Shell turreted, ventricose ; whorls (7) somewhat convex and striated; striz but faintly 
impressed, and about 15 in number upon each whorl; the base deeply striated; aperture 
depressed, nearly circular ; columella excavated. 
The figure is subpyramidal, the length of the whorls being rather more than half their 
transverse diameter ; the sutures of the whorls are deeply marked, the base of the last 
whorl is deeply grooved ; the base of the aperture is very wide, and the transverse diameter 
of the aperture is nearly equal to the longitudinal. The length of the entire shell is about 
3 inches, the transverse diameter through the last whorl is 21 lines. 
Locality. Great Oolite near Scarborough. In the middle and west of England this 
species occurs in the upper beds of the Inferior Oolite and Coral Rag.
