Description

The size of the shell varies between 15 mm and 36 mm. Rather low-conic shell is conspicuously radiately plicate above. The folds are somewhat sigmoid and oblique, bearing a series of short rounded knobs above, and terminating in short spines, eighteen to twenty in number, at the carinated periphery. The base of the shell is flat, squamosely lirate. The aperture is tinged with green, especially at the columella. The wrinkled operculum is deep green.[3]

Distribution

This marine species occurs off Hawaii, French Polynesia and the Marianas.

gollark: I see.
gollark: Honestly, I feel like the technical characteristics of how your package manager manages packages is more important than the GUI you stick on it.
gollark: Hopefully we'll eventually get a good CC package manager. One day...
gollark: I wonder if I could get pockets big enough for my reasonably thick 14" laptop.
gollark: Personally, I would find life without a hardware-keyboard device very annoying.
