356 ZOOLOGICAL EESULTS OF THE RUWENZORI EXPEDITION. 



throat, as well as the middle of the breast and belly, of a pale soiled yellowish colour. 

 The pectoral band, which is interrupted by a yellow patch in the middle, as well as the 

 sides and flanks, dark tawny brown. Wing 2*25 inches ; tail 2 - 4. Iris dark hazel ; 

 bill black, yellow at the base of the lower mandible; feet very light brown. 



Remarks on some points in the anatomy of this species by Mr. W. P. Pycraft will 

 be found in the Appendix to this paper, p. 454. 



[Riippell's Reed-Warbler was found on Ruwenzori from an elevation of 6500 to 

 13,000 ft. It frequented the undergrowth, especially where it was densest, and was 

 particularly numerous at about 10,000 ft., where the bottoms of the valleys were 

 swampy and full of low rank vegetation. Among this it was always to be found 

 creeping about and constantly uttering a single note, almost exactly like that of the 

 Hedge-Sparrow. Both B. cinnamomeus and B. barakce have also a loud short song of 

 stridulous notes, which they often utter with startling suddenness. One cannot fail to 

 remark the striking resemblance of the song of these two birds to that of Cetti's 

 Warbler {Cettia cetti), and their habits are exactly the same. Another marked point 

 of resemblance is the extraordinary development of the leg-muscles and the tough 

 wiry sinews — in fact, the three species are so much alike that one almost wonders 

 they should have been separated generically. — JR. B. W.~\

a, 2 . Mubuku Valley, E. Ruwenzori, 5000 ft., 5th April. [No. 2276. G. L.] 



Iris dark brown ; upper mandible black, lower slate-colour; feet brown. 



I have compared this bird with the type-specimen in the Tring Museum, which was 

 obtained by Emin at Njangabo, in Ndussuma, to the west of Lake Albert, and find that 

 they are quite similar. This species is new to the British Museum. 



[A single specimen of this rare Reed- Warbler was obtained by Mr. Gerald Legge on 

 the east side of Ruwenzori among the grass and dense vegetation below the forest-line 

 at 5000 ft. It had the great development of leg-muscles and wiry sinews noticed in 

 other species of the genus Bradypterus and in Schcenicola apicalis. — R. B. W.]

 Iris dark brown ; bill brown; feet dark grey or slate-blue. 



Professor Neumann, who has recently devoted much time and attention to the study of 

 this difficult group of birds, has referred both specimens in the present collection to a
