Description
The 3-6 x 5-11 mm shell has 5-6 moderately convex whorls which are rounded or very slightly keeled at the periphery. The aperture has a thin white lip inside. The umbilicus is open and usually wide at 1/8-1/4 of shell diameter. In colour the shell is brown to cream, sometimes with a light band at the periphery. The periostracum is irregularly striated, and densely covered with short (0.2-0.3 mm), curved hairs. These hairs usually remain in the umbilicus if worn away from the rest of the shell. Lost hairs leave pronounced scars.
The animal is brownish grey with a darker anterior part.
