The anal fasciole is depressed, forming a constricted concave band near the posterior edge of the whorl which is thickened and marginate.

On the anterior side of the fasciole the shoulder of the whorl forms the periphery on which arc (thirteen on the body whorl) short, rounded, wavelike nodules or axial ribs which are slightly protective and do not extend over the base.

On the fasciole and base these are more or less obscured by spiral impressed lines with much wider interspaces, which appear feeble and as if obsolete where not eroded.

The outer lip is simple with the sulcus near the suture, rather wide and deep when complete.

The body has a white callus and near the insertion of the columella a single very strong sharp edged spiral plication extending into the spire.
