The specimen before me is in many respects like C. heug- 

 lini subrufescens, but in some respects it recalls donaldsoni. 

 Thus, the upper surface is dark slaty grey without the slightest 

 trace of olive-brown (approaching the latter form). Further, 

 the central tail-feathers are black and the outer-web of the 

 outer tail feathers blackish, much the same as in subrufescens, 

 but in contradistinction to the latter the next three consecutive 

 tail-feathers are also furnished with black edges on the outer- 

 web, the fifth is entirely black with rusty-brown streaks along 

 the shaft. I have compared my specimen with the subrufescens 

 specimens in the Berlin Museum but have not found any which 

 resemble mine in the uniform grey tint of the back. It is 

 possible that mine is only an aberrant bird of subrufescens, 

 which, according to Reichenow (op. cit.) were shot in the 

 Nairobi district, and therefore I have not given it a new name.

1 (5 ad. 1. 7. Mount Elgon. 



Only once did I meet with this rare bird on Elgon. It 

 frequented the dense thicket of the undergrowth at an altitude 

 of over 10000 feet. 



V. Someren (Nov. Zool., vol. XXV, 1918, p. 290) says of 

 this form that it differs from other closely related forms „by 

 the absence of an yellow on the tail-feather". But this is not 

 correct, for the original description says that „the outer tail- 

 feathers are black except at the extreme base, which is yellow", 

 and my specimen agrees with that description. On the other 

 hand I agree that the white spot above and in front of the eye 

 extends almost from the nostril to the posterior angle of the eye.
