Casts, which are unquestionably of this species, are not uncommon 
among the Kocene fossils from New Jersey. The specimens present in the 
internal casts and impressions of the exterior all the features recognized on 
or presented by the Claiborne examples, and have the same size and relative 
proportions of those shells; so that there can be no reasonable question 
of their specific identity. The spire is elevated and presents an apical 
angle of from 25° to 30°, and consists of about eight volutions. This will 
not include some two or three of the extreme upper whorls of the apex of 
the shell which would not be preserved in the cast. The whorls are flat- 
tened in the direction of the spire, and although the sutures are distinctly 
marked, they are not deep or conspicuous. The anterior beak is not shown 
to its full extent in any of the impressions, nor is the margin of the lip fully 
represented; but enough of both remains to show their similarity to the 
Claiborne specimens. The spire has been coated to near if not quite to the 
apex in one of the examples examined; while the posterior canal has ex- 
tended at least to the top of the fourth volution, if it has not extended to 
the fifth; and has left a broad cicatrix marking the width of the callus bor- 
dering the channel. On one or two of the fragments of the casts of the 
spire the longitudinal or vertical folds of the upper volutions which charac-
