Description
The width of the shell is 0.9-1.1 mm. The height of the shell is 1.6-2.2 mm. It is wider than the shell of Carychium tridentatum which it closely resembles. As in C. tridentatum shell is dull white and cylindrical and the mouth is oval with two denticles and a thickened lip. However if the last whorl above the aperture is opened this shows the plica parietalis (a spiral ridge on the parietal region projecting into the interior of the shell) descending in a simple way downwards.[2]
