The specimens were obtained at Kondo-Kondo and in 

 Corisco Island. The original description of C. Iceviceps runs 

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

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

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

 and is quite insufficient for exact determination of specimens. 

 The typical specimen came probably from Liberia.

I believe that the specimens so named should be reunited 

 with Schilbe mystus.

This is a species clearly distinct from Ch. macrops, having 

 the adipose fin much shorter and further distant from the 

 dorsal fin. In this respect it agrees with Ch. nigrodigitatus , 

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

 mouth. However, I have examined large specimens which 

 it is difficult to refer to either of these two species with cer- 

 tainty. And the difficulty is increased, as I find that there 

 are specimens with eleven and with thirteen anal rays in 

 both the narrow-snouted form {Ch. nigrodigitatus) and the
