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.

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.

 =* The generic name, given by Parkinson in "Organic Remains," vol. iii, p. 
 184, must take precedence of the name Aptychus ordinarily used. The type is T. 
 lata, and is well figured, although the author did not know where to place it in 
 the classification. There has been considerable doubt in regard to the nature of 
 ' ' Aptychus." D'Orbigny considered it a pedunculated cirrhipede ; but it is now 
 generally believed to be the operculum of Ammonites.

 * Although the typical forms of these "species" (?) are very distinct from 
 each other and can generally be recognized at a glance, I have never heen able 
 to detect any difference in the septa of Morton's types ; and the number and ar- 
 rangement of the ribs and tubercles vary so, that I cannot agree with my friends, 
 Messrs. Meek and Hayden, in considering them distinct. They might well be 
 designated for convenience, S. Conradi var. Abyssinus, Mandanensis, Nicolletii, Ac. 
 
 t Although I agree with Mr. Conrad in believing this to be a good genus, still, I 
 fear that his diagnosis of the genus may be incorrect in one particular. He says 
 that the large portion is " suddenly recurved." It may be the case, but the evi-

 dence is very slight. 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.

 coming from a white limestone, since ascertained to belong to the Eocene forma- 
 tion. They are all from South Carolina. The same deposit extends as far south

 * By some unaccountable mistake, when describing this species, I confounded 
 two specimens, both of which, in the top view, resemble Morton's figure of D. 
 lapidosa, even to the manner of their fracture. 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. W. M. (J.

 * 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.

 it. 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-

 * "Neocomien," d'Orbigny, "Jurassic," B. & C. Mr. Conrad proposed a new 
 genus to receive this curious and beautiful species, which he called Lit/iotroc/tns. 
 It was accidentally omitted at the proper place in this enumeration. After care- 
 fully studying a very fine specimen in my own collection from near Copiapo, 
 Chili, I am unable to detect any valid characters by means of which it can be 
 separated from Turritella, although its wide whorls and low spire induced Von 
 Buch to consider it a Pleurotomaria.

 * The generic name Bucardia, being pre-Linnaean, must give way to Poli's 
 name, that being the first one given to the genus under the binomial system. 
 
 t I place this name as a synonym of V. Conradi, only from the evidence of 
 the figure given in the Synopsis. 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.

 * It is utterly impossible to identify with any degree of certainty the species 
 described in the "Prodrome." The only description given of this species is 
 "Espece voisine du C. Marrotiana, mais plus large a Textremite anale ; ayant 
 une tout autre forme que le C. vadosa, Mort." This description is even more 
 full than the average, but can be applied with equal propriety to four other 
 known species.

 fibrosa has never been reported above the upper greensand in England or France. 
 Should it prove identical, as Messrs. Meek and Hayden think, it will be one of 
 the rare instances of a species peculiar to a certain deposit in one locality, being 
 found in another deposit in a distant locality.

 # In retaining the generic division, Exogyra, I do not know that I can give 
 a better explanation than that given by Leymerie, in the fourth volume of the 
 Memoirs of the Geological Society of France. 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. D'un

 autre c6te, si ces derniers offrent parfois et accidentellement un crochet tourne 
 exterieurement, c'est la une disposition purement accidentelle et facile d'ailleurs 
 si distinguer, par sa variabilite et son irregularite, de celle si reguliere, et si fon- 
 damentale qui caracterize les Exogyres." 
 
 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.

 * Prof. Marcou appears vexed that American Palaeontologists refuse to follow 
 him, in his obviously incorrect determination of the species, in the work quoted 
 above. 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. Tucumcarii, see Proc. Acad. Nat. Sci. for December, 
 1860. It is incorrectly referred to the Jurassic by Prof. Marcou.

 * I have never (except in the "Ripley group," which has a mineral character 
 very much like the Speeton clay of England) seen but one or two fragments 
 of Inocerami from New Jersey, where there are whole beds composed of shells. 
 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.

 * This species, together with I. problematicus and several other of the lower 
 chalk species, appear to be common to Europe, and the United States west of the 
 Mississippi j and I am inclined to think that the divisions Nos. 1 and 2, and a part 
 or perhaps the whole of No. 3 of Meek and Hay den's section in Nebraska, and 
 some of the lower beds of Texas, may be found to be of the same age as the lower 
 chalk of England, the Turonien of d'Orbigny. 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.

 =* The cretaceous species referred by d'Orbigny and others to the genus Janira, 
 are certainly generically different from the type Pecten maximus. 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.

 therefore bears date 1767. 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.

 f I have, in my collection, five lower valves of a small species of oyster so near 
 this species, that I can find no difference of sufficient value to found even a va- 
 riety. I have never seen the upper valve, but, should it agree with M. Leyme- 
 rie's figures as well as the lower ones, it will remove all doubt of their specific 
 identity. My specimens are from near Mullica Hill, New Jersey.

 * I place this species in this genus, because Mr. Conrad has informed me that 
 it has the hinge of a true PAPYRIDEA, and not that of PHOLADOMYA, as believed 
 by d'Orbigny. Specimens found in the "Ripley Group, ' : a deposit resembling 
 somewhat the Speeton Clay of England in its lithological characters, have enabled 
 him to ascertain without doubt the true generic relations of these beautiful shells.

 may, however, be some mistake in the locality.

 * After a careful comparison of Roeiner's figure and description with authentic 
 specimens and figures of Lamarck's species, I am convinced that they are different. 
 Besides the outline, the most obvious difference is in the number and arrangement 
 of the ribs. I take pleasure, therefore, in naming the species after my friend, 
 the able State geologist of Texas.

 * After a careful study of all the material at my disposal, and after reading the 
 views of the numerous able students who have studied the subject, I have been 
 led to believe that this curious group of genera, constituting according to some 
 authors a distinct order, according to others, a suborder, and considered by still 
 a third class, as only a family, are more nearly related to the Conchifera than to 
 the Brachiopoda. 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.

 "3. No Brachiopod has a subnacreous shell with water chambers. 
 
 " 4. The upper valve has a different structure from the lower. 
 
 " 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.

 * See "Synopsis of American Cretaceous Brachiopoda," in the Proceedings of 
 the Academy of Natural Sciences, January, 1861. I have since ascertained that 
 the form from New Jersey, although labelled lacliryma by Dr. Morton, is specifi- 
 cally distinct from his types from South Carolina, which are Eocene, and that the 
 New Jersey species is as yet undescribed. The fact that the New Jersey speci- 
 mens were labelled by Dr. Morton, misled me.
