- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 38 , Recent collecting in the Malawi lakes Chilwa and Chiuta has revealed a new haplochromine cichlid fish, Astatotilapia tweddlei, which is described and illustrated. It is distinguished from most members of this genus by an elongate, rounded caudal fin. Although having a distinctly different colour pattern and more slender pharyngeal bone, it shows a greater similarity to A. paludinosa, known only from the Malagarasi Swamp 1200 km to the north in the Zaire ichthyofaunal province, than it does to members of this genus from the closely adjacent Zambezi province from which this wetland system, in the East Coast province is separated by only some 50 km.

Paragaleus leucolomatus, a new shark from South Africa, with notes on the systematics of hemigaleid sharks (Carcharhiniformes: Hemigaleidae)

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 37 , Paragaleus leucolomatus sp.n. is described from a pregnant female shark 957 mm total length collected off Kosi Bay, Natal, South Africa. This represents the first Paragaleus and the second hemigaleid species recorded from South African waters. P. leucolomatus differs from its congeners by its broad snout, long mouth, lower anterior teeth mostly erect-cusped and without distal cusplets, 180 total vertebrae, and coloration. The species has conspicuous white-edged fins, a black apical spot on its second dorsal, and dusky blotches on the underside of its snout. P. leucolomatus may be conspecific with a Madagascar Paragaleus erroneously assigned to the West African P. pectoralis. Diagnoses of the Family Hemigaleidae and the Genus Paragaleus are presented, as well as diagnostic keys to hemigaleids of the western Indian Ocean and to Paragaleus species.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 36 , Fusigobius duospilusis described as a new species from several localities in the tropical Pacific and Indian oceans. This species differs from other species of Fusigobius in pectoral ray and gill-raker counts, coloration, reduced pelvic frenum, branching of the pelvic rays, presence of two large black spots on the first dorsal fin and shape of the first dorsal fin. The species is free living on sand. Males average a larger size than females. Sex ratios are uneven, with about twice as many females as males. Fusigobius longispinus Goren is recorded from several localities in the western Indian Ocean, where populations differ morphologically from Red Sea populations. Fusiogobius neophytus africanusls regarded as a synonym of F. neophytus.
