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).
