The whorls are encircled by numerous fine unequal lirulae or striae.

The base of the shell is convex, generally a little more coarsely lirate than the upper surface.

The aperture is subquadrangular, oblique, and not angled at the junction of basal lip and columella.

The large, white umbilicus is funnel-shaped and margined by one or several spiral riblets.
