- 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.

- 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.

- 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.
