- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 63 , Three species of the Apogon bandanensis group are found in the Red Sea, the widespread Apogon guamensis, the endemic Apogon annularis, and a new endemic species Apogon zebrinus. Colour patterns, number of gill-rakers, body depth, second anal spine length, pectoral-fin length, and caudal peduncle depth are important aids for identification of the Red Sea species. Two synonyms of Apogon guamensis were based on juvenile material: Apogon ocellatus from Madagascar and Apogon spongicolus from the Red Sea. Rüppell’s, Günther’s and Klausewitz’s concepts of Apogon annularis are reviewed. Apogon erdmani is a synonym of Apogon annularis. Apogon savayensis and another wide spread new species were not found in any Red Sea collections we examined.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 48 , Two new amphiliid catfish species from west Africa are described. A new Paramphilius from the Little Scarcies River basin in Guinea, is the third species of the genus from that area. It has a relatively deeper body and longer fins than other upper Guinean Paramphilius species. The new species of Doumea from the Cross River in Nigeria and Cameroons is characterised by a long predorsal length and a relatively short stout caudal peduncle.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 15 , A study of the eels which have been referred to Muraenesox McClelland clarifies taxonomic confusion in this group and shows it to contain three genera and seven species. M cinereus (Forsskål, 1775) occurs from the Red Sea across the Indian Ocean northwards to Japan . M. bagio (Hamilton, 1822) has a wider distribution from South Africa throughout the Indo-west Pacific north to Japan and south to Sydney. Congresox Gill is revived for C. talabon (Cuvier, 1829) and C. talabonoides (Bleeker, 1853) both of which occur in the central Indo-west Pacific. Cynoponticus Costa is represented by C. savanna (Bancroft, 1831) in the West Atlantic, C. ferox Costa, 1845 in the East Atlantic and Mediterranean and C. coniceps (Jordan and Gilbert, 1881) in the central East Pacific.

Smith Institute of Ichthyology; No. 13 , A new species of small Barbus is described from the Olifants River System, western Cape Province, South Africa. The new species is restricted to a single tributary complex of the river system and appears closely related to B. calidus. Diagnostic features include pharyngeal teeth formulae, colour pattern, and dorsal and anal fin ray characteristics.

A new species of the klipfish genus Springeratus (Clinidae) from the Indian Ocean

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 9 , Klipfishes of the subfamily Clininae are among the dominant intertidal fishes in southern Africa. Except for a few tropical clinine members such as Clinus xanthosoma Bleeker, Clinus ekloniae McKay and Petraites roseus (Gunther), these diverse temperate forms seem to be replaced by members of the Blenniidae in the intertidal zone of the tropical Indo-Pacific. Klipfishes have not been collected often in the tropical IndoPacific, but often enough to indicate a distribution for C. xanthosoma from Japan through the Philippines to Indonesia and Ceylon. In a recent publication Shen (1971 b) has brought our knowledge of C. xanthosoma up to date and described a new genus, Springeratus to house this species. The status of C. halei has been and still remains uncertain since Day described it in 1888. While collecting fishes at Mauritius, an undescribed intertidal clinid was obtained. This population of live-bearing klipfish contributes to our understanding of the zoogeography and possible relationships of Australian and southern African Clininae. Penrith (1969: r 14) hypothesized sea-weed transport of a clinid ancestor from Australia to South Africa. The Mauritian species favours her hypothesis as well as casting some doubt on the validity of Springeratus as a genus different from Clinus (sensu Penrith, 1969).

- Description: Online version of original print edition of the Special Publication of the Rhodes University, Department of Ichthyology, No. 4 , A commercial haul off the Limpopo River mouth in 260 - 270 fathoms collected 35 eels of the genus Bathymyrus Alcock, 1889, described here as B. smithi sp. nov. This has a shorter head and pectoral and a more posterior dorsal origin relative to the pectoral fin than in B.echinorhynchus Alcock, 1889 from the Bay of Bengal and B.simus Smith, 1965 from the South China Sea. B.smithi is also distinct in having extra-oral rostral teeth present but less conspicuously developed, more numerous vertebrae (150 — 155, compared with about 125 — 130 in the other species) and drab coloration. An osteological study shows that, although it has certain unique features, B.smithi is very closely similar to congrids of the subfamily Anagoinae. There are valid reasons for using the term Bathymyrinae for this group of congrid eels.

- Description: Online version of original print edition of the Special Publication of the Rhodes University, Department of Ichthyology, No.1 , Ascomana gen. nov., based on A. eximia sp. nov. is described from a single 700mm leptocephalus collected off Cape Town. It displays the following characters which in combination distinguish it from known eel genera: — Jaws moderately produced, hyomandibula essentialy vertical, short postocular region, occipital crest present, slender upwardly-curved lower jaw, pectoral fin with very numerous rays (23-24); larva reaching at least 700mm, eye not telescopic, caudal not attenuated or rounded, very numerous teeth, intestine a straight tube, pigment mainly as a series of large melanophores along the ventral body wall from throat to vent. The new genus and species shows some resemblances to the nessorhamphid eels. An elongate (565mm) leptocephalus, also collected from off Cape Town (that is, in the locality of the Dana "giant" eel-larvae), is identified with Leptocephalus giganteus Castle and is the second undoubted specimen of this species.
