Features: 5-7cm long. Shell typical helmet shape with a large body whorl and tiny spire, thus resembling a bonnet. The shell has spiral ribs, 25-40 on the body whorl. Outer lip reflected, toothed on the inner edge. White, cream, pink or blue-grey. Sometimes unmarked, sometimes with 4 or 5 spiral bands of brown spots. It has a white body and the sole of the foot appears to be black. The operculum is fan-shaped and pale yellow. |
