 2 (5(5 ad. 3. 6., 8. 6. Mount Elgon 6.500 ft. 



Occurred sparingly on the eastern slopes of Mount Elgon. 

 Frequents the scrub and acacia-clad regions where it most fre- 

 quently associates with the Serin Finches, but is much shyer. 



Both specimens are in full plumage and one has the feat- 

 hers of the back uniform reddish brown, the other very dark 

 reddish brown with lighter edges. Reichenow states (op. 

 cit.) that the outermost tail-feathers are white on the outer 

 web. In these two Elgon specimens the outer-web is one-third 

 white in the central, one-third black in the other two-thirds but 

 the distal two-thirds of the innerweb is white. 



Wing, 81 85 mm. tarsus 18 mm. 



Irides dark-brown; upper mandible dark-drey, lower man- 

 dible brownish red with black tip; legs yellowish brown (some- 

 times with a grey tint).

At no place through which our expedition passed has this 

 race been common. I did not observe the bird on the eastern 

 slopes of Elgon, but the most northern place I met with it 

 was Soy. 



Reichenow (op. cit.) writes that the two outer rectrices 

 are white with black inner-web. In all my specimens the outer 

 rectrices are entirely white, the second black on the inner part 

 of the inner-web. 



The young bird from Londiani is, as Reichenow points 

 out, greyish brown on the upper part, but the one from Kismu 

 is dark-grey (also the head).

The females appear in general to be somewhat smaller 

 than the males, but otherwise there is no difiference between 

 the sexes.
