GREENWOOD Marcusenius victoriae (Worthington) (Text-fig. 2G) This species closely resembles M. cyprinoides (and like that species was formerly included in the genus Gnathonemus). The musculature too is virtually identical with that of M. cyprinoides, although the anterior intermandihularis (text-fig. 14) is a little further reduced in size, and the muscle connecting the fourth and fifth ceratobranchials is present.

Gnathonemus longibarbis (Hilgendorf) (Text-fig. 2H) The snout is moderately short (especially as compared with other Gnathonemus species; see Taveme [1968]), the mouth small and terminal, and there is a long tubular submental barbel. The posterior intermandihularis is an extensive muscle, originating, as is usual, over the hyohyoideus and from the interopercula. It has strong connective tissue attachments (in which some muscle fibres occur) to the ventral margin of the MC. Fig. 14. Marcusenius victoriae: ventral hyoid musculature.
