XXIII. — Description of a neiv Characinoid Genus of I^ish from 

 West Africa, By Dr. Albert Gunther. 



[Plate v.] 



A SMALL collection of reptiles and fishes from tbe western coast 

 of Africa, just procured for the British Museum, contains a 

 single example of a Characinoid form which is of great interest, 

 inasmuch as it is allied to Ichthyhorus'^ y a genus from the Nile, 

 which, till very recently, was scarcely known. It differs so ma- 

 terially from the East-African form, that it must be referred to 

 a separate genus, which I name 



Phago. 

 In general appearance strikingly similar to Bpinachia. Dorsal 



* Kner does not appear to liave been aware that these fish were known 

 already to Joannis, and that I had founded a genus for them, when he 

 published his genus Psalidostoma, which is evidently identical with 

 Ichthyborus. Psalidostoma caudhnaculatum, Kner, is probably synonymous 

 with Ichthyborus microlepis, Gthr.
