Abstract

New Zealand Oceanographic Institute collections from Raoul Island and nearby add Marginaster sp. (Asteroidea) to the fauna and contain also Helio‐cidaris tuberculata (Lamarck), Echinometra mathaei (Blainville), Echinocyamus polyporus Mortensen, Peronella hinemoae Mortensen (Echinoidea); Ophidiaster kermadecensis Benham, Patiriella oliveri Benham, Astrostole rodolphi (Perrier) (Asteroidea); and Amphiophiura kermadecensis (Benham) (Ophiuroidea). A sample from near the Star of Bengal Bank, almost midway between New Zealand and Raoul Island, contains Trigonocidaris radiata Mortensen (Echinoidea), Asteroporpa wilsoni Bell, Astroceras n.sp. and Ophiogymna n.sp. (Ophiuroidea), all new records for the Kermadec Islands area.
