dc.description.abstract Naso caesius, a new unicornfish (Perciformes: Acanthuridae: Nasinae) is described from specimens from the Marshall Island s, Mariana Island s, Hawaiian Islands, and Pitcairn Group. Its occurrence in the Society Island s, New Caledonia, Fiji, and the Coral Sea is confirmed by underwater photographs. It is very similar to and has been confused with Naso hexacanthus, differing in having sma11er bladelike caudal spines that do not become sharply pointed and antrorse as on large male N. hexacanthus, a pale instead of black tongue, entirely pale lower-limb gill rakers (base of rakers blackish in N. hexacanthus), and in life color. It is bluish gray overa11 (not yellowish ventra11y as on N. hexacanthus) and lacks the black borders on the opercle and preopercle and the white lower lip usua11y seen on N. hexacanthus ;one common color phase, which can be rapidly assumed, has vertically elongate spots on the body that vary from paler to darker than the ground color. Naso thorpei Smith, known from one 314-mm specimen from Durban, South Africa, is questionably distinct from N. hexacanthus. Naso tapeinosoma (Bleeker) and N. vomer (Klunzinger) are probable junior synonyms of N. hexacanthus. en_US
