Synonym(s): roseus Quoy & Gaimard, 1834.

Typical shell-length 80 mm. Lives subtidally and offshore on sand and mud, especially in sheltered environments. Non-native. Occurs in eastern Australia (QLD, NSW, TAS and VIC); also New Zealand. In Tasmanian waters, this species is now widespread and often abundant, following unintentional introduction from New Zealand.
