Gerald R. Allen: Description of a New Wrasse (Pisces: Labridae: Cirrhilabrus) from Northern Sumatra, Indonesia, pp. 45-50
Cirrhhilabrus joanallenae, new species is described from 3 specimens, 41.2-46.2 mm SL, collected at Weh Island, northern Sumatra. It is closely allied to C. rubriventralis from the W. Indian Ocean Red Sea, both species exhibiting an elevated “pennant” at the beginning of the dorsal fin, large club-shaped pelvic fins, and a single row of scales on the cheek. However, the new species differs in life colours of male and females, in having fewer scales on the cheek, less conspicuous serrations on the preopercular margin, and 15-16 rather than 14 pectoral rays.
John E. Randall and Joachim Frische: Hybrid Surgeonfishes of the Acanthurus achilles Complex, pp. 51-56
Three hybrids are known among the four species of surgeonfishes that comprise the Acanthurus achilles complex: A. achilles x A. nigricans (documented by Randall, 1956a); A. leucosternon x A. nigricans (previously known from an aquarium photograph, 1982, here reported from a specimen from Indonesia); and A. japonicus x A. nigricans (based on an underwater photograph from Lanyu, Taiwan).
Richard Winterbottom: Four new species of Trimma (Gobiidae), from the Indian and Western Pacific Oceans, pp. 57-66
Four new species of the genus Trimma are described: Trimma anaima is a small species found in both Indian and western Pacific oceans. Trimma anaima has no scales in the predorsal midline, no interorbital or postorbital trenches, unbranched fifth pelvic fin-ray, and four small dark saddles over the dorsal midline. Trimma bisella, to date found only at Mauritius, has no scales in the predorsal midline, an interorbital trench, unbranched fifth pelvic fin ray, and two white saddles on the caudal peduncle. Trimma halonevum has predorsal scales, a moderate and steep-sided interorbital trench, and a fifth pelvic fin ray with a single dichotomous branch. It is salmon-coloured with red-brown and yellow spots on the head and body. Trimma halonevum has a wide distribution in the western Pacific ad has been found in the Indian Ocean at Christmas Island and the Maldives. Trimma omanensis has a crescent-shaped bar on the posterior edge of the pectoral base, head and predorsal midline naked, well-developed interorbital and postorbital trenches, a fifth pelvic fin ray which branches twice, and has to date only been found in the Gulf of Oman.
J. B. Heiser, R. L. Moura, and D. R. Roberson: Two new species of Creole Wrasse (Labridae: Clepticus) from opposite sides of the Atlantic, pp. 67-76
Two new species of labrid are described, one each from the eastern and western sides of the equatorial Atlantic. Clepticus africanus, n. sp., is described from fourteen specimens collected from São Tomé Island in the Gulf of Guinea off the equatorial African coast. Clepticus brasiliensis, n. sp., is described from nine-teen specimens (plus additional material) collected from the coast and offshore islands of Brazil south of the Amazon. Neither species is significantly different in morphometric or meristic characters from the heretofore sole member of the genus, the tropical western North Atlantic Clepticus parrae. Both new specis are distinguished from C. parrae. Both new species are distinguished from C. parrae by coloration and by the development in adults of greatly extended fin rays (two-thirds the standard length) from the tips of the upper and lower lobes of the forked caudal fin: the mostly balck African creole Wrasse with one filament on each lobe of the caudal, and the mostly mauve to purple Brazilian Creole Wrasse with two or more such filaments. The two new specis represent a pair of amphi-Atlatic sister taxa.
Gavin D. Alexander and Colin E. Adams: The phenotypic diversity of Arctic charr, Salvelinus alpinus, (Salmonidae) in Scotland and Ireland, pp. 77-88
The high phenotypic variability of Arctic charr and the nature of polymorphism in the species are briefly summarized. Photographs of Arctic charr from populations in Scotland and Republic of Irelad are presented to illustrate some of the phenotypic diversity of the species in these two countries.
