LEPIDOSIEENID^l. 



the head (in half- grown and adult specimens), three to five times in the interocular width. 

 Dorsal fin originating at equal distance from the occiput and from the anal opening, 

 or nearer the latter. Fore limb longer than the posterior and provided with a well- 

 developed fringe; no fringe on the hind limb. Tail, when intact, more or less 

 prolonged into a filament. 55 to 70 scales in a longitudinal series from the gill- 

 opening to above the vent, 40 to 50 round the body. 



Grey or olive-brown to blackish above, yellowish white or pinkish beneath, more or 

 less spotted or speckled with black ; the lines of sensory canals brown or black. 



With the exception of one from Ugalla and another from the shore of Lake 

 Tanganyika, the specimens of this species examined by me, whether young or adult, 

 show no traces of external gills. The anal opening is as often on the right side as on 

 the left; out of twenty-five specimens brought home from Entebbe by Mr. Degen, 

 eleven have it on the right, fourteen on the left. The bones and teeth are always 

 white. The ribs, in the five specimens examined, number 35 to 40 pairs.

 inhabiting West Africa, from the Senegal to the Niger, and Lake Chad, which differs
