Description

The species are moderate-sized. The orbicular shell is turbinately depressed. The whorls are convex, smooth or transversely striated, the last one rounded at the periphery. They have a mottled or streaked color-pattern. The umbilicus is partly closed by a callus deposit. The columellar lip ends anteriorly in an obtuse dilated callus. The callus emitted at the columellar-parietal angle of the aperture is tongue-shaped, closing the umbilicus except a rather narrow chink, or even entirely, in some species.[4]

Distribution

This genus occurs in the Central and East Indian Ocean, off East Africa, off Indo-Malaysia, and off Australia.

gollark: My main problem with cryptocurrencies is the fact that they end up needing to replicate unreasonably large amounts of data everywhere, and allocation of coins is a hard problem without any reasonably good solutions.
gollark: You obviously run into the issue of "what if the key is leaked", though.
gollark: Hypothetically you could have a cryptocurrency where only the government can issue a coin - instead of mining it (proof of work), it would just be digitally signed by a government key.
gollark: They totally can.
gollark: Having one organization perform an increasingly large amount of important functions never ends well.
