Description

The shell grows to a length of mm and a diameter of 1.1 mm. The umbilicate, white shell has a depressed globose shape. The shell contains 3-3½ whorls. The upper whorl is almost plane, the middle one is round and angulated and contains spiral, microscopic striae. The cancellation of the body whorl is strongly developed, so that the pittings between the cross-ridges are deep and striking. The suture is deep and channelled. The uppermost of the six revolving lirae borders the channelled suture, and the umbilicus is encompassed by a swollen ridge, which is in addition to the six line referred to. The microscopic striae are seen upon the lirae.[1]

Distribution

This species occurs in the Atlantic Ocean off St Helena

gollark: Plausibly, if we remove all the air from the computers.

gollark: I would use minoteaur for notes, but it's very WIP.
gollark: Oh yes, I too like the bad fonts of any handwritten thing ever, no search, and no font size etc. controls?!
