Lake Victoria. Ten specimens were obtained at Entebbe by Mr. E. Degen, 

 14.6-11.10.05. 



Distinguished from P. retrodens by fewer teeth, fewer scales on the cheek, frequently 

 as few as 8 soft anal rays, and rather larger scales on the body. 



* The specimen figured bears a number of black specks, due to a parasite, as noticed in the Cyprinida 3 , 

 p. 273.
