Description

The length of the shell varies between 9 mm and 20 mm.

The characters of this shell are close to Oenopota cinerea (Møller, 1842), but the shell is longer in the spire and narrower, with slightly stronger shoulder, fewer ribs and revolving striae. The sculpture is cancellated. The aperture is broadly truncate below.[2]

Distribution

This species occurs in European waters, in the Northwest Atlantic Ocean and in the arctic waters of Canada and off Nova Zembla, Russia
