Shell is large, solid and heavy with a strongly sculptured surface which is frequently covered with a horny epidermis.

The body whorl is provided with a strongly noduled, angular shoulder near the suture. a few nodules also occur lower down on the whorl. The surface is coarsely sculptured with close-set spiral ridges which occur in distinct groups of four or five on the body whorl. The broadly expanded, wing-like outer lip of the aperture extends upwards at the upper end over the surface of the spire almost up to the apex, and is prolonged at its outer edge into seven, elongated, finger-like, deeply channelled processes. The columella and the interior of the aperture are smooth and polished.
