, is higher than the posterior half. The soft dorsal is short, but high and in perfect continuity with the spiny one ; the tips of its posterior rays not reaching quite as far back as 144 [August, those of the anal, which approximate to the base of caudal. The caudal is slender and forked. The anal is very long and higher than the corresponding portion of dorsal ; it is highest posteriorly and lowest upon the middle. The base of the pectorals falls under the space between the third and fourth dorsal spines. The ventrals are inserted much in advance of the base of pectorals, immediately under the throat ; they are qaite small and slender. The pectorals themselves are of but medium development.

Ground color above yellowish brown with irregularly transverse blotches, or else interrupted, and then constituting longitudinal bands of a deeper hue. Head above deep brown; upper part of opercular apparatus exhibiting an elongated triangularly acute blotch, starting from the rim of the orbit. Sides and inferior surface of head yellowish.

A specimen of this species which lies before us, is thirty-five inches in total length, of which the head forms a little less than the fourth part. The body is stoutish, thickest upon its middle and somewhat com- pressed, the depth being about one-third more than the thickness. The mouth is moderate ; the posterior extremity of upper maxillary leaves a distance of three fourths of an inch between it and the vertical of the anterior rim of the orbit. Teeth on the intermaxillary, minute ; on the lower jaw, moderate ; on the palate, conspicuous and strong. The eye is subelliptical, its anterior rim a little nearer to the tip of lower jaw than to the posterior flap of opercular apparatus. The scales on the cheeks are smaller than upon the opercular pieces ; there are none to be seen in advance of the eye. The posterior extremity of anterior dorsal is nearly equidistant between the tip of lower jaw and the base of central rays of caudal. The latter is deeply forked. The extremity of pectorals is very far from reaching the anterior margin of first dorsal. The upper margin of both, the second dorsal and anal, is concave. D V. I. 11. A 1-9. C 4. 1. 8. 8. 1. 3.

The ground color of the upper region of head and body above the lateral line, is bluish black; whitish on the sides and yellowish on the abdomen. The scales have an argentine reflection which extends to the sides of the head and lower jaw. The lateral line is black. The membrane of the dorsal, caudal, anal and pectorals is yellowish, and their rays greyish; the ventrals are uniform yellowish. From San Diego, Cal. COTTIDiE s. Cataphracti. 5. Cottopsis parvus, G. May readily be distinguished from Cuttopsi* gulosus by a more compact and more fusiform body, a smaller head and consequently a much smaller mouth. The pectorals and ventrals are less developed, and the outline of the first dorsal is more convex. The caudal is posteriorly subtruncated. The insertion of ventrals is situated immediately behind the base of pectorals, and a little in advance of the origin of the first dorsal ; and when brought back- wards, their tip does not reach the anus. The tip of pectorals extends to a ver- tical line which would pass in advance of the origin of anal. The anal is much ovver than the second dorsal. D VIII. 21. A 15. C 5. 1. 4. 4. 1. 4. V I. 4.

The eyes, of medium size, are placed near the summit of the head ; their form is subcircular, and their horizontal diameter contained four times and a half in the length of side of head. The posterior extremity of upper maxillary reaches a vertical which would pass in advance of the pupil. Minute prickles are scattered all over the skin, more developed above the lateral line than beneath it. The lateral line, itself very conspicuous, follows the curve of the back uninterrupted to the base of caudal. Ground color yellowish brown above and on the sides; dull yellowish beneath. Sides and back with darker somewhat confluent blotches, or else groups of crowded dots resembling blotches. The pectorals, dorsals and caudal are barred ; the anal and ventrals unicolor.

The body is compressed and tapering; the head being contained about three times in the length, excluding the caudal fin. The occipital region is flattened; the inter- ocular space, convex, and the rostral distance, declive. The mouth is large : the posterior extremity of upper maxillary extends to a vertical line, which would intersect the posterior margin of the pupil. The eye is large, subcircular, and placed near the summit of the head; its horizontal diameter is contained four times in the length of the side of head. The interocular space is quite narrow. The opercular apparatus exhibits but a double spine of moderate de- velopment, situated upon the upper half of the limb of preopercle, with its point directed obliquely upwards. The caudal fin is posteriorly subrounded. The insertion of ventrals is situated under the middle of the base of pectorals. The origin of the dorsal is in advance of base of the same tins. The first dorsal is rather low, and not contiguous to the second, which is considerably higher. D IX. 17. A 11. C 2. 1. 5. 4. 1. 1. V I. 3. P 15. Oa the upper portion of dorsal region, alongside the dorsals, may be seen an elongated area covered with small pectinated scales or plates, disposed upon oblique or transverse rows. The skin is otherwise smooth, and the lateral line conspicuous, making a slight inflexion downwards upon the middle of the abdomen. Upper region of head and body deep chestnut brown, variegated on the sides with shining yellowish areola? and dots. Inferior surface of head, belly an I tail uniform yellow. Fins spotted or barred. From Monterey, Cal., and San Luis Obispo, Cal. SCORP.ENID.E s. Catapiiracti. 9. Scorp.-exa guttata, G The head has a pretty rough appearance : in the first place, the orbits seem as if emerging from the upper part of the skull, the middle line of which exhibits an obtuse groove. Three spines are observed along the upper edge of the orbit, behind which three more may be seen on either side of the occipital region and nape. Several supratympanic spines, but small ; two diverging ones, upon the body of opercle, and four upon the limb ol preopercle, the uppermost of which being much the stoutest and longest. Next we see four other spines irradiating downwards from the suborbitals, and finally the nasal bone terminates into a sharp and acute point directed upwards and slightly backwards. Intermingled with these numerous spines there are but two y 13 146 [August, pairs of small membranous and arborescent flaps, we were going to say, adorning the head, but in reality contributing to render it still more repulsive to an eye unitiated to scientific pursuits: the first pair is situated above the poste- rior part of the orbit, whilst the second occupies the inner upper edge of anterior nostril. The body is about eleven inches in total length, the head forming the third of it. The eye is large and elliptical: its horizontal diameter being com- prised nearly five times in the length of side of head. The posterior extremity of upper maxillary reaches a vertical line which would intersect the posterior rim of orbit. The second dorsal has nearly the same height as the first. The caudal is sabrounded posteriorly. The tips of posterior lays of anal are even with those of the second dorsal. The insertion of ventrals is under the base of pectorals ; they are elongated.

From Presidio, Cal. 11. Sebastes rosaceus, G. The general form of this species might at first be suggestive of S. norvegicus, were the central rays of the first dorsal not so much higher than in the latter species, giving to that fin a decided convexity. The fish is rather stout than elongated, though much compressed, the depth of body being about equal to the third of entire length, which is about fourteen inches, and nearly equal to the length of head. The profile from the anterior margin of first dorsal to the end of snout is rather depressed, whilst it tapers quite rapidly from the second dorsal backwards, the peduncle of the tail being rather detached from the general shape. The upper part of head exhibits but two small horizontal spines, whilst the preopercle has five of them, rather stout and conspicuous. The upper part of opercle has two spines, the uppermost of which is the largest. The eyes are large and subcircular, reaching the upper profile of head, in the length of which their horizontal diameter is comprised four times, once in advance the anterior rim of orbit, and twice behind its posterior rim. The mouth is broad, but the posterior extremity of upper maxillary does not extend beyond a vertical line which would intersect the centre of the pupil. The second dorsal is scarce higher than the first. The posterior margin of caudal is slightly concave. The second spine of the anal is strong and robust ; the tips of the posterior soft rays of that fin extend somewhat farther back than those of the second dorsal, but do not reach the base of the rays of the caudal. The insertion of ventrals is situated immediately behind the base of pectorals. The pectorals are very long, their tips extending beyond that of ventrals, and reaching a vertical line which would fall between the two dorsals. D XIII. 13. A III. 7, C 5. 1. 5. 5. 1. 6. V I. 5.

There exists, on the upper part of opercle, in the region occupied by the spines above alluded to, a large, elongated spot of a much deeper hue. From San Diego, Cal. 12. Sebastes fasciatus, G. The species which we propose here to charac- terize, has more of the general aspect of a Scorpceita, than of the genus to which it belongs. The body, anteriorly, is very stout and deep, the head more rounded, 1854.] 147 with its upper profile more inclined from the occiput to the snout than in the pre- ceding species. The total length of the fish is about eleven inches, of which the head forms more than the third. The reatest depth is equal to the length of head. The upper surface of the latter exhibits conspicuous spiny ridges, very acute posteriorly. Five triangular spines occupy the limb of preopercle and two the upper part of opercle. The posterior extremity of upper maxillary reaches a vertical line which would pass behind the pupil. The outline of anterior dorsal is convex and about the same height as the second. The caudal, posteriorly, is subrouuded. The tips of posterior soft rays of anal are even with the tips of posterior soft rays of second dorsal, and both fins approximate the base of caudal. The ventrals are long and their tip reaches the vent. The pectorals are broad and extend a little farther back than the ventrals, the insertion of which is situated upon a line behind their base.

The ground color is greenish sulphur yellow ; purplish black patches over the head, sides of body, and fins, in the midst of which patches appear crowded whitish spots. An area of ground color may be traced from the third and fourth dorsal spines obliquely downwards and backwards, towards the base of the caudal; in an oblique direction from the dorsal fin to the lateral line; then along the course of lateral line to the base of caudal fin. The throat is deep sulphur yellow; the inferior surface of the head and belly is spread all over with a more dull tint. From Presidio, Cal. HETEROLEPIDiE s. Cataphracti. 13. Chirus guttatus, Grd.

The head forms a little more than two sevenths of the entire length, which measures about twelve inches and a half. The body is very slender and exiguous. The head is flattened upon the occiput, and grooved between the eyes. The eye is well developed and its longitudinal di- ameter comprised about eleven times in the length of the side of head; seven times in advance of its anterior rim, and three times backwards of its posterior rim. The anterior portion of anal is more developed than the same part in dor- sal, the posterior extremity of which is but seven tenths of an inch distant from the rudimentary rays of the caudal : the anal does not extend quite as far back. The anterior margin of the latter is situated considerably in advance of the dor- sal, and its base is longer also. The insertion of ventrals is equidistant between the base of caudal fin and the centre of the pupil. The posterior margin of the caudal is emarsiinated. D 1C. A 13. C 4. 1. 7. 6. 1. 3. V 6. P 14.

This genus is framed to include such species, as, having the general fascies of Gunellus, are characterized by the total absence of ventral fins. The Gnnellua apos of Kamtschaka is to come under this heading, under the appellation of Apodichthys apos. 22. Apodichthys flavidus, G. The species referred to is between eleven and twelve inches long. Its head is anteriorly rounded and truncated, and is contained over nine times in the total length. The eye is rather small and sub- circular, contained about seven times in the length of side of head. The mouth is large, obliquely directed upwards, and the posterior extremity of the upper maxillary extends to a vertical line which would pass behind the orbit. The origin of dorsal is situated opposite the base of pectorals.

The mouth is likewise obliquely directed upwards ; but the posterior extremity of the upper maxillary extends only to a vertical line which would intersect the pupil. The origin of the dorsal is situated immediately behind the base of the pectorals: its anterior third is lower than the rest. The origin of the anal, which is much lower than the two posterior thirds of the dorsal, is much nearer the base of the pectorals than to the extremity of th* caudal.

The scales are small, but proportionally larger than in the preceding species; and the lateral line, which is very conspicuous, may be traced from the upper margin of the opercle to near the caudal ; from the opercle it ascends obliquely for a certain distance, and then follows the outline of the back, keeping much nearer the base of dorsal fin than the middle of the flanks. The anterior portion of body and head is of a uniform deep violet ; the posterior portion exhibits a somewhat brownish ground, over which is spread a violaceous tint ; the fins are all deep violet. A deep purple crescent-shaped vitta extends from either eye to the occiput. Two oblique vitta? on the sides of head, start- ing, one from the anterior, the other from the posterior half of orbit to the bran- chiostegal apparatus.

Two large specimens of this fish were received in such a precarious state of preservation that there was no possibility of keeping 1854.] 151 the whole, and accordingly the bony frame alone lies before us. The zoological characters of the species, as far as we could ascertain, differ from those of each of the species previously described ; but having mislaid the notes taken at the time of unpacking the collection, we do not feel justified in giving a diagnosis of them from recollection, and merely record the species under the above specific name.

Body slender, elongated, and much compressed, tapering posteriorly from the origin of anal. The greatest depth, measured upon the middle of the abdomen, enters five or six times in the total length. The head is subcorneal, and constitutes about the fifth of the entire length. The eye is large, subcircular, and its horizontal diameter is contained four times and a half in the length of side of head. The dorsal commences above the base of the pectorals, being quite low for about half its length, and terminating at about three quarters of an inch from the base of the caudal. The origin of the anal is opposite the eleventh ray of the dorsal, and extends a little further back; the depth of that fin is equal to the height of the portion of the dorsal opposite to it.

A large specimen of this species, collected at San Diego, Cal., contained five young ones, the total length of the largest beinu nearly three inches, and its depth equal to the third of its length. Their bodies are light reddish orange, with the peculiar longitudinal light strip?s very conspicuous. The two anterior thirds of dorsals, the anterior third of anal, and the base of ventrals exhibiting a deeper reddish orange ; the posterior portion of dorsal and of anal fins are rather yellowish. An elongated jet black spot exists near the base of the anterior portion of the soft dorsal ; the tip of ventrals is black ; the margin of the anterior dorsal fin also black. The caudal is long and truncated ; the extremities of both the dorsal and anal fins extend beyond the base of caudal as appears to be the case in the young of Rhacochilns tozotes. From Presidio and San Diego, Cal. 30. Embiotoca cassidyi, G. There is another species of Embiotoca, the young of which exhibit the same structure ol the fins as observed in those of E. lineata, 152 [August, and Rhacochilus toxotes. We have before us five immature specimens, the largest of which measures but two inches and a half, and is consequently smaller than the largest of E. live at a. They werp collected by A. Cassidy, and sent with other specimens, without mention being made whether caught freely swimming in the water, or taken by him fiom the parent hsh. At any rate they are easily distinguished from those of E. Hit eat a in possessing numerous trans- verse greyish bands more or less regular from head to tail and from dorsa to ventral line. The anterior portion of anal, the anterior edge of soft dorsal, the tip ot spines of first dorsal, and the ventrals are blackish : the remaining parts of these fins, as well as the caudal and pectorals, are yellowish. The cau- dal is slightly emarginated posteriorly. Adult specimens of this species have not yet fallen under our examination. We have not hesitated in establishing it as distinct from those already described after the careful study of the young in that family. From San Diego, Cal. 31. Holconotcjs niioooTERus, Agass. Amer Jour, of Sc. Second series, xvii. 1854, p. 368. Sixteen young were taken from ihe parent body; they are from eight-tenths of an inch to an inch long. A small vitelline sac is still to be observed at the ab- dominal region. The general form is slender and elongated. The head is deeper than the body and rounded ; the snout much less prominent than in the adult; its general outline resembling more that of an adult Amphisti chits. The vertical fins are much more developed than in the parent ; the caudal is rounded off, the central rays being the longest. The soft dorsal and anal are likewise higher and extend posteriorly to the base of the caudal if not slightly beyond it, the dor- sal at least. Coloration uniform light yellowish ; fins whitish of an extreme transparency owinu undoubtedly to their having but shortly escaped from the egg. Specimens were obtained at Presidio and San Diego, Cal. 32. HoLCONorus trowbridgii, G. This species is about the size of H. rho- doterus of which it has the general appearance. The body, however, is propor- tionally less elongated and consequently more deep. The greatest depth, measured between the origin of the first dorsal and the base of the ventrals, is contained three times in the total length, whilst the head enters in it four times and three fourths. The anterior portion of the body is superiorly very convex, and the upper surface of head sloping rapidly towards a rounded snout terminated by a very small mouth ; considerably smaller than in H. rhodoterits, whilst the teeth are much shorter than in the latter species. The eye is large and circular, and contained but three tim<--s in the length of the side of head ; the distance between the anterior rim of the orbit and the end ol the snout is less than one diameter of the eye. A line drawn vertically down from the origin of the lirst dorsal would pass immediately behind the basp of the pectorals. The base of the anal is compris<-d six times and a half in the total length of the fish, whilst in II. rhoduterns the base of the same fin enters in the length of said species but five times. The base of the ventrals is nearly equidistant between the symphy- sis of the lower jaw and the posterior extremity of the base of anal ; in II. rhu- doterus it is nearer to the snout. D IX. 13.

The fins are yellowish ; a cloudlike purplish spot at the anterior portion of anal. The posterior half of ventral is of a deep purple. Ohs. The label accompanying this species was unfortunately lost, consequently its location we are not prepared to give. 33. Holcoxotus megalops, G. This species, six inches and a half in total length, is the largest of its species, as far as observations go. The body is very much compressed and very deep upon its middle region, tapering rapidly from 1854.J 153 the origin of anal backwards. The greatest depth measured under the anterior dorsal, is contained a little more than thrice and a half in the total length. The head forms a little less than the fourth of the whole length. The cephalic region is concave. Mouth rather above the medium size, its cleft being ob- liquely directed upwards; the teeth are very exiguous ; the posterior extremity of upper maxillary does not extend beyond the vertical line of the anterior rim of orbit, owing to the oblique position of mouth. The eye is very large and cir- cular ; its diameter being contained less than three times in the length of side of the head. The anal is very Ions and low posteriorly. The caudal is forked.

Anterior part of dorsal fin gradually rising from the first to the last spine, which, however, is a little shorter than the first articulated ray. Anal very low but quite long, furnished with bifurcated rays. This genus is allied to Emhiotoca by the presence of one row of teeth only upon both the upper and lower jaws, and by the lower lip in not being free all around. The structure of the dorsal reminds us of Amphistlchus, whilst the shape of the anal is strongly suggestive of Holconotus. 31. Phankrodox furcatus, G.

The above enumerated mammalia may be considered as well ascertained and :t species. I am still uncertain whether Eucrotaphus* is distinct from iochcerus ; and have, therefore, not included it in ihe list. The specimens upon which the former genus was characterised, apparently indicate two distinct species : whereas, all the teeth which have been found of the latter, so far have indicated but one species.

The jaws are armed with a spoon-shaped plate, the edge of which is sharp and cutting. Pharingeal teeih disposed upon one single row. The general appearance of the fish is cyprinoid, and stiongly suggestive of Pimephales, the head having a rather robust appearance with a blunt snout. The mouth itself is rather small. There are no barbies or rudimentary barbies of any kind. The insertion of the ventral fins is situated opposite the anterior margin of the dorsal. The caudal is emarginate. The scales are very large. The lateral line is conspicuous, running through the middle of the flanks, slightly bent dowtiwards upon the abdomen. Cochlognathus ornatls, B. & G. Head forming two ninths of the entire length, and abruptly rounded off on the snout. Mouth proportionately small and terminal with oblique cleft. Eyes rather above the medium size ; their diameter being contained four times in the length of the side of head. Body much com- pressed, covered with large scales disposed in twelve longitudinal rows on the line of greatest depth. Lateral line inflexed downwards upon the abdomen.

I continue to retain Tritoma united with this genus, as the slight difference in form will by no means warrant their separation. The differences in the antennae cannot be considered as of greater value, since in neither of the groups are they persistent ; finally, the last joint of the maxillary palpi is more transverse in the genuine Triplax, being about three times wider than long, while in Tritoma the breadth is only double the length.

Descriptions of neiv fossil species from the fresh water Tertiary Formation of Ne- braska, collected by the North Pacific Railroad Expedition, under Gov* J J Stevens. By John Evans, M. D., and B. F. Shumard, M. D. The organic remains which form the subject of the present communication were obtained from Nebraska Territory, in the vicinity of Peno Creek, a small tributary of Teton or Little Missouri River, about ninety miles from Fort Pierre Chouteau. They occur in great profusion in thin-bedded, light gray, sili- ceous limestone, near the summit of the elevated plateaux which border the Mauvaises Terres. They consist of several species of Lymnea, one Physa, one Planorbisy the seed vessels of a species of Chara and the carapaces of a minute Cypris. These genera at once establish the lacustrine character of the deposit in which they occur. The fossils are beautifully preserved, and project in fine relief from the weathered surfaces of the limestone. Many of them have been converted into semi-transparent chalcedony. They are of considerable interest, from the fact, that the strain in which they are imbedded, repose on the tertiary marls and clays, which have yielded those magnificent collections of extinct mam- malian and chelonian remains de^ribed by Prof. J.

Shell small, depressed, discoidal, above moderately concave ; volutions about four, rounded, obtusely carinated ; below rounded, umbilicus small, exhibiting the volutions to the apex of the spire, suture distinct ; body whorl with an obtuse 1854.] 165 dorsal carina, aperture sub-trigonal, surface marked with delicate, arched striae of growth. Width, 2s lines ; height h of a line. Occurs very abundantly. Lymnea diaphana. (Nov. sp.) Shell small, oblong, ovate- conic ; whorls fine, convex, crossed by delicate lines of growth, spire short, acute at apex ; aperture oval, slightly dilated, rather larger than half the length of the shell; columella rather delicate and sinuate, umbilicus minute. Length, 2j lines ; width, 1J- lines ; length of aperture, \h lines. Very common. Lymnea Nebrascensis. (Nov. sp.) Shell ovate, sub-conic, volutions five, convex, crossed by minute, elevated lines of growth ; body whorl ventricose, more than twice the length of spire ; spire short, apex pointed, suture not deeply impressed ; lip produced in front. Length, 5 lines ; length of body whorl, 4 lines ; width about 2^ lines. All the specimens in our possession are very much compressed, and other- wise mutilated, so that the form and character of the aperture cannot be deter- mined. It is very similar to the preceding species, from which it is distinguished by its greater size and its numerous crowded striae. PHYSA SE.CALINA. (Nov. Sp.) Shell small, thin, oblong-oval ; volutions four, evenly convex, smooth or with very fine lines of growth ; aperture ovate, narrow, more than equal to the entire length of the shell ; spire short, slightly rounded at summit, suture distinct but slightly impressed. Length, 2 lines ; width, \\ lines. Only two specimens of this little shell have come under our observation, and these rather imperfect. Cypris Leidyi. (Nov. sp.) Carapace minute, reniform, vertical section sub-cordate, width of extremities nearly equal ; central and anterior portions of surface very convex, the convexi- ty diminishing towards the posterior end; ventral margin straight or very slightly concave, about one third shorter than the entire length of the valves; dorsal and lateral margins convex, encircled by a well defined, narrow groove, which ter- minates at the ventral margin ; surface covered with exceedingly minute gra- nulae. Length, I of a line ; width, \ ; thickness, 2-5th. A close examination of the slabs of fresh water limestone from the vicinity of Peno Creek, has resulted in the discovery of this pretty little crustacean. The substance of the fossil is nearly transparent chalcedony, and the valves in both specimens remain attached in their normal position.

The following brief characters are given in advance of more full descriptions, with figures, that may follow hereafter. CEPHALOPODA. 1. Nautilus. 1. Nautilus Spillmani. Shell depressed vertically, umbilicated \ last cham- ber lar^e, inflated, spreading, emarginated, flattened beneath. The depressed and inflated form of this fossil sufficiently distinguishes it from, every other species of the genus in our cretaceous rocks. Inscribed to Dr. Spillman, of Columbus, Miss. Locality, Mississippi. Dr. Spillman. 2. N. orbiculatus. Shell somewhat discoid, thick in the centre and gradually thinner towards the circumference ; last chamber very 'arge, spreading at the PROCEED. ACAD. NAT. SCI. OF PHILADELPHIA. VOL. VII. WO. V. 15 168 [September, umbilicus; siphunculus nearly central ; septa profoundly undulating, showing on the back a sharp recurved lip. This is the largest of the genus found in our rocks, being ten inches in dia- meter. It resembles quite closely N. D aniens, especially in the undulations of the septa. Locality, Alabama. 3. N. angulatus. Shell with the septa regularly curved ; emarginated ; me- dium space wide, flat, obtusely angular; siphunculus large, situated towards the inner margin of the chamber; aperture very w r ide. Readily distinguished from N. Dekayi, which it resembles, by the angles on the back, and flat median space. Locality, Mississippi. 2. Ammonites. 1. Ammonites magnificus. Shell compressed, broadly oval ; whorls rapidly decreasing in size, crossed by coarse nodose ribs ; nodes at each extremity of the ribs, the outer nodes compressed and arranged on each side of the convex median space; septa not greatly ramified, dorsal lobe deeply bifurcated. Bears some resemblance to A. Delawarensis, but is a very distinct species. Diameter tw r o feet. Locality, Pickens county, Alabama. 2. A. earinatus. Shell covered with prominent, closely arranged ribs; ribs nodose, a little undulating ; nodes in five revolving lines ; nodes on each side of the median line compressed; median line carinated ; whorls rapidly decreasing in width ; aperture ovate. From the preceding species this is distinguished by its more numerous and closely arranged ribs and numerous nodes. A cast in calcareous sand, having a portion of the siphunculus beautifully preserved. Locality, Columbus, Mississippi. Dr. Spillman. 3. A. binodosus. Shell undulating with lines of growth; nodes in two re- volving lines, equi-distant from the sides of the whorls, inner line more promi- nent ; median space narrow, flat ; aperture elliptic. This very distinct species has a considerable part of the shell remaining com- pletely silicified. The narrow, flat median space, the absence of ribs, and two distinct rows of nodes, separate this from its congeners. Locality, Vance's Ferry, Alabama. 4. A. lobata. Shell discoid, smooth, thin towards the circumference ; dorsal lobe finely serrate ; lateral lobes terminating in large bilobed cells. This fossil, of which I have only a fragment, resembles A. placenta, but is distinguished from it by the remarkable cells that terminate the lateral lobes. Locality, Noxubie county, Mississippi. Mr. Richardson. 5. A. ramosissimits. Shell remotely ribbed, slightly nodose; median line com- pressed ; septa profusely foliated, aperture oval. The fragments of this fossil in our possession are at once recognised by the very numerous subdivisions of the lateral lobes of the septa, which cover the entire surface. Locality, Sumter county, Alabama. 6. A- angustus. Shell with the whorls compressed crossed by distinct some- what nodose ribs, each terminating in a robust knob, outside of which is a series of compressed tubercles; mpdian space narrow and carinated. Locality, Columbus, Mississippi. Dr. Spillman. 3. TlTRRFLlTES. 1. T. alternatns. Shell turreted, spire dextral ; whorls angulated, lower side ornamented by two tuberculated carinas, transversely plaited ; plaits double the number of tubercles, alternately terminating in a tubercle. 1854.] 169 Two fragments of this fossil have been found. Portions of the nacreous part of the shell remain, and show distinctly the deeply foliated margins of the septa. This is the first notice of the occurrence of the genus Turrulites in the creta- ceous rocks of the United States. Locality , Noxubie county, Mississippi. L. C. Richardson, Esq. GASTEROPODA. 1.

Locality, Columbus, Mississippi. Dr. Spillman. Ostrea. 1. O. crenulata. Shell subfalcate, lower valve with closely plaited squamose ridges ; upper valve convex, with smooth plates ; ligament area long, triangu- lar; margin crenulated. Resembles the young of O. sellteformis, and having often the habit of O. equestris, being attached to branches of corals, etc., by the entire length of the lower valve. Length 1.5 in. Locality, Eufaula, Alabama. Mr. Thornton. RUDISTES. Mr. Lyell was the first to point out the existence of this curious family, in the cretaceous rocks of the United Slates. The fragments then known were referred to the genus Hippurites. From that time to the present I have endeavored, with the assistance of many friends, to collect the fragments of Rudistes, scattered over the prairie region of Alabama and Mississippi. The result has been the determination of two genera and seven species, and, what is remarkable, not a single fragment that could be rer ferred to the well marked genus Hippurites has as yet been found. Without figures it is not easy to give characteristics of the species of a family, the remains of which are so badly preserved. The following, however, may serve for the present. Radiolites, Lam. Sphcerulutes, Delam. 1. R. Ormondii. Shell, lower valve comparatively thin, long, lamellae angular; lip turned upwards at the outer circumference; ramifications of the mantle slightly impressed on the lip; cells small; outer surface ornamented with verti- cal ridges composed of the zigzag edges of the leaves composing the shell ; inner surface smooth, with a thin plate extending a short distance into the aper- ture. Distinguished by the thinness of the shell and ornamented exterior. The fluting and apparent joints of the outer surface suggest, at first sight, a frag- ment of a fossil plant. Inscribed to my friend, Dr. John Ormond, of Tuscaloosa, who discovered this interesting species. Locality, Marengo county, Alabama. 2. R. lamellosis. Shell, lower valve thick, conical, large ; lip nearly horizon- tal, or slightly depressed towards the circumference, with radiating smooth ridges, more numerous towards the outer circumference; outer edge slightly and 172 [September, abruptly turned up ; exterior surface with vertical impressed lines correspond- ing with the ridges on the lip ; cirri or ramifications of the mantle impressed, dichotomously branching ; cells towards the circumference compressed length- wise. The numerous radiating ridges on the lip are characteristic of this species. Locality , Lowndes county, Alabama. 3. R. Aimesii. Shell, lower valve large, conical, very thick ; lip slightly con- vex, with narrow, radiating depressions towards the inner circumference, outer edge slightly plaited, with obsolete concentric undulating lines ; outer surface striate. Inscribed to Dr. Aimes, of Montgomery, to whose kindness I owe this fine fossil. Locality , Alabama. 4. R. undulata. Shell, lower valve thick; lip bent slightly upwards, with dis- tant, obtuse radiating ridges, or undulations, and obsolete radiating lines ; cirri of the mantle well defined. Locality, Marengo county, Alabama. Ichthiosarcolites, Desmarest. Caprinella, d'Orb. 1. /. quadrat) gularis. Shell quadrangular, curved, irregular ; septa somewhat regular, abruptly bent downwards, and approximating in the channel on the inner surface of the shell; aperture terminating obliquely and rather abruptly. Locality, Noxubie county, Mississippi. Mr. Richardson. 2. I. loricatis. Shell, aperture somewhat oval, irregular, obtusely rounded at the base, giving the cast an imbricated appearance. Locality, Noxubie county, Mississippi. Mr. Richardson. 3. I. eornutis. Shell, aperture regularly curved, flattened on one side, septa abruptly bent downwards, and towards the concave side. Distinguished from the preceding by the more distant and regular septa, and in the greater regularity of the curvature of the shell. Locality, Noxubie county, Mississippi. Mr. Richardson. I have thought proper to restore Desmarest's uncouth name, rather than violate the rule of priority. Description of a fossil apparently indicating an extinct species of the Camel tribe. By Joseph Leidv, M.D. Mr. Henry Pratten, of New Harmony, Indiana, has sent for my inspection, and as a donation to our Academy, an interesting fossil, which be discovered in the gravel drift of Kansas territory. The specimen consists of the left intermaxillary bone, containing the fang of a tooth, and a small portion of the corresponding maxillary bone. The fang of the tooth is the portion of a transformed incisor or functional canine, like that in the Camel and Lama. The crown of the tooth was directed more outwardly than in either of the latter; but it had the same form, being laterally compressed, obtuse anteriorly and acute posteriorly. At the point of emergence from its alveolus the crown measured 61 lines antero-posteriorly and 3j lines transversely. Its enamel is thin, and appears to have been smooth. The fang is laterally compressed, conical, and measures an inch and a half in length ; and it is strongly curved backward and downward, and is almost paral- lel with the palatal margin, so that its extremity is only seven lines above the latter. The intermaxillary bone is relatively larger and more robust than in the Camel or Lama, and it is broader and more convex above. Its nasal border is "ty 1854.] 17o more obtuse and very much less inclined, so as apparently to indicate a longer snout in the extinct animal. The anterior or gingeval border is thick and rough as in other ruminants. The small portion of the maxillary bone presents the remains of an alveolus, separated from the tooth of the intermaxillary by an interval, with a curved, acute margin, an inch and three-quarters long. The great distance of this alveolus from the tooth in advance, when compared with the condition of things in the Camel and Lama, arises from the great degree of extension backward and near the palate of the fang of the first functional canine. The maxillo-intermaxillary suture, at the side of the fossil, descends, as usual, parallel with the nasal border of the intermaxillary bone, and, after reaching the palatal surface is directed in a curved line forward and inward, reaching as far as the posterior third of the position of the first tooth. From this description it is evident the fossil indicates a distinct species of the camel tribe, and as it appears generically distant from the Camel and Lama, the name of Camelops Kansanus would not be inappropriate for it.

Major Le Conte stated that having visited, during the last spring, an island on the coast of Georgia, known as Colonel's Island, he had been enabled to pro- cure from the original locality authentic specimens of Magnolia pyramidata, mentioned in Bartram Travels, p. 5. On comparison with other specimens, he is convinced that it is merely a variety ot M. grandiflora ; which varies in the 1854.] 175 form of its leaves from a regular elliptic form to ovate-lanceolate. The di- mensions of the leaves from Colonel's Island are ll inches long and 2J wide. Those from other localities are, Of the elliptic form, transverse diameter, 7 inches, " conjugate, 4 inches. " ovato-lanceolate 7i long, 3J- wide. Regular gradations may be found between these various forms. The opinion expressed by Elliot that M. pyramidata is a variety of M. auriculata is there- fore erroneous. Major Le Conte also stated, that he had been personally in- formed by Mr. Bart ram that his M. pyramidata had lanceolate leaves. October 31 st. Mr. Ord. President, in the Chair.

Two tibial diaphyses of the left side of young individuals. h. A vertebra dentata. c. A. fragment of an os calcis. d. A metacarpal and a metatarsal bone. e. An ungual phalanx. Bison Americanus? (fossilis).* a. A fragment of a cervical vertebra. Cervus Virginianus (fossilis). a. Proximal half of a tibia. b. Distal half of a tibia. e. Proximal half of a metacarpal bone. d. Proximal and distal halves of two metatarsal bones. e. Portions of two scapula?. /. Proximal portion of a first rib. g. The mutilated cranium of a doe. h. The superior portion of the cranium of a buck ; the antlers having been shed. i. Three portions of as many lower jaws of different ages. One contains the back five molars very much worn away ; a second contains the last two molars a little worn; and the third contains all the molars, but the last temporary one has not been shed, nor is the last true one protruded. All these specimens cor- respond in size with the same parts of large individuals of the existing Certnis virginianus, and have the same form ; and they probably belonged to the same species. Besides these specimens, fossil bones of a deer not larger than the Cervus virginianus have been found in association with bones of the Megalonyx, Mastodon, &c, in the vicinity of Natchez, Mississippi. In the cabinet of the Academy there are several specimens from this locality, consisting of a portion of a lower jaw, a fragment of an antler, and the posterior and inferior portions of two crania. Eqtjus Americanus, Leidy. a. The last dorsal vertebra. Tapirus. a. An inferior back molar tooth of an old individual. The crown is much worn and the fangs are long, spreading, and thickened. It is larger than in the recent Tapir americanus, and belongs to the supposed extinct species which I have designated as Tapirus Hay sit. Canis prim-Evus, Leidy. This name is proposed for a species of wolf, which I suppose to be indicated by a specimen, in Mr. Lincke's collection, of a left upper maxillary bone con- taining the posterior five molars, all of which are nearly entire except the penultimate one. The fragment, however, only differs from the corresponding part of the recent Canis lupus of Europe and its American congeners, in being rather larger (about one sixth), and in its having slight variations in several of the molar teeth. Certain naturalists may regard the fossil as an indication of a variety only of the Canis lupus, and of the correctness of such a view I shall not attempt to decide. Naturalists have not yet settled among themselves the question of how far characters of a specific value may be obtained from the skulls and teeth of many genera. Most naturalists regard the Canis lupus, of Europe, and the Canis oceidentalis and many other wolves of America as of the same species. Certainly they possess no important osteological differences, but the same may be said of the grizzly bear, the polar bear, and the brown bear, or of the horse, the ass, and the zebra, or of the lion, the tiger, and the panther, etc., etc. Those who have attempted to define a species, I think, have gene- ,p-e-[t-, - ro'piro; i / c^ / ^ ^ ^ Cj V 8

On the Incineration of Filters in Analysis. In order to burn off the filters from eertain precipitates i.i quantitative analysis, considerable pa-tienee is required and loss of time involved,, owing to the presence of salts in the pores of the filter. Fresenius, in his last edition of Quantitative Analysis, counsels patience in such cases, and to facilitate the combustion by pressing tne filter against the hot crucible by a platinum wire. I have found it advantageous, in such cases, to use oxygen gas, as is done in some of the methods for preparing ashes of plants for analysis. The results are good, and none of the contents of the crucible are lost. The phosphate of magnesia-ammonia filter is thus burned off in quite a short time, and without any loss of phosphoric acid. After the filter is car- bonized, the lid is partially removed from the upright crucible, and a tube (plati- num I use, but glass will do nearly as well,) with an orifice of one mm. in diameter, delivers oxygen gas from a small vulcanized caoutchouc bag, so slowly that it miugles with the air in the crucible and effects the combination quietly, A crucible appears to be in the worst position possible for oxidation in the manner in which it is situated in the flame, for the rising air currents are un- favorable for combustion in the bottom of the crucible, and the air which does enter is diluted with the products of combustion. Though this may be par- tially improved by an inclined position of the crucible and lid, it is not obviated , and oxygen gas seems to afford a remedy with less risk than nitrate of ammonia.* 1 have not yet found any objection to its use from practice, and pure oxygen is so readily obtained from the commercial chlorate of potassa by using the wash bottles described in my article on " organic analysis by gas," and keeps so well in vulcanized caoutchouc bags that I would recommend it to a trial. Apparatus for the Analysis of Carbonates. Both in Fresenius' late edition of Analysis and in Rose's greater work are described apparatus for the de- termination of carbonic acid by Fresenius' and Wills' process, using fine balances. About a year and a half ago I described, in the Journal of the Franklin Institute, a very convenient apparatus for this purpose, which as it appears not to have come to the notice of chemists generally, and as those of my chemical friends who have tried it have approved of it, I will here shortly describe. * Schultze (Fresenius' Anal.) proposes to burn filters and plant ashes by creating an air current over the crucible by means of a broken retort neck, j- Franklin Inst. Jour., Aug., 1854, page 107. 1854.] The accompanying figure, which is of the natural size, will explain itself; the part E B D is the drying apparatus, containing sulphuric acid and is of one piece, the tube E being melted into the flask B. In making this part of the apparatus I think it preferable to join E to A before blowing the bulb. The apparatus which I made myself in this way, and with which I experimented, re- mained sound, while of a dozen made by a professional gentleman, joining E and B after the bulb was blown, six cracked at the joint. The carbonate is placed in A with water, and C, with a wax stopper, contains hydrochloric acid in case of insoluble sulphates, or is empty when the oil of vitriol of B is employed to effect the decomposition. The tightness of the joints is ascertained and the analysis carried on as in Fresenius and Wills' appa- ratus. The lead glass apparatus which I constructed myself weighed, empty, 36 grammes, and when charged for analysis and with much sulphuric acid weighed, together with the chloride of calcium tube-hook of Oertling's balance which it fits, between 50 and 60 grammes. An apparatus of Ger- man glass, made by a glass blower, weighed, with its cork and empty, 20 grms. This apparatus unites lightness with great strength, which is at once felt on handling the apparatus, which arises from the nature of the joint of E with B, and from the construction of the decomposition flask A which allows E to be made of a piece of stout tube. In its construction it is simpler than aay that I have seen, not excepting Geissler's (Jour. f. pr., ch. LX., 35,) which has one more joint, and that a ground glass one. A being entirely separate may be washed and dried ready for a fresh analysis in a couple of minutes ; the sulphuric acid in B will generally last for two analyses, and is ver} r easily emptied and re- plenished. A small sucking tube with perforated cork fitting the capillary end of the tube D, is used to bring acid on the carbonate, to draw air through at the close of the analysis, and to fill and empty B with oil of vitriol. The joints are the firmest possible in this apparatus, and the connections easily made, owing to single tubes passing through the two cork3, which corks being very small may readily be obtained of perfect quality. I have not found any error to arise from the hygroscopic nature of the corks ; but if such be feared, it is easy to coat their outsides with sealing wax varnish. The following are the experimental results with the apparatus : About one gramme of perfectly pure (tested) carbonate of soda yielded, in 236 [December, two experiments, a per cen'age of carbonic acid 41.42 and 41.35, which differ 0.07 from each other, and the mean 41.38 differs 0.01 from the theoretical per centage 41.37, sodium being taken at 23.178. Carbonate of lime, (precipitated commercial,) which contained sulphate and iron, gave the following results, the carbonic acid being evolved by nitric: 0.G3025 and 0.61625 grammes gave a per centage of carbonic acid = 41.65 and 41.70, difference 0.05. The theory for pure carbonate of lime requires 43.88. In order to ascertain the error by evolving the carbonic acid from lime by sulphuric acid, two more experiments gave 38.79 and 39.17 carbonic acid. In order to ascertain whether the carbonic acid remaining in the flask A could be expelled with a moderate boiling and thus obviate the necessity of the air tube C, three analyses were made with pure carbonate of soda (the same used as above) which gave the following results : 0.83, 0.859 and 1.0193 grammes gave a per centuge of carbonic acid 40.93, 40.34 and 40.49. Rectification of Mr. T. A. Conrad's " Synopsis of the Family of Nuades of North America" published in the "Proceedings of the Academy of Natural Sciences of Philadelphia, February, 1853." By Isaac Lea. On my return home a few weeks since from a long absence in Europe, I found, when looking over the Proceedings of the Academy, a new Synopsis of the North American Naiades by Mr. Conrad.* Finding in it numerous errors in regard to the dates of my memoirs and the fynonomy of my species, I desire that the correction of part at least of these errors may reach the scientific public by the same channel. I think it will be difficult for anyone to understand how so many errors of dates, &c. could have been written down. I had hoped that the day had gone by among us here, when any other object than the true interests of science should have existed. It has been very painful for me to be called upon, as I am, to defend my scientific labors from an attempt to deprive me of much of that which I have won by pa- tient labor and continued assiduity for so many years, and must protest against; the recognition of the incorrect dates which I shall point out to the satisfaction, T trust, of every man of science who takes any interest in the study of this branch of Natural History. I do not mean to correct the synonomy of this Synopsis, but I trust to satisfy every one, that it can be of no value whatever where theda'es are so erroneously stated. For myself, I shall rest until I have further light on the synonomy of my Synopsis of this Family published in 1852, -which I believe will be found in the main to be correct. It certainly was my intention to do justice to every naturalist, and whenever I shall be shown not to have done so I will most will- ingly make reparation. Mr. Conrad commences his Synopsis by 6aying, " The present attempt to give a synonomy of the North American Nuiades, has originated from the absence of dates and references in Mr. Lea's memoirs. To render strict justice to every au- thor according to date of publi< ation, is not only the duty of the naturalist, but a necessity of science." (Vol. 6, page 243.) If it were true that my memoirs were without " dates and references," and the truism of the duty of naturalists to render justice was complied with by the author, there would have been no occasion for me to trouble the Academy with a rectification. He usually takes the date of the title of the Volume of the Trans- actions of the American Philosophical Societv, where the species may have been described, while the volumes published by the Society, as they are almost univer- sally by all scientific bodies, were realty issued in parts at different times and gene- rally in three parts. Thus when part first of any volume was issued, the Society distributed copies immediately to their subscribers and to all the principal socie- Vol. 6, p. 243, Feb. 8, 1853. 1854.] 237 ties in Europe and in this country ; and, when I have had in such part a memoir, 1 had two hundred and fifty copies printed for my own use, one hundred and fifty of which I at once distributed at heme and abroad where I thought they might be useful to science. When part second of the same volume may have been printed, the same process took place, and when part third was ready, it took the same course, with this addition, viz. a title page for the whole volume was printed for the convenience of those who might choose to have their three parts bound into a volume, and this title bore the date of the last part. Thus most of these copies of my descriptions with figures, may have been in the hands of the Zoologists of Europe and America for two or three years prior to the date at which Mr. Conrad has stated them as being published. In addition, he usually pays no regard to the dates of my descriptions printed in the Proceedings of the American Philosophical Society or otherwise, prior to their subsequent issue in the Transactions. Thus on the 18th August, 1843, I read a number of descrip- tions before that Society and permission was granted to me to print them at once. The following day, Aug. 19th, these descriptions were printed and circu- lated. Now Mr. Conrad in his synopsis dates these as published in 1846 !* three years aftar they were actually issued printed. The rule, however, which the author says he will adopt of taking the date of the whole volume, when the da f e of publication of each species cannot be otherwise obtained, is not always followed, for the date in the title page of Vol. 3d is 1830, while the following species described in this volume, U. occidens, U. rubiginosus, U. mulliradiaius, and U. securis, he date3 in 1832, and U. helerodon,\ in the same memoir, he dates 1833; thus species described and printed in (he same memoir, are by him often dated in different years. The question as to fixing with precision the date of discovery of a new form, has been one of anxiety and doubt among men of science. For myself I have never felt satisfied that it was judicious to make any change in the long received rule of permanently fixing the date of publication! to be that, when the paper was read before and deposited with the officers of a learned Society, with a view to printing. Receiving as authority the dates issued by individuals in publica- tions is exceedingly dangerous. There may be antedates, and these can rarely be detected. In the case of a deposit of a paper with a learned society, in- tended for publication, and a record being made of it at the time, there cannot be any probability by collusion of the officers to make a change. As much of Mr. Conrad's Synopsis involves the names and claims of Mr. Rafin- esque, it becomes necessary to say something in explanation of my having in my papers adopted but few of his names. It has been asserted that I wished to de- prive this unfortunate naturalist of the credit of his labors. This I must deny. I believe I was the very first writer who, coming into this field of inquiry, showed a desire to do him justice. When I commenced, in 1827, the series of papers which has grown since to many volumes, I did not find a single species credited to Rafiuesque by Mr. Say or Mr. Barnes; but my friends, Dr. Griffith, Mr. Hyde, Mr. Peale, Dr. Green and Mr. Stewart, all my predecessors, thought they could recognise, probably, three or four of his species. In 1831. Professors Short and ISaton, of Transylvania Medical College, Lexington, published in the Transylvania Journal of Medicine a descriptive catalogue of the Naiades then known to them t having collected quantities of them in Kentucky, Ohio, &c. As Mr. Rafiuesque had been a professor in the same college, they very naturally desired to give him all they could identify, and out of thirty-five species in their list, Mr. Rafinesque * These are U. Buckleyi, U. Buddianus, U. minor, U. amygdalus, U. fuscatus and U. negUctus. f Read before the American Phil. Soc. Mar. Gth, 1829. \ Publication does not necessarily mean printing and issuing a notice of a fact or a discovery. Dr. Webster says, that publication is a "notification either by words, writing, or printing," and Johnson defines it "the act of notifying to the wor;d." 238 [December, has but six given to him, viz: mytiloides, torulosus, metanever, torsus, iriqueler and scalenius, the first, fourth and sixth of which Mr. Conrad now rejects.* I went to the task of examination with the sincerest desire of making out as many as possible of Rafinesque's species ; and having his original work before me, went over it carefully four different times, but with nearly the same result as my predecessors. I gave it up in despair, and lost my labor ; and I think I shall show further on, that Mr. Conrad himself affords the test evidence of the utter impossibility of satisfactorily fixing Mr. Rafinesque's species. It is now thirty- four years since he published his memoirs, and for nineteen years Mr. Conrad has had the advantage of having shells labelled by, he says, Mr. Rafinesque him- self, f A single species, the TJnio triangularis Raf. of Mr. Conrad's Synopsis of 1834, with its synonyms, will convince any unprejudiced person of the impossibility of the attempt made to establish Mr. Ra6nesque's species. J Dr. Griffith, Mr. Hyde and Mr. Peale have often told me that Mr. Say would not listen for a moment to such an idea as giving any regard to his species, and the works of Mr. Say fully justify this fact by the total absence of any re- cognition of his authority for a single species, until some fourteen years after Mr. Rafinesque's publication, he was induced to make his "Synonymy of the Western, North American species of the genera Unio and Alasmodonta," recognising many of the species of Rafinesque, and denying to me a single one. The feeling of the western conchologists was almost universally against the at- tempt to introduce Rafinesque's names, and most of those who had studied these shells, and written on them, or were writing on the subject, addressed me on the occasion, in utter despair of making them out.|| The principal conchologists of Ohio, in April, 1836, agreed to form " a list to be adopted by western conchologists," and after consulting together on the sub- ject, a manuscript list was sent to me by Judge Tappan, containing 112 species of Uniones, three only of which are given to Rafinesque. In August following, they more maturely considered the subject, and agreed to the nomenclature of a list in which a single species only is credited to him, and this with a mark of doubt. In a letter to me from Prof. Kirtland when he undertook the Zoological portion of the Ohio State Survey, he says, "I am particularly pleased with your arrange- ment of the Naiades \ It is altogether preferable to anything of the kind that has ever come before the scientific public, and will bear the test of the closest scrutiny and the severest criticism." * * * "I was unwilling to complete my report on our conchology until I could avail myself of the information which it contained. I shall adopt your names and arrangement with hardly an alteration." When this important State Report came out in 1838, in the whole list of nearly one hundred species of the family JYa'iades, there were but two accredited to Rafines- que, viz : metanever and mytiloides, the latter of which Mr. Conrad does not admit as a species in his Synopsis, but now declares it to be a synonym to clavus Lam. Notwithstanding the decisions of the ablest of the western zoologists, there was still an attempt to substitute by "guessing," the names of Rafinesque. This induced *Mr. Poulson says in the preface of his translation, (Oct. 1831,) that but four of Rafinesque's species were "known by his names, either in the works of Ameri- can authors or in our collections." fThis was done some twelve years after the descriptions were published, and at a time when I believe no one in any branch of science considered him as re- liable authority. He had been, according to Dr. Binney, in a "diseased state of mind " for thirteen years. I believe no one pretends to say that the original Specimens described by Rafinesque are in existence JSee further on the numerous changes made by Mr. Conrad in the position of this name and its abandonment at last. || Dr. Kirtland, Mr. Buchanan, Dr. Ward. Dr. Hildreth, Judge Tappan, Mr. Clark and some others. See Asa Gray's account of Rafinesque's Botanical Writ- ings, (Sill. Journ., 1841,) where he says that " half his genera and species do not exist at present," and that he described in "Natural History style, twelve new species of thunder and lightning." \ Alluding to my Synopsis of the family Naiades, 1836, first edition. 1854.] 239 the members of the "Western Academy of Natural Sciences of Cincinnati," in January, 1849, to review the subject, with an intention of settling this matter of nomenclature. With that Society there could be no partialities, there could be no reason for favoritism, any more than with the Reporter of the State, or the other zoologists who had devoted so many years to the study of these interesting molluscs. They went to the task with no other object than to " render strict justice to every author." The result was published in a small work, "Catalogue of the U?iios, Alasmodontas, and Anodontas of the Ohio river and its northern tributaries, adopted by the Western Academy of Natural Sciences of Cincinnati, January, 1849." There were admitted sixty-seven distinct species, of which three 'only are ascribed to Rafinesque, U.flavus, U.flexuosus and IT. nodulatus* If I had been singular in my inability to make out Rafinesque's species and to recognise him as authority, I should not, perhaps, have ventured alone, but the exception is on the other side. If we turn to the admirable work of the late Dr. Binney, on the " Terrestrial Molluscs of the United States," and there is not a more able and judicious writer on the subject, we find that he wholly discards Mr. Raf- inesque as being worthy of any regard. He says that the papers of Rafinesque " are not deemed worthy of any consideration," (p. 36,) and further on he says that" his diseased state of mind was observed about 1818" (p. 44); and again at p. 48, he says, as the genera and species proposed by Rafinesque " are con- sidered to be destitute of authority and entirely unworthy of notice, no mention of them will be made in the text." He was in the habit of naming and describing species which he never saw, as mentioned by Major LeConte, and a very remark- able case of this kind exists in his publication of his genus Tremesia, in the same paper with the Naiades. He described it as a trivalve fresh water shell living on the rocks, near the mouth of the Ohio, like the Patellcs. He described the animal and shell, and figured them (p. 54). But it is not pretended that he ever saw either, and I doubt if there be one zoologist in the United States who believes in the existence of the thing at all. In the American Monthly Magazine, Rafinesque, in a previous notice, describes it under the information of Mr. Audubon. He does not himself pretend to have seen it. When I was in Paris, in 1832, Baron Ferussac told me that I was wrong in admitting a single species of Rafinesque's if I had any doubt myself about them. He was convinced himself that he could not identify with certainty a single spe- cies. In the Magazine de Zoologie, p. 13, he says that u he had received from him the same shells under different names, and others with the names evidently not those which were given to them in his Monography. Therefore there results inextricable difficulty for the determination of his species, to establish an exact synonymy between him and others, who since have occupied themselves with the mussels." It is true that the Baron subsequently made a catalogue in which he gave precedence to many of Rafinesque's names; but it must be remembered, that this was done under the impression that these were identified as the original specimens described by him, and not, as now understood to be the case, new labels to other specimens, some twelve or fourteen years afterwards. We have seen above that Ferussac could make nothing of the labelled specimens sent to him by Ra- finesque, " marked by his own hand," which marking Mr. Conrad assumes as definite, while in reality I do not think them entitled to the least consideration. *Stronger evidence could not be presented of the futility of the efforts made by naturalists to give Rafinesque what they could by careful examination. The earlier concholgists thought they could make out four of his species, torsus 1 my- iiloides, metanever and scalenius. Professors Short and Eaton gave him mytiloides torulosas, metanever, torsus, triqueter and scalenius. Judge Tappan, with the best disposition, gave him, metanever, verucosus and tuberadatus, but all with doubt. In the list made by the western conchologists there is but one, IT. viridis, the de- scription of which Judge Tappan says equally well applies to iris. In Dr. Kirt- land's State Report, he accredits two to Rafinesque, metanever and mytiloides, and the Western Academy of Natural Sciences give him only flavus, flexuosus and nodulaius, not one of which is given to him by the other authorities above quoted. Could anything, therefore, be more uncertain ? 240 [December, Many years ago the distinguished zoologist, Mr. Swainson, sent to me from Lon- don, for the purpose of identification, a numher of Uniones, which he had received from Rafinesque, but of which he could make nothing. The confusion of pieces of valves and names formed such a mass as utterly to defy any attempt at recogni- tion of his species. I returned them, totally unable to identify them with any satisfaction. Dr. Ward said that Rafinesque's descriptions and outline " would equally well apply to six or eight different species." These facts fully account for the difference of judgment between Mr. Say and Mr. Conrad in their Synopses, both published in this city, dated April 1834. Even they with the 'specimens be- fore them marked by Rafinesque himself, could not agree in very many cases. Mr. Say considered that caslaneus, Lea, was lecvigatus, Raf., while Mr. Conrad placed lens, Lea, as asjnonym to Icevigatus. Mr. Say makes zigzag, Lea, and do- naciformis, Lea, synonyms to nervosus, Raf., while Mr. Conrad doubts that zigzag is synonymous with nervosus, and makes do naciformis synonymous with truncatus, Raf., which (donactformis) in his appendix, the next year, he considers a distinct species, but which in the new synopsis of 1853 he placed with zigzag, as synony- mous with nervosus, Raf.! Without going further into long statements of discrepancies between Mr. Say and Mr. Conrad in regard to establishing Rafinesque's species, it will be enough to say that in the Synopsis of Mr. Say it will be found that out of sixty-one des- criptions by Rafinesque he gives him thirty-eight species, and by comparing these with the new Synopsis of Mr. Conrad, eighteen of them are more or less different in their synonymy, or are entirely dismissed from the list of species.* Not wishing to devote too much time or space to tracing out the changes of of opinion by Mr. Conrad from time to time in attempting to substantiate Ra- finesque's species, it will be sufficient to trace a single one through the various sinuosities which he has carried it to this period. I do not know how many there may be like it, but I think it ought to be sufficient to satisfy any one, that syno- nyms based on such uncertain authority ought to be most carefully scrutinized. The " synoptical table of the species of American Naiades with Synonyms," April 1834, was got up by Mr. Conrad with a view, he says, to u rectify the con- fused nomenclature of American Naiades." How successfully this has been car- ried out may be seen by tracing this only one which I have attempted to follow en- tirely through with its connections. In the list of species (p 72) Mr. Conrad sets down U. triangularis, Raf. as an established species, and adds as synonyms lateralis Raf, sintoxia Raf., pachostea Raf., mytiloides Raf, ruber Raf. and pyrami- datus Lea. Eighteen months afterwards, this u retification of confused nomen- clature, was found to require itself a rectification, and we find in an appendix dated Oct. 1835, under the caption of additions to and corrections of, the catalogue of species of American Naiades," that ruber Raf. is not a synonym to triangularis, but really a species, and that pyramidatus Lea, is a synonym to it ; also, that pachostea Raf. was erroneously placed as a synonym to triangularis Raf., it too oecoraes a type, and Cooperianus Lea, is assigned as a synonym to it. Mytiloides likewise is no longer a synonym to triangularis, but it becomes one to clavus Lam. The other three are as yet still considered synonyms to the type triangula- ris might be better to cite a few of those to show at a glance, how much dis- crepancy of opinion there is between Mr. Say and Mr. Conrad, and to show how dangerous it is to science to admit such "guessing" where nothing should be set down as certain that could not bear the test of scrutiny. Mr. Conrad says it is incrassatus Lea. ' " subangulatus Lea. " foliatus Hild. " " solidus Lea. " " striatusRaf. does not admit triangularis as a species. " " " cuneatus as a species. " " " gibbosus as a species, torulosus Raf. is not admitted by Mr. Say as a species. Mr. Conrad says it is gibbosus Raf. and perplex us Lea. Unio niger Raf. Mr " fasciolus Kaf. " ' : flexuosus Haf.

Mr. ( c< ft cc }onrs t . M ft a a a cuneatus Raf. " u it patulus Lea. - tt i( gibbosus Raf. " tt perplexus Lea. a CC 1854.] 241 ris Raf. But, in the following year, June 1836, in his " Monography of the Family Unionida" p. 41, Mr. Conrad describes and figures mytiloides Rat. as a type, and assigns to it as synonyms ruber Raf. pyramidatus Lea, and cardiacea " Say of Guerin," and in his observations on this shell, now first considered by him to be a species, he says, " this common species, since its first discovery in the Western waters, has always been known by the name we have adopted"!* After these three attempts one might reasonably conclude that the synonymy of triangularis was perfectly settled to the satisfaction of the author of the Synopsis, but such proved far from being the case. Seventeen years of further experience found Mr. liafinesque's species " marked by his own hand," did not make his own species right, and we have in Mr. Conrad's Synopsis of 1853, a remodelling of these names of the most extraordinary kind. Triangularis which in 1834 was declared to be a type with six synonyms is entirely dismissed, not recognized even as a synonym. Lateralis, which then was pronounced to be a synonym to it, has also been dis- missed. Pachostea, another of the synonyms, but which was in 1835 raised to the rank of a type, is sunk into the same oblivion. Mytiloides which had been in 1836 raised to a species, from a synonym in 1834 to triangularis, and in 1835 changed to a synonym to clavus Lam., is continued a synonym to clavus, with some entirely new companions, viz., scalenius Raf. cuneaius Raf. and modiolifor- mis Say. We find sintozia which had remained for nineteen years, during all the changes, a synonym to triangularis is now decided to be a species, and it assumes that rank without any synonym. Ruber is once more considered to be a species. It was in the Synopsis of 1834 pronounced to be a synonym to triangularis Raf. In 1835 it was considered a species, and pyramidatus Lea assigned as a synonym to it. In 1836 it was degraded to the rank of synonymy again, and had myti- loides Raf. for its type. In 1853 we find it again promoted to the rank of a spe- cies, with pyramidatus Lea, and coccineus Jay, as synonyms ! And will it be be- lieved, after all these various attempts to "rectify" what was pronounced with so much formality to be the object of the writer, and to "render strict justice to every author," that he says, in a supplementary note, on this U. triangularis Raf. in this Synopsis (p. 267) that " Mr. Poulson's cabinet contains no authentic speci- men of this species, which is one I have never identified." What must we think of such an admission? In 1834 he forms a Sjmopsis under the declaration that he has at his command the specimens marked by Rafinesque himself. In this Synopsis he declares triangularis Raf. to be a species with six synonyms. Through the course of three years he separates from these synonyms three of them, which he raises to the rank of species, and then at the end of nineteen years, he drops the important type entirely, and candidly informs us in a note that it is a species he "had never identified !" and in the same note he says that u pachostea, CUfford- iania and lateralis are also uncertain species." It will strengthen the evidence of the utter futility to attempt the establishment of Rafinesque's species, by looking at Mr. Say's Synopsis, which had the same object in view. He declares this U. triangularis Raf. to be a distinct species, and assigns to it as a synonym U. ellipsis Lea.f and he pronounced my HI tides Raf. a species which Mr. Conrad at the same time placed as a synonym to triangularis Raf.f . _ _ __ _ . 1 . * Subsequently it will be seen that this species is degraded in the synopsis of 1853 again into the ranks of synonymy. 1 believe I was the first to give it a place (1829) in the lists made to endeavor to throw light on the subject, and I continued it in the various editions of my Synopsis in 1836, 1838 and. 1852, more because a certain triangular shell was generally known to us under this name of Rafinesque's, than that his description really fitted it. f Mr. Say had previously, in his American Conchology 1831, considered U. ellip- sis Lea, as being established, and he had figured and described it as mine. X If it were necessary to have further evidence of the uncertainty of Rafin- esque's species, we might trace another of these numerous discrepancies, taking scalenius. Mr. Conrad in his Synopsis 1834 gives scalenius the rank of a species, giving as synonyms cuneaius Raf. &ndpatulus Lea. In his appendix 1835 he makes scalenius Raf. and modiobformis Say. synonyms to clavus Lam. In 1838, Mono- graphy p. 92, he describes and figures patulus Lea., making it a distinct species, and in his Synopsis 1853 he adds mytiloides to the synonym of clavus Lam., having in 1836 considered mytiloides a distinct species, but he is still not sure tha.tcunea.tu4 242 [DECEMBER, I shall be much surprised if the exposition of this species, triangularis Raf. will not satisfy all unprejudiced zoologists of the hopelessness of these attempts to es- tablish Rafinesque's species of the Naiades. We come now to by far the most important part of Mr. Conrad's Synopsis the dates. He commences in the first line of his Synopsis, with the avowed purpose, in forming it, to supply an assumed " absence of dates and references in Mr. Lea's Memoirs," and he promises to "render strict justice" to every author according to date of publication. Any one unacquainted with my memoirs, would suppose from this that some at least were without dates ; such is not the fact ; every one of tbem running through a course of twenty-five years is dated. The record of their date is in the minute book of the American Philosophical Society and the record of the day on which they were read and deposited with the Society, for publication, is printed at the. caption of every one of the numerous memoirs, put there by the officers of the Society. The day on which all these memoirs were issued printed, is not easily ascertained, and this gives Mr. Conrad a field for assigning to them erroneous dates, as we shall see in the sequel. It is a mere matter of figures, but it will be seen that many are wrongly put down in his Synopsis. During the first ten or twelve years that I was engaged in writing these memoirs, no one considered there could exist any doubt, as to an author being entitled to his discovery ; if it was communicated to a learned Society, and really was a discovery. It being is- sued, printed, afterwards, was considered a diffusion of a knowledge of it. The Society then printed no " Proceedings" to give immediate notice of such discoveries abroad. It was not until in 1838 that the "Proceedings" were commenced. After this period it was generally thought best to print in the " Proceedings" the sim- ple descriptions of the species in a memoir, and the whole, in extenso, was sub- sequently inserted in the Transactions. Mr. Conrad has declared that he will not regard the date of the reading of any such described species, and acting under this principle he cuts out a large num- ber of my names, classifying them among the synonyms. But he is by no means satisfied with this reduction. The date of a very large number is erroneous as to the time of their being actually printed and circulated, as I have mentioned in the first part of this paper, that is, by assuming the date of issuing the first part of a volume to be that, when the last part was issued, while the first part may have been circulated some years before. In order to occupy as little space as possible, I will endeavor to tabulate these errors. To take up my species in the order in which they occur in his Synopsis and correct them, seriatim, would require great space. I commence with my first memoir in 1827, and proceed chronologically to 1852. Published in memoir read before and deposit- ed with the Am. Phil. Soc, Nov. 2, 1827, and printed in Trans., Voir 3, p. 259. Distributed early in 18284 Noticed in Sil liman's Jour. Oct. 129, and the Trans, cited for 1827. Raf. is not distinct, as he says in a note that it may be a distinct species. Mr. Say in his Synopsis makes scalenius Raf. and cunealus Raf. both distinct species. *The four other species of this memoir are given by Mr. Conrad without any date. fThis may be a typographical error and intended to be 1832, the same as lan- ceolatus above it. Giving Mr. Conrad the benefit of this, it will still be found that he has dated these two species fi ve years after they were read to the Society, four years after they were printed and issued, and two years after the date of the title page of the whole volume. | A correspondent in Cincinnati, under date of April 25th, 1828, acknowledges the receipt of this paper, and comments on the descriptions and the plates, and particularly the anatomical parts.

Generally the new species of this me- moir are dated cor- rectly (in 1845) by Mr. Conrad. The tetra- ffona is one year wrong, and M. minor has no date. Tn my last Memoir read before and deposited with the American Philo- sophical Society, March 5th, 1852, there are over fifty descriptions of new species. Two of these Mr. Conrad has omitted, viz. : U. Oregonensis Lea, and U. sticcissus Lea. Twelve he inserts without date ; the remainder are dated correctly, 1852. This finishes the corrections of the numerous errors of date in Mr. Conrad's Synopsis, as regards the long series of my memoirs in the Trans. Am. Phil. Soc. It will be seen by the above tables of corrections, that he has, under his own rule of the time of issuing them printed, erroneously dated about ninety of my species. I do not pretend in this rectification to correct the synonomy of the Anodonta tetragona Lea. Dated by Mr. Conrad, 1846 * At page 245 of Mr. Conrad's Synopsis in M Proceedings," this is given as a species ; at p. 250 it is made a synonym to glans Lea. 1854.] 247 Synopsis, as I have stated before. It would require too much space and time. Those interested in the subject must jud^e between the two synopses. I have certainly seen nothing in Mr. Conrad's to induce me to change the synonomy of. mine. I shall be at all times most willing to render my own more perfect by corrections founded on fact. Mr. Conrad gives precedence to claims on various principles. Sometimes he gives the priority of manuscript names in letters or labels, to printed descrip- tions and figures, as in the case of JJnio coccineus, which I described and figured in the Trans. Am. Phil. Soc (Dec. 19, 1834). He inserts it in his Synopsis " TJnio coccineus, Hildreth, MSS." Certainly I never intended to deprive my old and excellent correspondent Dr. Hildreth of any credit due to his long and ardent services in the development of the Natural History of the Valley of the Ohio. He sent it to me with many others in June 1833. There were two shells which he thought to be new, and the names he proposed were 77. coccineus and Alasmodonta obscura. I had previously received the latter from him and named it in honor of him (Unio Hildrethianus,) and communicated it to the American Philosophical Society. I adopted his proposed name for the first, as I am always accustomed to do, if it be appropriate, and called it coccineus. I also stated that it was the name proposed in his letter to me. I put Hildrethianus among the TJniones because it belonged to a peculiar group, by form and habit, which were classed as TJniones. Mr. Conrad, while he gives the name of 77. coccineus to Hildreth, objects to my retaining the name of plicatus as Lesueur's, instead of giving it to Mr. Say as he does. It seems to me that the cases are entirely dif- ferent. Mr. Lesueur gave the shell to Mr. Say with its name plicatus, as a new species. Mr. Say considered it as only an undulated variety of his crassus, pointing out that variation, and at same time said, that, " it is most probably a distinct species, and if so, the designation proposed by its accomplished discove- rer, ' plicata,' will be an excellent one." He did not describe it, and I believe all the conchological writers of the time accredited it to Lesueur, viz. Barnes, Rafinesque, Short and Eaton, Hildreth, &c. It was, subsequently to Mr. Say's no- tice, described by Barnes in Silliman's Journal, and accredited to Lesueur Say's name following Lesueur's. It was then universally received as plicatus Lesueur, and is still known as such. Although neither he nor Mr. Say described it, it is bet- ter to retain its established authorship. If it be not retained as Lesueur's it must be given to Barnes, who was really the first to publish a description of it. The same want of stability of plan displays itself in the authorship of 77. paliatus from South Carolina. Dr. Ravenel sent me this species labelled by himself with this name. Believing that he meant to publish a description of it himself, I quoted it in myjSynopsis, first edition, 1836, accrediting it to him, and so continued it in the 2d and 3d editions. Mr. Conrad, on the contrary, accredits it to me, and refers to the page of my Synopsis where I insert the species as Rave- nel's, and he adds to this error by quoting for it the Trans. Am. Phil. Soc. vol. x. page 79, pi. 7 fig. 20 where it will not be found, but quite a different species, the TJ. poJlescens Lea, which, at p. 254 of the Proceedings, in his Synopsis, he inserts as a distinct sppcies. I never described paliatus, nor claimed it in any way. It never has been described, I believe, but having been so long known as paliatus of Ravenel, 1 hope it will be continued as such. 1 have no desire to have my name attached to any species which 1 have not been the fiist to de- scribe. Regarding the " notes " on several species at the end of Mr. Conrad's synop- sis, having long since given my opinion respecting 77. complanatus, Solander, U. obliquus Lam. and most of the others, I shall not repeat these opinions; but I am glad to see in a note on cariosns, Say, (p. 264,) that he has at last done justice to Lamarck in acknowledging his luteolus. In this note he says he followed Ferussac in referring luteolus to that species, but that his "description does not apply. It very well describes 77. siliquoideus Barnes." I stated in 1833 that, having examined Lamark's specimen of luteolus in Paris, I found it to be a true siliquoideus Bar., and therefore have ever since given luteolus priority, as I was bound to do in common justice. But notwithstanding that Lamark 248 [ [December, '* very well describes the 77. siliquoideus Barnes, 5 ' (under the name of luteolus} as Mr. Conrad states, and that I had mentioned (Trans. 1833) having seen the spe- cimen itself in Paris, still Mr. Conrad, in 1834, places luteolus Lam. as a sy- nonym to cariosus, Say; and in 1836, changing siliquoideus Bar. into a type, he says he would have adopted luteolus Lam., if Ferussac had not referred La- mark's specimen of luteolus to cariosus, Say. Thus relying more on Ferussac 's opinion (whom I found really not very well acquainted with our species) than to his own judgment on studying a description, which did apply; or, on mine, to confirm it, who had examined the original carefully. Now in 1853, he comes to the conclusion that 77. luteolus Lam. = 77. siliquoideus Bar., exactly what I stated twenty years ago in the Trans. Am. Phil. Soc. vol. 5, p. 91. The note on 77. viridis Raf. (p. 266) may be answered by saying that in de- scribing 77. Tappanianus, I did not then believe, nor do I now, that it is the shell Rafinesque had before him when he wrote his description. He does not allude to the striking peculiarity of the teeth of Tappanianus, and he says his shell is common in the Kentucky and the small rivers adjacent." The Tappanianus is supposed not to exist in the west. The reason that I did not retain the name of viridis and give it to Mr. Conrad as he suggests, was that I did not believe that he and Rafinesque described the same shell, and I did not wish to use the names of the latter.* The fact stated by Mr. Conrad, that the specimen was labelled by Rafinesque himself as the 77. viridis, and that its habitat was the Kentucky river, ought to have satisfied him that it was one of the nu- merous errors of Rafinesque. f That there is an error in the habitat or the name, there is no doubt. Mr. Say, in his Synopsis, with the advantage of comparing this specimen labelled by Rafinesque, declares it to be his cariosus ! This affords another of the very many difficulties attending the attempt to substantiate Mr. Rafinesque's species. It has been the cause of the loss of an immense deal of time among naturalists, and it would have been better for Natural History if he was entirely "considered to be destitute of authority and entirely unworthy of notice," as Dr. Binney years ago concluded. As regards the note on obliquus Lam. (p. 265), Mr. Conrad suggests that I considered undatus Bar. a synonym, because Mr. Barnes gave it with a mark of doubt. Mr. Conrad does not advert to the fact that I had seen the original spe- cimen in Paris in 1832, and that I had published my note of it on my return. In his note on 77. fasciolus Raf. (p. 267) he says that the specimen was la- belled by Rafinesque. Notwithstanding this it was not admitted by him in his Synopsis of 1834 at all ! But Mr. Say introduced it in his Synopsis with multi- radiatus Lea, as a synonym, which {multiradiatus) Mr. Conrad had admitted as a. good species. In 1836, however, Mr. Conrad in his Monography, introduced fasciolus Raf., and then degraded multiradiatus as its synonym. Now in 1853 he makes multiradiatus a synonym to ligarnentinus Lam., and fasciolus is made to appropriate subangulatus Lea, as a synonym, which was described in Trans. 1840 in vol. 8th not 10th as quoted by Mr. Conrad. I am gratified to see (p. 266) that 77. trigonus Lea, after twenty years denial, is acknowledged to be a distinct species. In Mr. Conrad's Synopsis, 1834, he made it a synonym to undatus Bar., as Mr. Say also did in his Synopsis. My own label on the specimen given by me to the Academy at the time, was su- perseded for years by Barnes's name of another shell. There never was any doubt in my own mind about it, after I had given it a proper examination. I object to Mr. Conrad's changing my name TJnio Moussonianus, named after Prof. Mousson, to Moussianus, and that of Estabroolianus, named after Prof. Es- tabrook, to Eastbrookianus , as well also Margaritana Vandenbusehiana, named after Dr. Vandenbusch, to Buschiana. * My having done so in the 77. interruptus and one or two others was entirely an oversight and unintentional. I always intended to avoid using Rafinesque's names. f In a letter from the late Dr. Ward, of Chilicothe, 1836, he says in regard to this species, " that is another of Professor Rafinesque's apocryphal tales." 1854.] 249 Some of my species seem to be entirely omitted in this Synopsis. I do not observe U. aheneus, 77. occultus, IT. Oregonensis, 77. patulus, 77. pressus, 77. suc- cissus, CT. multiplicatus (nor heros Say), Anodonta Dunlapiana nor An. glohosa. In a note on cuneatus Raf. (p. 267), Mr. Conrad says it is a form between XT. patulus and 77. clavus, but he does not place patulus Lea, in his list of species, although in his Monography in 1838 he acknowledges it with a description and figure. At page 258 Mr. Conrad gives 77. tenerus Ravenel, Lea, 1834, V. 63, 9, 2." I never described nor figured this shell, and there is no reference to it in vol. 5, Trans, at p. 63, nor is it figured in plate 9. 77. teneris Ravenel and 77. paliatus Ravenel, are most singularly erroneous in their introduction. They have both been well known under Dr. Ravenel's names by his kindly distributing them. Having himself named them when he sent them to me, I distributed duplicates at home and abroad with his names. Although he did not describe them subse- quently, as 1 supposed he would, I still retained his names in my editions of the Synopsis and quoted the authorship to him. Mr. Conrad, by not keeping to a strict rule, gives in his Synopsis one (paliattis) to me and the other {tene- rus') to Ravenel. To add to this error he refers to my memoirs for both of them, quoting the page of text and the plates for figures, where they never have ap- peared at all ! I trust that I have vindicated the dates of my species by references to the facts regarding them. This defence has cost me much time in searching for the proofs necessary to rebut the errors of this Synopsis, and 1 think it will not be denied that it is effectually done.

Descriptions of eighteen New Cretaceous and Tertiary Fossils } fyc. By T. A. Conrad. Cretaceous Species. BACULITES. Baculites annulatus. Subcylindrical, ribbed ; ribs annular, some of them robust, flattened, remote, and generally partially sulcated or bifurcated, the intermediate ribs narrower and less prominent; septa bifurcating in two long equal branches, with intermediate comparatively short segments, the foliations very acutely angulated. Locality. Dallas County. HAMITES. 1. H.larvatus. Ovate-oval, obliquely ribbed; back rounded, the opposite side truncated; ribs obsolete on the back, prominent and acute laterally, and increasing in elevation alternately towards the back, where they are truncated 263 [February, and form two series of salient angles or tubercles; intermediate rib nearly equal in size, rounded on the submargin of the back, entire. (A cast.) Locality. Dallas County. 2. H. rotundatus. Rounded ; ribs distant, acute, the intervening spaces regularly and profoundly concave; back flattened, with the ribs obsolete and three indistinct longitudinal lines. (Cast.) Locality. Dallas County. ANCYLOCERAS? D'Orbigny. A. approximans. Rounded; ribs acute, oblique, prominent, alternated or bifurcated at the larger end, where there are two distant series of remote tubercles, which are not transversely opposite each other. Locality. Arkansas. Prof. Thomas. CRIOCERAS, D'Orbigny. C. (Ammonceras) Conradi, Morton. This species was described from a single specimen found at Walnford, Ocean Co., N. J. I have since obtained another through the kindness of Miss Wain. It characterizes the lowest part of the cretaceous series. CAPRINA. C quadrata. Transverse subquadrate, three of the sides flattened, slightly furrowed in the middle. Locality. Alabama. Jos. Jones. CARDIUM. Subgenus Protocardia. Cardium Arkansense. Cordate, profoundly ventricose, inequilateral ; umbo and summit very prominent ; disk with minute radiating lines ; posterior side cuniform, extremity nearly at equal distance between beak and base. Locdlily. Arkansas. Prof. Thomas. Eocene polyp. DENDROPHYLLIA ? Subgenus Petrophyllia, Conrad. Corallum not cellular, but in layers like the coats of an onion ; branches anastomosing; central axial star having distant septa between the lamellae. D.? {Petrophyllia) Arhansensis. Corallum minutely granulated, suboval, sides faintly marked with vermicular lines; calicles round, not very prominent, unequally distributed, proximate or remote; lamellae minutely serrate. Locality. White River, Arkansas. Prof. Thomas. Madrepora vermiculosa, Con., belongs to the genus Dendrophyllia, but not to the above subgenus. Eocene onultiv aires. CHITON. 1. C. antiquics. Terminal valves subtriangular, acutely rounded at base or subangulated, punctate, and with minute radiating impressed lines. Locality. Claiborne, Alabama. This species is named in the Appendix to Morton's "Cretaceous group," but the description is now first published. 2. C. Eocenensis. Terminal valve rather acutely rounded at base ; ribs 18 or 19, rounded, unequal, a few divided by an impressed line nearly their entire length, a few divided only near the base; surface obsoletely punctate or granu- lated. Locality. Claiborne, Alabama. These two species are only known by their terminal valves, and are very rare. 1855.] 267 Miocene Species. ANOMJA, Lin. A. subcostata. Obtusely ovate from base to back; lower valve thick, with interrupted somewhat tubercular radii ; upper valve thin, radii obsolete or wanting. Height l in. Locality. Colorado Desert. Dr. Heermann. Shell silicified. OSTREA, Lin. O. Heermanni. Very irregular in form, thick, ovate and subfalcate, often dilated; lower valve shallow, the exterior very irregular, with large distant angular radiating ribs, and with pits or cavities ; cartilage pit broad and oblique ; upper valve flat or concave, with a profoundly irregular surface. Height 6 inches. Locality. Colorado Desert. Dr. Heermann. Shell silicified. MERC EN ARIA, Schum. M. perlaminosa. Obliquely-cordate, very inequilateral, with numerous, pro- minent, recurved, lamelliform, concentric ribs; lunule cordate, not deeply impressed; posterior margin truncated, direct ; within purple from the pallial impression to the base; margin finely crenulated. Locality. California. Dr. Heermann. Allied to M. Ducatellii, Con., of the New Jersey ?*Iioeene. PECTEN, Lin. P. Heermanni. Suborbicular, thin, compressed; ribs about 21, square, smooth; ears moderate in size. Locality. California. Dr. Heermann. Allied to P. eboreus of the Virginia Miocene, but very distinct.

Oval; height about two-thirds of the length; apex, central, curved towards the anterior margin; ribs 20 or 21, distant, narrow, prominent ,* interstices with each a fine line. Locality. California. Dr. Heermann. Many authors adopt Leach's name for this genus, but I suppose it was unpub- lished at the time Gray's appeared. PANDORA. P. bilirata. Oblong, very inequilateral, contracted anteriorly, convex me- dially ; posterior side with two distant carinated lines towards the hinge margin which is straight and not oblique; posterior extremity truncated. Locality. Occurs w.th the preceding. CARDITA. C. occidentalis. Subtriangular, equilateral? ventricose; ribs 15, rounded, wider than the interstices, and regularly granulated by transverse lines. Locality. Occurs with the preceding. Allied to C. , of the San Pedro recent formation, but proportionally more elevated and having more prominent granules. ASTARTE, Sow. A. Thomasii. Triangular, not ventricose, inequilateral; ribs concentric, robust, recurved ; concentric lines more or less marked, minute; towards the posterior end the ribs suddenly become obsolete; extremity truncated, nearly 268 [February, direct, or sloping inwards; inner margin crenulated ; lunule large, ovate, acute, deeply excavated. Locality. Near Mullica Hill. Prof. Thomas. TURRITELLA. T. secta. Turrited ; volutions flattened or plano-convex at the sides, with minute obsolete revolving lines, a few of which are larger than the others and remote; whorls subcarinated near the base and profoundly excavated beneath towards the suture. Locality Occurs with the preceding. Prof. Thomas. Descriptions of one Tertiary and eight New Cretaceous Fossils from Texas, in the Collection of Major Emory* By T. A. Conrad. ROSTELLITES, Conrad. Univalve, elongated, with an expanded labium, and having numerous oblique plaits on the columella. This genus is related to Apoorhais, but differs in having a plaited columella. The entire shell or cast has never been obtained, and the outline cannot be determined. Rostellites Texanus. Narrow, elongated, with a subulate spire; plaits oblique, narrow, acute, largest above, and becoming obsolete towards the base; whorls of the spire flattened on the sides. Locality. Eagle Pass. The description was made from a cast, with only traces of the shell remaining, the substance of which appears to have been thick, A large portion of the flat- tened columella remains. The cast is associated with Cardium congest um. TURRITELLA, Lam. Turritella irrorata. Slightly turrited, subulate, elongated ; whorls with four to rive fine revolving unequal beaded lines on each, and an intermediate smooth minute line. Locality. Between El Paso and Frontera ? This shell differs from T. seriatim-granulata, Roemer, in having much finer lines and tubercles, and in having a smooth line between each of the beaded ones. It is associated with Nodosaria occidentalism the very small Venus quiit- quecosta, and the little Corbula occidentalis. It is imbedded in a highly fossil- iferous, ferruginous, indurated clay, which appears to have been obtained from the same bed with Cardium Texamtm. CAPRINA. 1. Caprina planata. A fragment of one valve two feet or more in length, and another smaller fragment represented in the figure. Flattened on one side and convex on the other, a much compressed outline; the shell is very long and narrow, falcate, fibrous, and distinctly exhibiting the small septa as they occur in the genus Caprina. The cavities between the septa are lined with crystals of carbonate of lime, and the shell is imbedded in white friable limestone resembling chalk marl. Locality. Oak Creek, near Puercos. 2. C. occidentalis. Falcate; flattened on the side of the outer curve, convex on the opposite ; the other margins acutely rounded ; surface very obscurely striated transversely; substance coarsely fibrous. Locality. Near the mouth of Puercos River, Texas. A. Schott. The matrix of this shell resembles chalk marl. 1855.] 269 NEITHEA, Drouet. / Neithea occidentalism Ovato-triangular, angulated; lower valve inflated, unequally ribbed and concentrically lined, lines very fine; large ribs five, rounded and elevated; smaller ribs equal, two in number in each of the intervals between the larger ribs, which latter have on each side a raised line or fine rib, giving it a trifid character; right valve flat, subconcave. Pecten quadricostatus, var. Roemer. Kreid von Texas, p. 64, pi. 8, fig. 4. This species differs from N. guadricostata in having but two equal ribs between the larger ones, whilst that species has three corresponding ribs, and it is also proportionally a narrower or more elevated shell. There is quite as much difference between the two as between N. qnadricostata and N. quinque- costata,. MACTRA, Lin. Mactra Texana. Triangular, ventricose, subequilateral ; anterior extremity subangulated and slightly produced, much above the line of the base, which is regularly and profoundly curved; posterior margin obliquely truncated, ex- tremity angulated ; anterior margin straight and very oblique ; umbo prominent. Locality. Prairie between Laredo and Rio Grande City, Texas. This species occurs only in casts, and is placed with doubt among the cre- taceous fossils. EXOGYRA, Say. 1. E. fragosa. Orbicular, lower valve ventricose posteriorly, flattened an- teriorly ; ribs very large, prominent, irregular, some of them bifurcated ; umbo not prominent, small, flattened, inner margin rugose-striate. Differs from E. ponder osa, Roem., in its large ribs, small umbo, &c. Locality. Between El Paso and Frontera. Major Emory. 2. E. fimhriata. Upper valve.

Conrad. Melania exigua. Turrited ; volutions 8, disposed to be angulated and some- what scalariform above, cancellated, longitudinal lines wanting on the lower half of the body whorl ; columella reflected ; aperture elliptical. Length one- fifth of an inch. Locality. Colorado desert, California. Dr. Le Conte. The specimens are numerous and of a chalky whiteness, showing that they are all dead shells. Said to have been found one hundred and twenty miles distant from any stream passed in the route. 1 am indebted to Dr. Caspar Parkinson and Mr. Mactier for specimens. 270 [February, Synopsis of the Pyrochroides of the United States. By John L. Le Conte, M. D. The definition under which I include the native genera helow mentioned, some of which have been widely separated by preceeding authors, may be thus expressed. Coleoptera heteromera, capite postice coarctato, collo (Hstincto thoraci affixo; oculis emar^inatis praecipue magnis ; abdomine articulis 5 vel 6 liberis, para- pleuris parallelis; coxis anticis contiguis conicis, acetabulis postice imperfectis ; tarsis articulo penultimo saepissime calceato vel emarginato, unguibus iam ad basin dentatis, iam simplicibus, raro appendici basali elongata (sicut in Meloi- dis pluribus) instructis. Thus the group differs from Anthicidae by the emarginate eyes and paral- lel parapleural ; while dentate or appendiculate ungues are not found in that family. In Lagriariae the anterior acetabula are closed posteriorly and the coxae are small; the head too is hardly constricted. Our genera may be thus arranged : A. Collum crassum: tarsi articulo penultimo emarginato: ungues simplices : abdomen 5-articulatum.

Kentucky : a fine specimen of this species was recently given me by Mr. J. P. Wild, of Baltimore, to whom I dedicate it with great pleasure, as a slight testi- mony of my appreciation of his great energy and success in collecting similar objects. Larger than the following species. The head and thorax are very densely clothed with brownish grey hair, with scattered suberect black hairs, and are confluently punctured : the former is finely channelled between the eyes. The thorax is subcordate, not longer than wide, canaliculate, much rounded on the sides before ihe middle, with the anterior constriction distinct. The ehtra are one half wider than the thorax, densely and coarsely punctured, with short black hairs proceeding from each puncture; they are irregularly mottled with dense brownish grey pubescence, with four narrow blackish vittae on each. Beneath densely covered with grayish hair. 2. E. murinus, niger breviter nigro-hispidus, cinereo-pubescens, thorsice 1855.] 271 subcampanulato, latitudine longiore, canaliculate, elytris guttis cinereo-pubes- centibus variegatis. Long. -38.

Black, uniformily covered with ashy hair, and with scattered short suberect bristles. Head and thorax confluently punctured, channeled : the latter one third longer than wide, rounded on the sides before the middle, very slightly narrowed behind; anterior constriction moderately distinct ; elytra one half wider than the thorax, coarsely and densely punctured, variegated with small spots of more dense ashy pubescence. Although Prof. Haldeman's description is long anterior to the date at which the present genus was established, he unfortunately did not give any generic character, and I was therefore compelled to change the name given by him. 3. E. c o n s t r i c t u s , ater elongatus, cinereo-pubescens, longe griseo-his- pidus, thorace campanulato, latitudine longiore, elytris guttis cinereo-pubes- centibus variegatis. Long. 35 4. Le Conte, Ann. Lye. of New York, 5, 151. San Diego, California. Narrower than the preceding, covered both above and beneath with ashy pubescence and long erect gray hairs : head and thorax confiuenily punctured, not channeled : the latter is nearly one half longer than wide, rounded on the sides anteriorly, a little narrowed behind, with the ante- rior constriction very distinct. Elytra one half wirier than the thorax, densely and coarsely punctured, variegated with spots of denser cinereous hair. Stereopalptjs Ferte. 1. S.

La Ferte, Anthic. 5, cum tab. South Carolina, Dr. Zimmerman : the detailed description of La Ferte leaves nothing to be added : from the following species it is easily distinguished by its narrower form and canaliculate thorax. 2.

Michigan. Body dark brown, covered with fine cinereous pubescence : head and thorax confluently punctured, black: the line between the eyes faint: thorax scarcely wider than long, rounded on the sides anteriorly, then obliquely nar- rowed to the base, slightly impressed each side at the middle : anterior constric- tion short, distinct only at the sides : elytra wider than the thorax, coarsely punctured, the punctures smaller towards the tip; light yellowish brown. Feet reddish yellow : first joint of the antennae brown. 3. S. guttatus, aeneo-niger, cinereo pubescens, thorace campanulato, sub- tiliter canaliculato, latitudine vix longiore, elytris guttis cinereis variegatis. Long. # 3. Two specimens found at Fort Laramie, in Nebraska territory. Black, slightly bronzed, finely pubescent : head and thorax confluently punctured, the latter not longer than wide, rounded on the sides in front, then obliquely slightly narrowed to the base, finely canaliculate, with a slight impression each side at the middle : anterior constriction short, deep. Elytra densely and coarsely punctured, one half wider than the thorax, variegated with numerous small round spots of dense whitish hair. Although colored like the species of the preceding genus, the palpi terminate in a long cultiform joint. Macratria Newman. Macrarthria Er. Maerarthrius Ferte. The reason for chaiging tha oiiginal name proposed for this genus rs not 07<> i [February, obvious ; it has a meaning, and undoubtedly should not be altered so as to give it a different meaning, either for the sake of uniformity of termination (!) or for any other reason whatsoever, unless it can be shown to have been previously occupied. 1.

Body covered with very dense serice- ous yellowish hair. Head finely punctured, slightly convex, narrowed behind the eyes, and subtruncate : mouth and oral organs yellow. Antennae with the sec- ond joint scarcely longer than the third : the following to the 8th are equal ; 9th and 10th fuscous, pale at the tip, nearly as long as the two preceding united: thorax very little wider than the head, one half longer than wide, elliptical, margined posteriorly, finely scabrous. Elytra striate with fine punctures : interstices very finely scabrous. Legs varying from yellow to piceous ; the anterior pair usually paler. The male has the 5th segment of the abdomen truncate, whereby the 6th becomes visible. In the female the 2nd segment is impressed transversely each side. In both sexes the first segment is conspicuously longer. 2. M. confusa, atra minus dense cinereo-pubescens, thorace elongato-ovato, capite non latiore, elytris vix seriat impunctatis, antennarum articulis 3 ultimis elongatis subaequalibus. Long. 18. Two males. Georgia. Darker colored than the preceding, with less dense pubescence. Head finely and sparsely punctured, rounded posteriorly, with the occipital impression longer than in M. murina. Mouth and its organs yellow ; antennee with the 2nd joint scarcely shorter than the 3rd, 37 equal, 8th fuscous, a little shorter than the 7th ; 9 11 fuscous, nearly twice as long as the 7th and Sth united, nearly equal, the 11th being a little longer. Thorax densely sca- brous, not wider than the head, nearly twice as long as wide, disc subelliptical, a little narrowed behind, where it is margined. Elytra with punctures arranged in indistinct series, interstices scarcely scabrous or punctured. Feet piceous; base of anterior thighs rufous. First segment of abdomen hardly elongated. The discovery of this second species within our territory seems to confirm the opinion of Ferte, that M. linearis Neivman, (Entom. Mag. 4, 377,) is dis- tinct from M. murina, though the great carelessness with which Newman's de- scriptions were made, should prevent us from placing reliance on them, in the absence of any corroborating circumstances. Newman's figure does not show the very strong basal margin of the thorax which exists in all the species of the genus, and where a character so evident has been omitted, we are prepared to expect any inaccuracy whatever, both in the outline and details of the figure.

Long. "46. Femina, oculis mediocribus, bene discretis, antennis serratis, extrorsum brevi- ter pectinatis, ramis praecipue articulis brevioribus. Mas latet. One specimen from Lake Superior. Differs from the preceding by the more distant eyes, the broader thorax and the more densely punctured elytra ; the joints of the antennae, from the 3d to the 6th are triangular, and the following are gradually more and more produced at the extremity. In D. concolor, the 6th joint is provided with a branch nearly as long as the seventh joint. 4. Pogonocerus ephemeroides Mann. Bull. Mosc. 1852, 348. Russian America ; unknown to me. Nematopltis Lee. Caput longe pone oculos subito constrictum, collo brevi crasso : palpi maxillares articulo ultimo ovali truncato, praecedente longiore ; labiales breves articulo ultimo ovali truncato, ligula emarginata ; mandibular apice bicuspidatae. Anten- nae fere filiformes, articulo 2ndo parvo, 3io 5to sequentibusque subaequalibus, 4to contiguis paulo longiore. Thorax capiti aequalis transversus, lateribus subangu- latim rotundatus; elytra thorace latiora parallela convexa, humeris prominulis, apice rotundata. Pedes tenues, tarsi elongati filiformes, ungues basi dilatati, at hand dentati, singulus appendice inferiore ungui ipsi fere aequali acuta apice incurva instructi, paranychio parvo distincto. 1. N. collaris, niger, capite opaco, punctulato canaliculato, thorace convexo rufo parce punctulato, canaliculato pone medium late excavato, transverso lateri- bus subangulato, elytris confertim rugose punctatis, lineis utrinque tribus obsoletis, ore flavo, palpis maxillaribus pedibusque piceis, artubus pallidioribus. Long. 35. Mas segmento ventrali abdominis quinto late ernarginato, sexto laevi nitido apice truncato. Femina latet. One specimen, Ann Harbor, Michigan. The form is like that of Eurygenius. 76 [February, Xylophilus Eonelli. In this genus the third joint of all the tarsi is lobed beneath, and the fourth joint of the two anterior pairs is very small, and received upon the third. The proper place is still not well determined: among the Anthicides it cannot remain on account of the emarginate eyes. 1. X.

Although by the curious structure of the antennae of the male this beautiful species differs from all the others below described, I can find no characters sufficient to cause it to be separated as a genus. The feet vary in color, being sometimes yellow, with only the posterior thighs fuscous: the antennas of the female are yellow; the bands of the elytra are sometimes confluent, so that the elytra appear black with yellow spots. The head is wider than the thorax, and the elytra are elon- gate parallel, truncate at base, and nearly twice as wide as the thorax. 2.

Long. -08. One specimen found in Habersham county, Georgia. The two rounded yel- low spots before the middle of each elytron seem inclined to coalesce into a transverse fascia. The punctures of the elytra are most distant towards the tip. 3.

The antenna?, as in the preceding, are gradually thickened externally, the joints from the 3d to the 10th gradually broader, the outer ones being transverse : the 11th is larger, ovoid, and acute at tip. The transverse black spot of the elytra is sometimes broken into two rounded dots. 6.
