 D. 1/14-15. A. 12. P. 1/7. V. 6. 



Body moderately elongate, of nearly the same depth in its 

 whole length, the tail being strongly compressed. Head depressed 

 much broader than deep, two-sevenths of the total length (without 

 caudal); the very small eye entirely in the anterior half of the 

 head ; snout broad, depressed, two fifths of the length of the liead, 

 nearly twice as long as the interorbital space is long. Mouth 

 anterior, with the upper jaw rather larger, surrounded by fleshy 

 lins • all the barbels are rather thick near their base : the 

 maxillary extending to the middle of the operculum, the outer 

 mandibulary to the base of the pectoral fin ; the inner mandibulary 

 rather shorter than the maxillary. The maxillary patch ot teeth 

 is single, oblong, small, but wider than long; the mandibulary 

 patches separated in the middle, smaller than, but similar m 



outline to, the maxillary. . i -.i .+^^^„ 



Pectoral fins short, not longer than ventral, with a strong 

 spine, which, however, is enveloped in thick skm, only its point 

 bein- free. Dorsal fin very low, only about half as high as the 

 body^ with a singularly short spine, not quite half as long as the 

 snout. Adipose fin long, low, commencing shortly behind the 

 dorsal and subcontinuous with the caudal. Caudal rounded. 



Reddish-brown, darker on the back, body, dorsal and caudal 

 fins, with scattered round black spots, the spots on the caudal fin 

 being the more numerous and smaller. 



Total length 122 millim. „ -v 



Two specimens from the River Ibbi (Apollonia). 



Syngdontis robbianus J. A. Smith. 



Several young specimens (3-6 in. long) from the R. Offim._ 

 On comparing these specimens with the single young specimen 

 of S. robbianus,! find that they have the interorbital space a 

 little broader than the Old Calabar fish. This does not seem to 

 me to constitute a distinctive specific character. 



Malapterurus electricus L. 



A young specimen from the R. Oflfim. 



Barbus camptacanthus Bleek. 



Many specimens were collected at Infoan, at the town of 

 Akropon, and on the River Atesu. 



Barbus trispilus Bleek. 



Many specimens from Infoan, Akropon, and Ingogosu, a viUage 

 in the mining centre of Kinkiankwa.
