[edit] Shell description
The shell is minute, white, subglobose, with a low spire and rounded whorls, strongly sculptured with rather widely spaced, sharp, oblique axials, extending from the suture to the narrow, deep umbilicus, which is margined by a sharp keel. Spiral threads between the axials are distinct only on approaching the umbilicus. The foramen is large, oval, distant from the outer lip, and at the end of a short excavated selenizone.
The shell height is up to 0.94 mm, and width 1.14 mm.
