VIII. Description of a Nciv Fish of the Genus Paratilapia, from 

 the Upper Zambesi. By G. A. BOULENGEK, F.E.S. 



(Plate XIV.) 



ON a recent visit to the Victoria Falls, Mr. W. L. Sclater obtained 

 three fishes in the Zambesi, immediately above the falls, which he 

 has kindly sent to me for examination. One, known as the Tiger 

 Fish, is a Characinid, Hydrocyon lincatits, Blkr., widely distributed in 

 Africa (from the rivers of Guinea to the Congo in the West, from the 

 Blue and White Niles to the Limpopo in the East) ; the two others, 

 generally known as Bream, and prized as excellent table fish, 

 belong to distinct species of the Cichlid genus Paratilapia, Blkr. 

 One of these, originally described by Gunther as Hemichromis 

 robustus, from Lake Nyassa, had previously been recorded by me 

 from the Upper Zambesi under the name of Hemichromis jallce, the 

 description being based on a young specimen, which was afterwards 

 identified by me with Giinther's species as Paratilapia robusta. 

 The other, which is allied to the Nyassan species Paratilapia afra, 

 Gthr., and P. modesta, Gthr., represents a new species which I have 

 much pleasure in naming after Mrs. Sclater.
