Description (Original description in Latin) The acute shell is chrysalis-shaped and narrowly perforate. It displays a chestnut-brown color. The aperture appears almost disjoint from the spire and features a more or less double peristome, where the inner lamella is incised posteriorly. The operculum is horny, multispiral, circular, and flattened. Gould, A. A. (1862). Descriptions of new genera and species of shells. Proceedings of the Boston Society of Natural History. 8: 280-284
