DISTRIBUTION. — Western Indian Ocean, Maldive Islands, southern Japan, south China Sea to eastern Australia, Melanesia, Kermadec Islands, Micronesia, Polynesia to Pitcairn Island ( Waller 1972: 234; Dijkstra & Marshall 1997: 101; 2008: 51). Depth range 0-60 m (Dijkstra unpubl. data). Austral Islands ( Richard 1986, and present records), alive at 2-52 m depth.

REMARKS

The present specimens are indistinguishable from the type material from the Marquesas Islands. The subspecies P. coruscans hawaiensis ( Dall, Bartsch & Rehder, 1938) occurs around the Hawaiian Islands ( Waller 1972: 232).

This species was formerly placed in Chlamys or Semipallium , but actually assigned to Pascahinnites , based on the lack of an external prismatic layer in the early right dissoconch stage ( Paulay 2003).
