The pear-shaped aperture measures half the total length and has a weak sinus at the shoulder of the outer lip. The incrassate outer lip has a smooth interior. The stout columella is slightly bent.Gould, 1860, Descriptions of new Shells collected by the United States North Pacific Exploring Expedition; Proceedings of the Boston Society of Natural History, vol. 7 (1859–1861), p. 338
