Gerald R. Allen, Mark V. Erdmann and Abraham B. Sianipar: Descriptions of two new species of moray eels (Pisces: Muraenidae) from northwestern Flores, Indonesia, pp. 37-46
Two new species belonging to the muraenid genus Gymnothorax are described from northwestern Flores, Indonesia. Gymnothorax longinaris is described from a single specimen, 236.5 mm TL. It differs from all other members of the genus in having a combination of enlarged posterior nasal appendages, 117 total vertebrae, and a colour pattern consisting of 14 dark-brown bars and 14 large, ocelli markings (when viewed dorsally) on the dorsal fin. Gymnothorax paucivertebralis is described from two specimens, 183.0-227.0 mm TL. Although it exhibits a colour pattern that is similar to G. kidako from the Indo-Pacific region, it differs from that species and all other western Pacific congenerics in having an exceptionally low number of total vertebrae (101-103). The colour in life is pale yellow with a brown reticulated network and prominent brown banding on the dorsal and anal fins.

William D. Anderson, Jr., G. David Johnson and Ai Nonaka: Review of the Groppos, Grammatonotus (Percoidei: Callanthiidae), pp. 47-80
The family Callanthiidae contains two genera, Grammatonotus (with ten nominal and a few putative species) and Callanthias (the Splendid Perches, with seven species). We provide characters that distinguish callanthiids from other percoids and that distinguish Grammatonotus from Callanthias. Also provided are descriptions of Grammatonotus and its species, a key to the species of Grammatonotus, and comments on other aspects of the biology of Grammatonotus.

Gerald R. Allen, Mark V. Erdmann and William M. Brooks: Pentapodus berryae, a new species of Whiptail (Pisces: Nemipteridae) from Papua New Guinea, pp. 81-88
Pentapodus berryae is described from 4 specimens, 121.2-133.4 mm SL, collected from Milne Bay Province, Papua New Guinea. Diagnostic features include an emarginate caudal fin without filamentous lobes, scaled suborbital, no enlarged caniniform teeth in the lower jaw, second anal spine shorter but slightly more robust than third anal spine, eye diameter greater than snout length, 2.9–3.1 in head length, lower limb of preopercle with three rows of scales, lateral-line scales 45-49, pectoral-fin rays 17, pelvic fins relatively short, not reaching level of anus, and mainly blue colour with broad yellow stripe on head and anterior two-thirds of body. It is most similar to the sympatric P. aureofasciatus and P. trivittatus, but differs in lacking enlarged canines in the lower jaw and in having a larger eye. The habitat consists of steep outer reef slopes below about 60 m depth.
