Description

The length of the shell attains 5.7 mm, its diameter 2.1 mm.

(Original description) The narrow shell has a fusiform shape. It contains 6 whorls, including the protoconch of 2 smooth convex whorls, with simple suture. The whorls of the spire are convex, with simple suture. The body whorl is tapering anteriorly. The aperture is narrowly oval, scarcely contracted behind, widely open in front, no siphonal canal, only channelled. The outer lip is thin, simple, uniformly convex in profile. There is no distinct sinus posteriorly. The inner lip is slightly thickened on the straight columella, with two faint plaits or nodules. The colour of the shell is white, with a spiral row of some seven brown spots, showing just above the suture, and winding to the middle of the outer lip.[2]

Distribution

This marine species is endemic to Australia and occurs off South Australia.

gollark: Um.
gollark: Seems wasteful.
gollark: With null-terminated strings, getting the length takes `O(n)` time, and it is possible to mess up very easily.
gollark: Yes, that is the superior one.
gollark: They are the LEAST cool string type.
