Description

A typical shell has a height of 10 mm and a diameter of 15 mm. The imperforate shell has a low-conoidal shape above, but is convex beneath. It is glossy and smooth except for fine growth lines and almost obsolete spirals. Its color is white, copiously marbled with purple-brown and pinkish above, with some opaque white spots, and a few indistinct articulated spiral lines. The base is white, with a pink central area. The 5½ whorls are convex. The body whorl is wide and narrowly rounded at the periphery. The ovate aperture is oblique. The lip is thin and simple, callused near the columellar insertion. The umbilicus is wholly filled by a red callous pad, roughened by several irregular vein-like grooves.[2]

Distribution

This marine species occurs off Japan.

gollark: It has ADTs and other such usefulnesses.
gollark: It's quite cool, though; it's a functionalish systems programming language.
gollark: Also, try Rust; less undefined behaviour problems.
gollark: I don't use twieter.
gollark: Fast enough? Are you actually likely to have significant performance issues?
