Description

The length of the shell varies between 3.4 mm and 5 mm.

The solid shell is opaque, yellowish or fulvous brown. It is sometimes bifasciate, with rather broad longitudinal riblets, vanishing below, crossed by spiral undulating lirae, forming intersectional nodules. The shell contains 7-8 whorls, somewhat flattened in the middle, the last dilated. The suture is channeled. The outer lip is varicose.[https://www.biodiversitylibrary.org/page/11027383#page/370/mode/1up G.W. Tryon (1884), Manual of conchology, structural and systematic : with illustrations of the species; Academy of Natural Sciences ser. 1, vol. 9] {{source-attribution}}

Distribution

This species occurs in the Arctic Ocean off Greenland, in the Atlantic Ocean from Norway to the Azores. It is also circumlittoral in the Mediterranean Sea (Spain, Corsica, Greece, Turkey).

Fossils have been in Pliocene strata in Cotentin, France.
