The periphery of the body whorl is inflated. The base of the shell is very strongly suddenly rounded, widely and deeply umbilicated. The entire surface is marked by numerous fine, closely spaced, spiral striations. The aperture is broadly ovate. The posterior angle is obtuse. The outer lip is thin.
