Phasianella australis

Phasianella australis, common names the Australian pheasant, painted lady, and pheasant snail, is a medium-sized to large species of sea snail with a calcareous operculum and a colorfully patterned shell, a marine gastropod mollusc in the family Phasianellidae.

Description
This is the largest shell in the genus Phasianella, with its height varying between 40 mm and 100 mm. The rather thin shell is elongated and has a pointed-ovate shape. The conical spire is elevated. The shell contains 7-8 somewhat convex whorls. These are slightly flattened below the sutures. The long-ovate aperture is somewhat pyriform and forms usually less than half the total length of shell. The outer lip is thin. The columella shows more or less a white shining callus. The surface of the shell is variously longitudinally clouded and transversely articulated with red and purple olive on a polished flesh-colored, cream or white ground. The color pattern is extremely variable.

Distribution
This marine species occurs off Australia and Tasmania.
