The resulting interstices are often deep and hollow, particularly noticeable on the last three whorls.
The body whorl is slightly produced at the base. Dorsally, near the periphery, it is encircled by an obscure, calcareous band that is interrupted. The aperture is narrow. The outer lip is thickened and denticulate internally. The sinus is conspicuous and broad. The inner lip is marked with two small teeth toward the base.
