Description

The length of the shell varies between 10 mm and 20 mm.

This unpretending little species is easily recognized by its black colour and faint sculpture. A row of small tubercles ascends the spire, scarcely discernible on the last whorl, which (as in Crassispira rudis) descends and rises again at the aperture, making the spire-outlines curvilinear. The first three whorls are smooth. The surface shows extremely fine lines of growth, faintly decussated by spiral striae. The outer lip is sharp, not serrated, with a swelling behind. The anterior sinus is very distinct, as in Strombus. The posterior notch is deep. The sutural callosity is large, joining the well-developed inner lip. The operculum is shaped as in Drillia maculosa, with more or less of a reddish tinge. The spire is generally incrusted with blackish mud, sometimes bearing round flat egg-cases, pierced in the middle.^[2]

Distribution

This species occurs in the Pacific Ocean off Panama; fossils were found in Pleistocene strata of the Gulf of California.
