92 PALEONTOLOGY OF NEW JERSEY. 
middle of its length, the upper one of which is much the smaller; volu- 
tions marked by distant vertical folds only faintly seen on the cast, and 
only on the upper portions when visible; on the inner surface of the cast, 
between the volutions, the vertical plications are strongly marked, as in all 
the species of the genus yet observed; but I have not seen any remains of 
spiral lines as on most of them, still, I presume they have existed. 
The species is very closely related to two other species of the genus 
found in the New Jersey Cretaceous, V. Gabbi Whitt. and V. Abbotti Gabb, 
the former from the Lower Green Marls, and the latter from the Middle 
beds. From V. Gabbi it differs in the form of the volutions, having the largest 
diameter proportionally higher and less rapidly contracted below, and in 
wanting the angularity of the shoulder near the upper surface. It may 
possibly be only a variety of this form, but I have held the specimen in 
hand for months, hoping to obtain some connecting forms, but none have 
been observed, and I can not feel satisfied to include it among the forms 
of that species as now known. 
Formation and locality: In ferruginous layers of the Lower Green 
Marls, at Mullica Hill, New Jersey, where it is associated with V. Gabbi

Plate x1, Fig. 8. 
Shell slender, extremely elongated, turreted; spire very much ele- 
vated and slender; whorls numerous, slightly convex on the surface and 
very distinctly banded on their lower margin; body volution proportion- 
ally more convex than the others, being swollen near the middle of its 
length; attenuate and rostrate below, and nearly or quite one-half the 
length of the shell as seen from the outside of the aperture; sutures very 
distinct, bordered by a broad band which is very distinctly separated from 
the other part of the volution by an impressed line nearly or quite as 
deep and distinctly marked as the suture line itself; surface of the shell
