The altitude of the shell attains 2.5 mm (0.10 in), its diameter 5.1 mm (0.20 in).

The small shell is convex-depressed. The epidermis is white and immaculate. The suture is distinctly impressed. The shell contains more than four whorls. These are convex with very fine, oblique, parallel striae, which become obsolete on the base. The aperture is sub-circular, slightly modified by the penultimate whorl. The lip is thin and acute. The umbilicus is large and deep, not exhibiting all the whorls. ^[2]
