Phasianotrochus eximius

The height of the shell varies between 20 mm and 40 mm. The imperforate, solid, rather thick shell has an elongated-conical shape. It is polished and shining. The color of the shell is brown, fawn-color or rosy, with widely spaced light or dark narrow spiral lines, usually four in number on the penultimate whorl. The surface is microscopically spirally densely striate. The slender spire is straight-sided. The apex is acute. The 7 whorls are a little convex. The body whorl is rounded at the periphery. The ovate aperture slightly exceeds one-third the total length. It is brilliantly iridescent within, and sulcate. The greenish peristome is thickened. The vertical columella is toothed below the middle.[4]

This marine species is endemic to Australia and occurs in the subtidal and in the intertidal zone on seaweed off New South Wales, South Australia, Victoria, Tasmania and Western Australia.
