SRARY IVERSITY OP kLIFORNIA J ELEY ITY Of >RNIA SYNOPSIS OF THE MOLLUSCA OF THE CRETACEOUS FORMATION, Including the Geographical and Stratigraphical Range and Synonymy, BY WILLIAM M. GABB. MARCH, 1861. PREFACE. IN September 1859, I published in the Proceedings of the Aca- demy of Natural Sciences of Philadelphia, a u Catalogue of the In- vertebrate Fossils of the United States." Having, since that time, been repeatedly requested to prepare a supplement, with the additions that have been made to the subject, and such corrections as I may have found necessary, I have preferred going over the whole of the formation, bringing it up to the year 1860, since the latest work of the kind only extends to 1850. My former catalogue was at first prepared for my own use only and afterwards published at the advice of some of my friends. Not be- ing intended originally for general use, and having been compiled during a press of other engagements, it was necessarily imperfect in many particulars. In the present paper I have endeavored to remedy these defects. Having access, in the collection of the Academy, to all the known types of Dr. Morton's, and a large number of Mr. Conrad's species, I am happily able to settle some points which have long been in doubt. Thus, the original specimens from which Dr. Morton described the species, Inoceramus Barabini, I find belong, as has long been suspected, to two very distinct species : one is probably I. prollematicus, Schlt. ; the other will have to retain the name /. Barabini. The types of Clypeaster geometricus, and C. florealiSj both very badly figured in the " Synopsis," and with scarcely a gene- ric description, still exist in the collection. The first is probably, as Agassiz, in his Catalogue Raisonne considered it, a Pygurus, although being but an imperfect cast, there is yet some uncertainty. The latter is not a Favjasia as considered by d'Orbigny and is a true Catsidnlns. 1 PALEONTOLOGY Again, by a comparison with the types (the only true resort in case of a dispute) I have ascertained the relations of Gryphaca Pitchcrii and Marcou's G. dilatata var. Tucumcarii. (See Proc. Acad. Feb. 12, 1861.) In preparing the synonymy of the foreign species, I have placed most confidence in special monographs, preferring in all cases to defer to the opinions of such authors as have the reputation of being most reliable. As to the American species, in addition to my own acquaintance with the subject, I have received much valuable assistance from my friends, Messrs. Conrad and Meek, both in conversation and by means of their numerous papers, more especially from the excellent catalogue of the species from Nebraska, recently published by the latter gentle- man in connection with Dr. Hayden. For convenience, I have used many abbreviations, a list of which is given below. When two or three numbers follow a reference, un- less otherwise stated, the first designates the page ; the second, the plate; and the rest the figures, thus: " Con. Jour. Acad. v. ii, 275, 24, 3," means Conrad, Journal of the Academy, volume 2, page 275, plate 24, figure 3. I have spared no labor to make this the most complete paper of the kind ever yet published, and to that end have gone over the en- tire subject anew; still a work like this must almost necessarily have some imperfections, spite the utmost vigilance of the author. I shall therefore feel myself under many obligations to any one who may take the pains to point out to me any defects, and I shall endeavor at a suitable time to correct them. W. M. G.

I have frequently examined the type of the genus, which is also Morton's type of his species, and although, at the extremity of the frag- ment there is a slight deflection, it always appeared to me to be only a thickened lip or rib, such as occurs at intervals on other species in this family. The chan- nel for receiving the older or smaller arm of the shell, is so deep as to render a section across the mouth crescentic. *' See note under APTYCHUS. Cephalapoda. g5 Trigonellites.

They were in the collection of the Academy together. Morton's species (the type of which is in the Academy's museum), is a true Delphinula, and not, as d'Orbigny thinks (Prod. vol. ii, p. 223), a Turbo. My species, on the contrary, is a Straparollus.

C. * It is with considerable reluctance that I propose a new genus in this family ,- but I am obliged either to do so, or suggest a modification of the characters of the genus Fusus as now understood. There exists a group of shells in the creta- ceous formation, of which Fusns longirostris, and F. trivolvas, may be taken as the types. The species of this group have been referred to various genera, but they all agree in possessing the general characters of Fusus, but with a very low spire, patulous body, whorl, and long, straight, slender canal ; in short, they have nearly the form of the genus TUDICLA or HAUSTELLUM, but have no folds, plates, or teeth on the columella. I have never seen the outer lip, but judging from casty and figures, I believe it to be plain. These shells cannot be referred to TUDICLA, FASCIOLARIA, or BUSYCON, because of the plain columella. The spire is very low, and as now understood the spire of Fusus is as long as the aperture. They resemble the genus PAPILLINA, Conrad, of which P. papillata, Con. (Fusns id.) is the type, but that genus has a fold on the columella like BUSYCON. PYRULA is un- tenable ; the umbilicus being entirely absent they cannot be referred to RAPA, even were the canal short. In view of these considerations, I propose the gene- ric name PERISSOLAX (/repioTro?, excessive, and wXa, furrow or canal), prefer- ring to separate the species from Fusus, rather than dispute the high authority of H. and A. Adams, and others, who maintain that the length of the spire in that genus is of generic value. This genus seems to be peculiar to the upper members of the cretaceous forma- tion, unless the recent species, Pyrula coarctata, Sow., may prove to belong to Gasteropoda. @7 Perissolax.

This is the only species outside of the limits of the chalk, with which I am acquainted, that seems even closely related to it. Four of the species are found in the upper chalk of North America ; the re- maining three are from a deposit of the same age in Chili, and they are, in both cases, associated with species of PCGNELLUS, another chalk genus. The characteristic markings are revolving ribs or lines, though some of the spe- cies are plain, with subangular whorls. This appears to be the case both with P trivolva and P. longirostris. * "Petite espece bein plus courte que le Ph. supracretacea." This is all the description given.

The Academy of Natural Sciences has all the known types of the Synopsis, and the only specimen in the Academy's museum resembling the figure is an undoubted cast of that species. Should it prove a distinct species, it is exceedingly rare, since I have never met with it among thousands of cretaceous fossils. Conchifera. JQ5 Cardita. fenestrata, Forbes, Sp. (Venus), d'Orb.

I shall therefore quote his note at length. " Malgre 1'avis plusieurs fois exprime des conchyliologistes nous pensons qu'il est indispensable, au moins pour les besoins de la geognosie, deconserver les Exo- gyres, si ce n'est comme genre, au moins comme coupe tres naturelle. Le carac- tere d'avoir constamment le crochet plus ou moins spirale, regulier et porte tout d'un cote sur la valve inferieure, nous parait du reste legitimer suffisamment cette separation, et je pourrais citer beaucoup de generes etablis sur des diffe- rences, certes, bien moins importantes. " Personne peut-etre n'a plus vu et manie d'Exogyres que moi. Des circon- stances favorables m'ont permis d'etudier des gites ou diverses especes se trou- vaient en nombre immense, offrant toutes les varietes possibles d'age et de forme, et jamais je n'ai vu un seule de ces ostracees passer aux veritables huitres.

My own observation, true it has been on a much more limited scale than that claimed above, accords with this in all but one individual instance. Morton's type of Ostrea torosa is an E. costata, very much deformed and with almost paral- lel sides, a true oyster in form, but the beak is imperfect, and were it present, it might in its young state have shown a spiral tendency. There can be no doubt of its being the common species of Exogyra of New Jersey, since it has the most typical form of surface-markings and all the other characters. It is an unique example, and being a monstrosity, can have no weight as testimony to conflict with M. Leymerie's opinion. Conchifera. Exogyra. laeviuscula, Roem. Kreid. Tex. 70, 9, 3. Texas.

If we acknowledge the above species to be sinuata, then E. costata is only a variety of the same species, for I have seen every intermediate form be- tween this and the closely costate variety. f For remarks on G.

One very much mutilated fragment I have referred, doubtfully, to this species. It is a curious fact that there should be such a scarcity, even of individuals, when beds of the same age in other parts of the United States teem with them. t Tuomey says that this species is the same as the form of I. Barabini, which I refer above to I. problematicus ? It may possibly be distinct, but I am not prepared to express an opinion, having seen only the one specimen of Morton's, which is a fragment.

The beds of New Jersey (except perhaps the leaf bed which appears to correspond to No. 1), and of the Southern States east of the Mississippi, are all above No. 3, while in Texas, Arkansas, and Indian Territory, the lower deposits are found. 17 Conchifera. \ 30 Inoceramus. salaebrosus, Tuomey, 1855, Proc.

They form a group to which Drouet ga.ve the name Neithea. They have the following distin- guishing characters, and appear to be peculiar to the cretaceous formation : the lower valve convex, upper valve flat or more generally concave, and with about six large ribs and several smaller intermediate ones. The large ribs give the outline a somewhat angular form ; this last character is never seen in Janira. Conchifera 132 Janira. Dutemplei, d'Orb. (N.), P. F. 646, 447, 8-11. Faucignyana, P. & R.

It was, however, very much wider in its range than when, in 1799, Lamarck restricted it to the true Madras. But, in 1778, Hum- phreys applied the name TRIGONELLA to the genus. Still, Linnaeus ; s name being the oldest, must be retained under the more restricted sense, and thus Trigonella becomes a synonym. Conchifera. J42 Meretrix tenuis, M. & H. (Cytherea), 1860, Proc.

From their paradoxical nature, they have been considered Ce- phalapoda, Zoophytes, Brachiopoda, and as a totally distinct order. Mr. Woodward, in a very able paper in the tenth volume of the Quarterly Jour- nal of the Geological Society of London, points out their true character, refers them to the Conchifera, and considers them a family, related to the CJiamaceti and Cardiadae. I am inclined to consider them rather as a suborder of the Con- chifera. The reasons given by Woodward for separating them from the Brachiopoda^ and uniting them with the Conchifera, are as follows : "1. The shell is composed of three layers, which is not the case in any Bra- chiopod. "2. The prismatic-cellular structure is like that of Perna and Aetherio, and not like any Brachiopod.

" 5. Each valve is unsymmetrical. "6. The valves are right and left, not dorsal and ventral. "7. They are articulated by teeth and sockets, which is not the case with Crania; and the teeth are developed from the free valve. In all fixed Brachio- pods, the teeth are on the fixed valve. "8. The Hippiiritidae had a large internal ligament (like Spondyhis) for open ing the valves. "9. The muscular impressions are two only. "10. The so-called vascular impressions are on the rim of the shell, not on the disc, as in Crania. &c. "11. The Hippuritidae have a distinct pallial line/' The above reasons*are certainly conclusive, as far as regards their separation from the Brachiopoda, but I cannot understand how they fix any reasonably close family relations with either of the families to which Mr. Woodward refers them.
