Spire rather low; aperture broadly elliptical,pointed above and obtusely so at the base; eolumellar cavity ofmedium size, with a single strong spiral ridge near the anterior margin.Surface of the shell marked by from 8 to 11 strong spiral ridges, leavinga plain space at the base of the shell equal in width to that of two of theridges; surface marked also by somewhat more distant, transverse,broadly rounded ridges, which are noclose at the points of junction withthe revolving ridges." (Weller)Remarks.-"The type of the species is a large example, and llas then~al.kings more strongly impressed upon the surface of the cast than isnsnally the case."
