The length of the shell attains 3 mm.
(Original description) The very glossy shell has rounded whorls, rather taper in shape, and finely reticulated. The colour of the shell is transparent yellowish-white. The aperture is sub-orbicular and has a thin lip. The ridges on the body whorl do not extend over the outer lip. The shell has a small umbilical chink. The length of the shell is the tenth of an inch. Its breadth one third its length.
Distribution
This species occurs in the Eastern Atlantic, from Norway to the Strait of Gibraltar; intertidal to ca. 100 m depth; rare and rather local in the Western Mediterranean (Corsica, Greece) in 50-200 m. Gorringe Ridge and Ampère Seamount, rare in 265-320 m. It is absent from Baltic Sea and the eastern basin of the English Channel.
Fossils have been found in Pleistocene strata on Sicily, Italy.
