A new species of small-sized scorpionfish, Scorpaena bulacephala, is described on the basis of seven specimens collected from off Norfolk and Lord Howe Islands, northern Tasman Sea, southwestern Pacific Ocean, at depths of 86–113 m. The new species is closely related to a Hawaiian endemic species, S. colorata. The two species are distinguished from other Indo–Pacific species of Scorpaena by the following combination of characters: exposed cycloid scales covering the anteroventral surface of the body and pectoral-fin base, the lateral surface of the lacrimal without spines, and 17 pectoral-fin rays. The new species differs from S. colorata in having 39–44 longitudinal scales rows and relatively short fin spines and rays, especially short longest pectoral-fin ray (31.5–33.5% of standard length). Morphological changes with growth and sexual dimorphism of the new species are also discussed.

A new species of goby, Eviota rubriceps, most similar to E. nigrispina, is described from Indonesia, Papua New Guinea, and the Philippine Islands. Both species have the lower two thirds of the body dark in preserved specimens, belong to the cephalic sensory-pore pattern group 2 of Lachner and Karnella (1980), have an 8/7 dorsal/anal formula, and unbranched pectoral-fin rays. Eviota rubriceps differs from E. nigrispina in live and preserved coloration and in caudal-peduncle depth. The descriptions of E. mikiae and E. raja are expanded based on additional materials.

Navigobius kaguya is described on the basis of two specimens from the Ryukyu Islands, Japan, and Luzon, Philippines. It differs from other described species of the genus in live coloration, and in having: second dorsal-fin rays I,16; anal-fin rays I,16; pectoral-fin rays 21–22; gill rakers 5–6 + 17; and first dorsal fin weakly to moderately incised between spines, taller than second dorsal. It closely resembles an undescribed species from Bali and the Maldives, but differs in lacking an orange-red mid-lateral stripe. The possible placement of Navigobius khanhoa in Oxymetapon is discussed.

Two new species of Trichomycterus from isolated small river basins of southeastern Brazil are described: T. pantherinus, new species, from the Rio Santa Maria da Vit ria basin, and T. caudofasciatus, new species, from the Rio Itabapoana basin. Both new species are diagnosed by a combination of morphological features, also occurring in T. alternatus and T. longibarbatus, including number of pectoral-fin rays, odontodes and branchiostegal rays, long filamentous first pectoral-fin ray and wide opercular patch of odontodes. Trichomycterus pantherinus differs from other congeners by possessing a light orangish yellow flank with dark brown to black rounded spots. Trichomycterus caudofasciatus is distinguished from other species of the genus by having four gray bars on the caudal fin.

Ages of adult sockeye and chum salmon were estimated from examination of the second anterior pectoral fin ray, and were compared with estimates from their scales or otoliths. For sockeye, only the ocean age could be estimated. Freshwater annual rings could not be distinguished on their fin rays even though they were present on their scales or otoliths. In general, the three methods provided the same estimates of ocean age. Agreement of estimates of ocean age by one to five readers ranged from 78.9 to 98.8%. For chum salmon, the scale and fin ray methods generally provided the same estimates of total age. Agreement of estimates of total age by one or two readers ranged from 73.8 to 99.3%.

Eggs of 10 pairs of wild ninespine sticklebacks from Hobson's Brook near Cambridge, England, were reared under various controlled temperatures. Temperature for optimum survival to hatching differed between genotypes. Ninety young were examined for counts of vertebrae, spines, and dorsal, anal, and pectoral fin rays. Survivors at high temperature had markedly more vertebrae than survivors at low. Curves of temperature against vertebral count may be V-shaped for each genotype, and optimum survival temperature may produce lowest vertebral count. More basal supports to the dorsal and anal fins and spines were produced at high temperature. Disruptions in one-to-one serial conformity between ray or spine, basal, and vertebral series became progressively commoner at higher rearing temperatures. Parents showed positive correlation between dorsal and anal fin ray counts and number of caudal scutes. Comparisons are made with Gasterosteus aculeatus.

A New Species

A new species of Gephyrocharax is described from the río Cascajales basin, a tributary of the río La Colorada, río Magdalena system, Colombia. The new species is distinguished from its congeners, exceptG. melanocheir, by the absence of an adipose fin in most specimens and by the possession of a lateral branched pectoral-fin ray in males with a distal fan-shaped structure with minute bony hooks and a dark blotch or a few scattered dark brown chromatophores along its branches. The new species differs from G.melanocheir by the absence of an intense black pigmentation at the base of the anterior five dorsal-fin rays, the number of vertebrae (40-41vs. 38-39), the frontals contacting each other anterior to the epiphyseal bar in adults (vs. the absence of contact), the posterior margin of the mesethmoid straight in its central portion (vs. strongly concave at this point), the pouch scale of mature males reaching caudal-fin ray 11 or the area between caudal-fin rays 11 and 12 (vs. reaching only to caudal-fin ray 10 or the area between caudal-fin rays 9 and 10), the number of minute terminal branches of the lateral branched pectoral-fin ray of mature males (60-88 vs. 28-54), a longer black lateral stripe along the body in males (reaching to the base of the caudal-fin rays vs. reaching the middle of the length of the caudal peduncle), and the snout length (28.3-31.8% HLvs. 22.2-28.0% HL). The diagnosis ofGephyrocharax is modified to include species with the adipose fin variably present

The species of the genus Trichomycterus inhabiting the laguna dos Patos system are reviewed and five species are recognized. Trichomycterus tropeiro Ferrer & Malabarba has a restricted range and is endemic to the uppermost portion of the rio das Antas. Trichomycterus balios, n. sp., is distributed in the upper portion of the rio das Antas and rio Caí basins. Trichomycterus diatropoporos, n. sp., is endemic to the rio da Prata basin, a tributary of the rio das Antas. Trichomycterus poikilos, n. sp., is widely distributed in the upper portion of the rio Jacuí basin and tributaries of the rio Taquari-Antas. Trichomycterus brachykechenos, n. sp., is endemic to the upper portion of the rio dos Sinos. The new species are distinguishable from most congeners, except for T. davisi, T. mboycy, T. naipi, T. payaya, T. papilliferus, T. perkos, T. plumbeus, and T. tropeiro by the lower number of pectoral-fin rays (I+5-6) and by the first pectoral-fin ray not prolonged as a filament. Other characters distinguish the new taxa from these eight species. The distribution of the genus in the laguna dos Patos system is discussed and a taxonomic key is provided.
