1 am very doubtful as to what these birds really are. 

 The above species has only been found in Uganda, except 

 for two instances in the Rift Valley {Jackson), also females. 

 My birds are very yellow underneath, streaked with black, 

 and with small, much-curved bills. They agree exactly with 

 females of this species from Uganda. 



The only other possibilities appear to be : 



Cinnyi-is mariquensis suahelicus Reichw., in which the bill 

 is much too large ; and 



Cinnyris mariquensis osiris Reichw., of which there are 

 four specimens in the Museum from East Africa, and 

 which appear to differ from typical C. m. osiris in that the 

 red pectoral band of the males is very much darker. 



In both these, however, the female is too light in colour, 

 and in the latter the tail is too short, 41 mm. against 45 of 

 my birds. I did not see a male in either case. C. m. micro- 

 rhynchus is a still smaller bird.
