- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 65 , Apogon niger Doderlein, 1883 of the western Pacific and Apogon nigripinnis Cuvier, 1828 (Apogon thurstoni Day, Amia nigripes Ogilby, and Amia atripes Ogilby are synonyms) of the eastern Indian Ocean and Australia are regarded as valid species distinct from Apogon pharaonis Bellotti, 1874 of the western Indian Ocean (Apogon suezii Sauvage, Amia ocellata Von Bonde, and Apogon duops Barnard are synonyms). Apogon nigripinnis differs from A. niger in having a large ocellus between the lateral line and the pectoral fin. A lectotype for A. niger is designated. A. pharaonis differs from both these species in having shorter pelvic fins, 16-21 instead of 15-18 gill-rakers, and 3 dark bars on the body. Apogon sialis (Jordan & Thompson, 1914), type locality Japan, is the senior synonym of Amia cathetogramma Tanaka, 1917, also described from Japan. Apogon pseudotaeniatus Gon, 1986 from the Red Sea, previously misidentifiedas A.bifasciatus Rüppell, is very similar in colour pattern to A. sialis; it differs in having a larger caudal spot, a dark instead of pale intestine, and in several morphometric characters.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 62 , A new species of cardinalfish, Apogon photogaster is described based on 11 specimens from Madang Lagoon in Papua New Guinea and Galoc Island in the Philippines. This new species has 15 pectoral rays, 2 predorsal scales, 15-18 gill-rakers (8-9 developed), and 7 gill-rakers on the ceratobranchial o f the first gill-arch. It has a unique bioluminescent system, including a light organ branching forward from the second loop of the intestine and a diffuser organ along the ventrolateral part of the body.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 43 , In his revision of the genus Bathylagus, Norman (1930) recognized five species from the Southern Ocean. The taxonomic status of these species is re-evaluated by using morphometric data and the number of vertebrae, anal fin rays, gill-rakers, lateral scale series and pyloric caeca. Principle component analysis was carried out in support of species separation, using selected body proportions. Three species, namely B. antarcticus, B. gracilis and B. tenuis, are recognized here. B. gracilis and B. euryops latifrons, both described by Lonnberg, 1905, were found to be synonymous. A key to the species of Bathylagus in the Southern Ocean is provided.
