Description

The size of the shell varies between 9 mm and 14 mm. The shell has a straightly conical shape. It is imperforate, solid, and rather thick with a yellowish flesh-color. It is sculptured spirally with numerous smooth riblets, alternately larger and smaller, 8 or 9 on the penultimate whorl, about 14 on the base, some of the interstitial ones near the axis quite small, the outer ones subequal in size. The spire is conic, its outlines straight. The sutures are scarcely visible except for a slightly wider cingulus above them. The whorls number about 6. They are flat, the last angular, nearly flat beneath, shortly deflexed at the aperture. The oblique aperture is rhomboidal, with a couple of prominent riblets inside the upper lip. The basal lip is thickened. The columella is straight or a trifle projecting in the middle.[3]

Distribution

This marine species occurs off Southern Australia and Tasmania.

gollark: Such forms of communism seem impräctical.
gollark: Added to my questioning profile.
gollark: What about the cost? You didn't answer "even xy cryoapiocognitopyroform".
