[The Grey-breasted Bush- Warbler was very numerous on the plains all round the 

 mountains, but was never seen on Ruwenzori above 5500 ft. It was met with 

 throughout the journey across the Congo Forest, and was seen as far down the Congo 

 as Coquilhatville. Its habits are very similar to those of the Common Wren, and its 

 note, which is continually uttered, is almost identical with that of the Common 

 Stonechat.— R. B. JV.]

a. J (? imm.). Nr. Mawambi, E. Congo Forest, 3000 ft, 24th Oct. [No. 3642. 

 R. B. W.] 



Iris dark brown ; bill black ; feet grey. 



An immature male assuming the adult plumage (?) has the upperparts strongly 

 washed with olive and the wings and tail in moult, the former being nearly complete, 

 while in the latter the feathers are all less than an inch in length. The underparts 

 resemble those of the adult male, but many of the feathers of the chin and throat are 

 in moult. 



This species was recently described by Dr. Sharpe from specimens procured by 

 Mr. G. L. Bates in Southern Cameroon. 



[A single specimen of this beautiful Orange-breasted Bush- Warbler, the only one 

 seen, was obtained in the Congo Forest near Mawambi. It was hopping about among 

 the undergrowth. — R. B. W.']
