Ethminolia degregorii

The very fragile, umbilicate shell has a subdiscoidal shape and is delphinuliform.

The five whorls are spirally finely striate, in the middle slightly angled or subcarinate, and flattened between the carina and the suture.

The convex base is deeply and broadly umbilicated and very finely corrugated.

The surface of the spire is ornamented with five reddish zones alternating with white punctate with rosy.

The surface of the base of the body whorl is ornamented with regularly radiating costiform white maculations.
