- Description: Online version of original print edition of the Special Publication of the Rhodes University, Department of Ichthyology, No. 2 , Specimens from the southeast African coast conform well in essential characters with those displayed in radiographs of Muraena tota cinerea Forsskål from the Red Sea. In contrast, Japanese specimens which have been assigned to M.cinereus have more precaudal vertebrae, a higher total number of vertebrae, more numerous dorsal rays, a broader interorbital and a larger eye. They should therefore be set aside as distinct from Forsskål’s species. An available name for these is possibly M.singaporensis (Bleeker, 1853) although insufficient is known about M.cinereus - type eels in the Indo-Malayan region for this name to be confidently applied to the Japanese form. In many features western Indian Ocean M.cinereus closely resembles M.yamaguchiensis Katayama & Takai, 1954, also from Japan.

- 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.
