Description

edit

The height of the shell attains 5 mm (0.20 in), its greatest diameter 5.67 mm (0.22 in).[citation needed]

(Original description in Latin) The turbinated-conical shell shows minute growth striae. It is thin and scarcely conspicuously impressed. It is translucent, somewhat shiny, horn-colored and unicolored. The spire is moderately elevated, with a somewhat sharp apex. The suture is impressed. the shell contains 5 slightly flat whorls, the body whorl scarcely surpassing the spire. The whorls are obtusely subcarinate at the periphery and somewhat flat at the base. The columella is short, emitting a small, milky callus. The aperture is oblique, somewhat triangular and is horn-colored on the inside. The peristome is simple, with thin, fragile, sharp basal and outer margins. The thin operculum is horn-colored. [2]
