Distribution. Southern Cape, from East London to Mossel Bay; shallow subtidal.

Notes. As currently interpreted this species may be composite, comprising the typical pink-spotted forticostata and a smaller uniformly white species with more finely beaded sculpture and a more constricted umbilicus in the female (McLean in lit. xi/1984). It is this small form that extends west to Mossel Bay, the typical form reaching only to Jeffreys Bay.
