A new genus and species of cat-fish (Pisces, Clariidae) from the deeper waters of Lake Victoria, May 1958
1958
Greenwood, P. H.
Recently three specimens of an undescribed clariid fish were caught in the deeper waters of Lake Victoria. In all superficial characters the species could be referred to the genus Olarias (sub-genus Olarias) and to the species group Olarias werneri Blgr., C. alluaudi Blgr., C. eupogonNorman. However, closer study showed that the suprabranchialrespiratory organism were virtually absent and the suprabranchial chamber almost non-existent. Since the fishes were adult and of a size at which related Clarias species possess well-developed suprabranchial organs, itmust be concluded that this is the definitive condition for the species.
