‘“‘Subulate, volutions fourteen, bicarinate, carina distant with a con- 
cave interval, the lower carina near the suture; surface covered with nearly 
equal fine closely-arranged strize, with a minute intermediate line; aperture 
longer than wide.” 
The above is Mr. Conrad’s description of this species. The shell is 
extremely variable in the rate of increase in size in different individuals, 
and also somewhat so in the general expression of the volutions, owing to 
the comparative distance between the two principal carina, and their dis- 
tance from the suture. But they all agree by having the carine much 
nearer the lower part of the exposed surface of the volution than to the 
upper, which gives a long slope from the upper one to the suture line above; 
usually greater than the distance between the two carine; while the space 
below the lower carina is not more than half as wide as that between the 
carine. In the fine lines covering the surface they are very uniform, 
although the small intermediate line does not always appear. The lower 
edge of the volution is either obtusely carmate or rounded, and the lower 
surface covered with fine lines, as is the surface. In older shells the carinze 
are less distinctly marked. The aperture is subquadrate and the apex, as 
seen in very perfect specimens, would appear to have been open and filled 
from within. 
Localities: All the specimens yet seen have been from Shiloh, N. J. 
Mr. Conrad’s types were from the same place. Collections at Rutgers Col- 
lege, N. J., and National Museum, Washington, D.C. Mr. Meek gives it 
as from North Carolina.
