Description
(Original description by H. Suter) The height of the shell attains 3.2 mm, its diameter 5 mm. The small, thin and fragile, umbilicate shell has a depressed turbinate shape. It is spirally lirate. The sculpture consistis of numerous slightly elevated and rounded spiral cinguli; 6 on the penultimate, about 16 on the body whorl. Those on the upper surface show a fine spiral thread in the interstices, which are of about the same width as the riblets. The cinguli on the outer side of the base are finer and closer together. On the inner side 3 broad slightly crenulated ribs surround the
peristome is sharp, the ends approaching and nearly meeting. They are united by a white parietal callosity. The columella is vertical, arcuate, and slightly expanded. The umbilicus is about one-third of the diameter, deep and scalar.[4]
