==Description==
The height of the shell attains 1.4 mm. The small, high shell has a conical shape. It is scalar, with a sharp, expressed carina at the periphery and a second carina above, angulating the 5½ whorls.
Sculpture : there are a few close-set slight spirals on the edge of the flat base. Tthere are many not close-set, flexuous, longitudinal ribs
above the periphery, but on the base merely lines of growth. These ribs in crossing the upper carina form small sharp-pointed tubercles, of which there is also a trace on the lower carina. The superior sinus lies just above the upper carina, the basal sinus toward the middle of the base. Both are well marked. The apex is small and flat, the smooth embryonic 1¼ whorl hardly rising at all. The whorls show a slow increase. The columella is perpendicular, with a strong rounded sinus, which corresponds to a swelling within the umbilicus. The umbilicus is not large, but deep, funnel-shaped, with a puckered sharp edge.〔(Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia )〕
