8o4 CRETACEOUS PALEONTOLOGY. 



distant, strong and angular vertical folds, extending from the 

 suture to near the base of the beak on the body volution, and from 

 suture to suture on the others, even on the casts; surface of the 

 shell marked by very fine transverse striae parallel to the folds, 

 which are only slightly directed forward in their lower part ; and 

 by extremely faint indications of faint thread-like, raised, spiral 

 lines, divided by broad flattened interspaces." (Whitfield.) 



Remarks. — This species is closely allied to C. mullicaensis, but 

 according to Whitfild it is larger, with a more elevated and more 

 slender spire, with the body volution proportionally larger, and 

 the suture much more distinct. The species is apparently less 

 common than C. wuidlicaensis, as it has not been met with in the 

 recent collections. The internal casts of this species closely 

 resemble those of Odontofusits medians^ but they can be dis- 

 tinguished from that species by the absence oi the columellar fold. 



Pormation and locality. — Navesink marl, Crosswicks Creek 

 (Whitfield). 



Geographic distribution. — New Jersey.

Description. — "Shell moderately large and robust for its 

 length, with a short, obtusely pointed spire and very large body 

 whorl, which constitutes nearly the entire bulk of the shell ; the 

 spire, measuring from the swell oi the body volution when look- 

 ing upon the front of the shell, forming about two-fifths of the 

 entire height ; volutions four and a half to five in number, short, 

 indistinctly marked and the sutures obscure ; the body whorl some- 

 what produced below, forming a short canal; aperture large, 

 elliptical, pointed above and notched below; and about equaling 

 one-half the length of the shell ; surface of the shell marked with 

 strong, longitudinal ribs, which are quite distant and number 

 only about 10 on the body whorl; the, ribs are strong, sharply
