144 PALEONTOLOGY OF NEW JEESEY. 



by Col. T. M. Bryan; several others are from Upper Freeliold. They are 

 probably from the Lower Marls, but Dr. Morton's specimen is of a rusty 

 character, unlike any other which I have seen, and appears as if it had 

 been imbedded in a ferruginous clay. A large slab of limest(5ne bearing 

 very many examples of this species as partial casts, but retaining something 

 of the surface markings, has recently been obtained from the clays at Say- 

 ersville, New Jersey, by J. H. Conger, Esq. 



TUERITELLA ? GRANULICOSTATA. 



Plate xviii, Figs. 10, 11. 



Turritella granulioostata Gabb: Proc. Acad. Nat. Sci., Phila., 1861, p. 363; Meek, 

 Check List Cret. and Jur. Foss., p. 18; Geok IST. J., Newark, 1868, p. 729. 



The following is Mr. Gabb's description of this shell: 



Shell elongated, whorls many, increasing very gradually in size, almost per- 

 fectly flat on the sides. Suture impressed, very distinct ; bordered below by a 

 slight elevation of the upper edge of succeeding whorl; lower angle of the whorl 

 rounded, subangular. Mouth small, subquadrate; anterior angles rounded. Sur- 

 face marked by about twelve fine, thread-like revolving ribs, three of which are 

 larger than the rest, are placed at equal distances from each other, and from the 

 upper and lower edges, and are slightly undulated so as to produce a series of mi- 

 nute nodes. This character shows itself to a much less extent on some of the 

 smaller ribs. Under surface of the body volution marked by a few fine revolv- 

 ing ribs, with regular concavities between them. 



This fragment, consisting of nearly four volutions, is all that is known 

 of the species. The casts referred to by Mr. William Grabb may or may 

 not belong to the same ; we certainly do not know the casts of this one 

 authentically. The surface markings are rather those of a species of Cerith- 

 ittm than of a Turritella, but the mouth is mutilated, so that its features 

 can not be satisfactorily determined. 



Fonnatioii and locality: In the Lower Green Marls, most probably in 

 Burlington County, New Jersey. The specimen is now in the collection 

 of the Acad. Nat. Sci., Phila,
