The British Museum is indebted to Mr. F. H. Mallard for a 

 small series of tishes obtained by him in the Solwezi River, 

 a tributary of the Ohifulowa River, flowing into the Zambesi 

 near the dividing range between the Zambesi and the Congo. 

 It contains representatives of six species, two of which are 

 here described as new. The known species are Barhus 

 eufcenia, Blgr., JB. lineomaculatus, Blgr. (tirst described from 

 British East Africa, but since obtained at Insiza, Rliodesia, 

 by G. French and in the Belgian Congo at and near Elisa- 

 bethville by Dr. L. Stappers), Synodontis macrostigma, Blgr. 

 (discovered iu the N^gami basin), and Uaplochromi's rno^ad, 

 Casteln. 



Barhus hariltoides. 



Depth of body equal to length of head, 3,^ times in total 

 .length. Snout rounded, shorter than eye, which is 3 times
