Popis
— (1) The length varies from 0.65 to 1.0 mm.
— (2) The shells are transparent with a light brownish hue. They are decorated with darker brown colour bands. The colour bands end at some distance before the aperture. There is a whitish spot at the apex.
— (3) Ornamental sculpture is completely absent.
— (4) The shells are not very solid, there is no labial rib, nor does the aperture show any other peculiarities.
— (5) Large specimens have about 3.5 whorls.
— (6) The umbilical chink is well developed.
— (7) The dimensions of the apex vary: d = 0.9-0.11 mm, D = 0.14-0.17 mm.
— (8) Seen from aside, the nucleus is very little prominent, and circumscribed by a shallow suture. Seen from aside, the nucleus and first 1/4 whorl form a medium high segment of a sphere, circumscribed by a rather shallow suture.
— (9) At a magnification of 40 x , no ornamental sculpture can be seen on the protoconch.
