Description
edit
(Original description) The stout shell is medium-sized. The protoconch is conical, consisting of two and a half whorls, about the last one sculptured with axial riblets. (One species referred to this genus has a stout, cylindrical, smooth nucleus of two whorls.)
The aperture is long and moderately narrow. The anterior canal is short, barely emarginate.
The outer lip is varicose. The anal notch immediately adjoining the suture, is moderately deep, and broadly rounded. The interior of the outer lip bears a low broad denticle on the notch. The parietal callus is thin. The sculpture consists of axial ribs, which may be varicose here and there on the body whorl, and spiral threads, with microscopic frosted spirals in the interspaces. [2]
