Arturo Acero P. and Richardo Betancur-R: Arius cookei, a new species of ariid catfish from the tropical American Pacific, pp. 133-138
A new species of sea catfish (family Ariidae) from the tropical eastern Pacific, Arius cookie n. sp., is described. It can be easily separated from other western American ariid species by its elongated supraoccipital process, which is 1.5 to 1.7 times longer than the width of its base (in specimens over 343 mm SL). The species is known from fresh and brackish waters from Costa Rica to Colombia.
Gerald R. Allen and John E. Randall: A review of the leucogaster species complex of the Indo-pacific pomacentrid genus Amblyglyphidodon, with descriptions of two new species, pp. 139-152
The Indo-Pacific pomacentrid Amblyglyphidon leucogaster was previously thought to consist of several distinct geographic colour variations. However, the present study indicated there is a complex of four species: A. leucogaster (Bleeker) from the western Pacific and eastern edge of the Indian Ocean, A. orbicularis (Hombron & Jacqinot) from Samoa, Fiji, and New Caledonia, and two new species described herein – A. indicus from the Red Sea and Indian Ocean, and A. melanopterus from Tonga. The members of the leucogaster complex are mainly differentiated by a combination of colour pattern and gill-raker counts. A key to the species of Amblyglyhidon is included.

John E. Randall: Two new damselfishes of the genus Pomacentrus from the south-west Pacific, pp. 167-176
Pomacentrus callainus, formely identified as a colour variety of the western Pacific P. lepidogenys, is described from specimens from Tonga and Fiji. It is distinct from P. lepidogenys in its overall blue-green colour with a wedge-shaped black spot at the upper base of the pectoral fin, higher gill raker counts (22-25, compared to 20-23 for P. lepidogeys), deeper body (47.5-51% SL compared to 43.5-47% SL, for P. lepidogenys), longer dorsal spines (longest spine 14.7-17.1% SL, compared to 12.7-14.7% SL in P. lepidogenys), and probable larger size. Pomacentrus spilotoceps is described as new from four specimens from Tonga and underwater photographs from Fiji. Its closest relative appears to be P. chrysurus, known from the western Pacific to the Maldive Islands. P. spilotoces differs in having in orange or yellow spots on the operculum and before and above the base of the pectoral fins and 22-24 gill rakers, compared with 18-19 for P. chrysurus).
