Description.: — "Shell, as shown by the cast, elongate, fusiform 

 and slender, with moderately full volutions and distinct suture 

 lines; spire short, the body volution as viewed from the front 

 forming from three-fourths to four-fifths of the entire length, 

 and the narrow, anteriorly prolonged aperture more than one- 

 half of the length; volutions four or more in number, the last 

 one most ventricose above the middle of its length and narrowed 

 and prolonged below; columella showing two strong oblique 

 folds at about the middle of the aperture; surface unknown." 

 (Whitfield.) 



Remarks. — ^In the original description of this species it was 

 said toi come from the "Delaware and Chesapeake Canal," but 

 the type specimen in the collection of the Philadelphia Academy 

 of Science is labeled in Gabb's handwriting "Cret. N. J." In the 

 recent collections of the Survey nO' specimens have been met with 

 which can be referred to this species. If the type specimen came 

 from New Jersey, the lithologic character would indicate that 

 it was from the Navesink marl. 



Formation and locality. — -Navesink marl, ? Monmouth County. 



Geographic distribution. — New Jersey.
