The solid, conical shell is umbilicate or imperforate. The
spire is elevated or depressed. The oblique
aperture is subrhomboidal. The outer
lip is smooth within. The arcuate
columella is above continued in a callus over or halfway around the
umbilicus, which when open shows one or more spiral ribs inside. The base of the columella shows two or more denticles.[3]
