hell description

The shell is rather small, white, semi-transparent, sub-discoidal, with a low convex protoconch of one smooth whorl. The post-nuclear sculpture has prominent, rather distant, narrow spiral cords, three or four on the spire-whorls, following a rather wide sub-sutural sulcus, and nine or ten on the body whorl and base; wider-spaced on the base, and devoid of spirals over the latter half of the base. The umbilicus is wide and perspective. The aperture is circular, and the peristome is discontinuous.

The shell height is up to 1.5 mm, and the width is 2.5 mm.
