Description

This is the largest shell in the genus Phansianelle, with its height varying between 40 mm and 100 mm. The rather thin shell is elongatedand 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.[1]

Distribution

This marine species occurs off Australia and Tasmania.
