Shell, as shown by the cast, elongate, fusiform, and slender, with mod- 
erately full-volutions and distinct suture lines; spire short, the body volu- 
tion 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. 
This species is the most slender form of the genus, except V. mucronata 
Gabb, and may be readily distinguished from that one by the greater 
length of the spire and proportionally shorter aperture of that species. I 
have not been able to identify any other specimen of this species than the 
type specimen. It is certainly a species distinct from any other described, 
and must be a comparatively rare form. 
Formation and locality: The specimen is composed of a hard black 
marl resembling that from the Lower Marl Beds in many places in Mon- 
mouth County, New Jersey, and is said under the original description to 
have come from the Delaware and Chesapeake Canal. On the label accom- 
panying the specimen, written by Mr. Gabb, is marked “Cret. N. J.”
