The semi-transparent shell has a white color beneath a yellow epidermis.

The inner lip is thickened, extremely short, and slightly disunited from the body.

It is very concave on the columella, where it is bent back so as to cover the umbilical perforation, which presents a narrowed and not pervious but very strong depression.

It has a central nucleus and many spiral whorls, which seem to become more numerous toward the margin.

[4] This marine species occurs off Victoria, Australia, the Kerguelen Islands and the Southern Indian Ocean.
