Material examined

Xisha Is. 3 specs, 58M-1542, Shu Is. (Xisha Is.).

Distribution

Taiwan, Xisha Is.; Japan, Philippines, Fiji.

Remarks

Reeve (1843) described this species with delicate sculpture, and the spiral ribs coloured alternated with irregular white and black. The number of axial ribs on the last whorl are variable, up to 16, with the average number 12 to 14 ribs. Our three specimens were collected from intertidal zone in 1958, purely white, and the axial ribs on the last whorl numbering 13 to 15. Zhang (1995) reported that his specimens collected from Taiwan, were white, with brown on point. The difference in shell colour may be the result of depigmentation by the tidal action and sunshine.
