372 ZOOLOGICAL EESULTS OF THE EUWENZOEI EXPEDLTloX. 



c. 2 imm. Fort Beni, Semliki Valley. 3000 ft., 20th July. [No. 2418. G. L.] 



Iris dark hazel ; bill and feet black. 



This form differs only from C. verticalis Hartl. in having the mantle slightly darker. 



Specimen a is marked " breeding." Specimen c is a young female in a very 

 interesting stage of plumage : the feathers of the crown appear spotted, being rufous 

 margined with black, and amongst them a few white feathers of the adult plumage 

 are making their appearance. Specimen b is in nearly mature plumage, but the wing- 

 coverts are margined with greyish-brown and spotted at the extremity with pale rufous. 



[A few examples of the Black-backed Kobin-Chat were met with in the lower valleys 

 on the east side of Ruwenzori, but they were never seen above an elevation of 5000 ft. 

 and were rather rare birds. A single specimen was shot in the dry acacia-country at 

 the south end.— B. B. W.)

 observed in the Semliki Valley. It has a short sweet song, generally uttered from the 

 top of an acacia-bush. — B. B. W.~\
