The specimens were obtained at Kondo-Kondo and in 

 Corisco Island. The original description of G. Iteviceps runs 

 as follows :— " Height at anus a tenth of length ; head 

 (laterally) a sixth, its breadth an eighth ; the surface smooth ; 

 maxilhary barbels twice as long as head. D. 86, A. 61, —

 The tj])ical specimen came probably from Liberia.

 which, as a rule, has a more contracted snout and narrower
