The shell is false-umbilicate and has a regularly conic shape, being concave on the underside.

The base of the shell is concave and concentrically lirate, with about 6 to 8 lirae that are granose in the young and nearly smooth in the adult.

The columella is oblique, with a strong fold above, projecting into the aperture with a very deep insertion.

The umbilical tract is white or yellowish, spirally costate in young and smooth in fully adult specimens.

This is a very distinct form, with an aperture so oblique that it resembles a Calyptraea Lamarck, 1799 [2] This species occurs in the Indian Ocean off Madagascar and the Mascarene Basin.
