Description

The shell grows to a length of 32 mm. The shell is light yellowish brown or yellowish white. It shows prominent, distant ribs, forming a strongly tuberculate shoulder, and revolving striae. The anal sinus is produced upwards. The inner lip is thickened below, forming with the axis a false umbilicus.[3]

Distribution

This species occurs in the demersal zone of the Atlantic Ocean off Sierra Leone and from Gabon to Angola.

gollark: Settings are in a gazillion random places, and the prompts for, say, in one memorable instance the log-in-through-QR-code thing are "fun" instead of useful and practical, too.
gollark: Such are the problems of centralized platforms.
gollark: Discord's got a worrying privacy policy, tends to break randomly, has random UI changes, has the ridiculous "no custom clients" thing, is primarily free and thus probably monetizing in problematic ways, is closed-source and not self-hostable, and has kind of bad UI.
gollark: It's basically just direct client/client communication instead of client-server-client.
