- 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.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 7 , A survey of ichthyological literature from 1758 until the end of 1968 reveals that information on eel larvae (leptocephali) is widely scattered and contained in at least 600 different papers. A synthesis of tlris information, essential for the correlation of larval eels with their adult species, is attempted here as a necessary adjunct to the further development of systematic studies on adults. About 450 forms of eel larvae have been described, of which nearly 100 have been at least tentatively identified; some 200 have been named as species of die genus Leptocephahis Grono- vius, 1763 (now a rejected name in Zoology), or of other larval genera; the remainder have not been named. Systematic and bibliographic information on these cel larvae is presented together with a geographic checklist and a list of myomere numbers in leptocephali. Reports of eel eggs and prelarvae are not included but these may be found in some of the papers listed. The leptocephalous larvae of other groups of fishes are excluded from this index, although references are made to relevant sources of information.

The Eel genera Congrina and Coloconger off Southern Mozambique and their larval forms

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 6 , Eight juvenile eels collected off southern Mozambique by the Galathea and identified as Congrina guttulata (Gunther, 1887) each have three well-defined, longitudinal rows of melanophores on the lateral body surface. The Dana collection of leptocephali contains many East African larvae with identical pigmentation. Their added close agreement in number of myomeres, fin-rays etc. allows such larvae to be firmly identified with Congrina Jordan & Hubbs, 1925, and specifically with C. guttulata. Leptocephalus trilineatus Castle, 1964 and L. geminus Castle, 1964, with similar pigmentation from the southwest Pacific, must therefore also belong to Congrina. Ten eels from southern Mozambique (Galathea Expedition and a commercial trawler) are identified with Coloconger scholesi Chan, 1967, otherwise known only from the South China Sea. A metamorphic lepto-cephalus of C. raniceps Alcock, 1889, from off southern India (Galathea) shows remnants of larval pigmentation, and permits the recognition for the first time of the larval characters of Coloconger.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 5 , Two hauls made in late January, 1930 off southern Africa by the Danish Dana Expedition contained developing eggs and very young larvae of the congrid eel Gnathophis capensis (Kaup, 1856). Collection of these specimens confirms the suggestion made from previous larval studies that spawning, development, and at least early larval growth of this species occurs in late summer in this area.
