Description
The height of the yellowish-white shell reaches 1½ mm. The umbilicate shell has a turbinate-subdepressed shape. It is longitudinally and subobliquely striatulate. The short spire is obtuse; The spire consists of 3-3½ whorls. The first whorl is smooth, and separated by simple sutures. The remaining whorls are rather plane, lamellosely bicarinate above the middle, channelled between the carinae. The body whorl is subdescending, and is a little constricted just below the carina, then inflated and convex. The groove terminates a short distance behind the lip in an oblong foramen, which does not attain the edge of the lip, a smooth space intervening. The aperture is ovate-rounded. The simple peristome is thin, acute, and subcontinuous.
