Description

The size of the shell attains 15 mm. The rather thick, imperforate shell has a conic-elongate shape. The 6 to 7 whorls are planulate, the first buff, eroded, the following whitish, ornamented with sparse rosy points and angular chestnut streaks . The shell is spirally lirate, with about 8 lirae on the penultimate whorl. The subangular body whorl is depressed above. The base of the shell is convex, with about 8 concentric lirae. Tnere is no umbilical perforation. The aperture is rhomboidal. The lip is simple. The short columella is subnodose-truncate below.[3]

Distribution

This marine species is endemic to Australia and occurs off Western Australia and King Island, South Australia.

gollark: Having version control would probably make some potatOS things I've wanted possible, such as verified boot where potatOS ensures that the currently installed stuff matches a checksum, compressed updates, and updates which work if I change a non-core file (the updater logic is very weird).
gollark: And I think cloud catcher.
gollark: Monaco is the one VSCode uses.
gollark: Yes, all of those.
gollark: Probably all of those?
