f. cT . Fort Beni, Semliki Valley, 3000 ft.. 9th Aug. [No. 3536, R. B. W.] 



g. Imm. Mpanga Forest, Fort Portal, 5000 ft., 20th Sept. [No. 549. R. E. I).] 

 Adult male. Iris brown or dark brown ; bill black ; feet grey or bluish-brown. 

 Adult female. Iris light or dark brown ; bill black; feet, grey or slate-colour. 

 Immature. Bill dusky (pale horn-colour in skin). 



In the oldest male examples the back is deep black like the broad nuchal band with 

 which it is confluent, and the feathers of the rump and upper tail-coverts are mixed 

 with black and olive. In younger male examples the back is strongly washed with 

 olive and contrasts more or less sharply with the black nuchal band ; the rump and 

 upper tail-coverts are olive. 



[Vieillot's Black-and- Yellow Weaver was not uncommon in the forest near 

 Fort Beni and was also met with in the Mpanga Forest. It has a very remarkable 

 double note, both soft and musical, like the striking of two or three glass finger-bowls 

 at the same time. — R. B. W.~] 



ClNNAMOPTERYX MPANGA Grant. 



Cinnamopteryx mpanga Grant, Bull. B. O. C. xxi. p. 15 (1907). 

 a. 6 . Mpanga Forest, Fort Portal, 5000 ft., 20th Sept. [No. 3591. R. B. W. 

 Type of the sjjecies.] 



This species is most nearly allied to C. tricolor (Haiti.), but the black on the head 

 is continued on to the nape and the yellow band across the upper mantle is much 

 narrower, being confined to three or four series of the shorter feathers, which are 

 merely tipped with yellow and have the blackish basal portion separated by a white 

 band. Iris dark brown ; bill black ; feet dark brown. Total length ca. 6 inches ; 

 culmen 0-8 ; wing 35 ; tail 2*05 ; tarsus 0'9. 



Since I described this Weaver I have recently examined three males of this species 

 procured by Mr. Jackson's collectors in the Kibera Forest, Toro. Two agree in all 

 respects with the type, but in the third specimen the yellow band across the mantle 

 is rather wider, and in this respect approaches the West-African C. tricolor. 



[A single example of this Chestnut Weaver was obtained in the Mpanga Forest, 

 east of Ruwenzori. It was one of a pair which had a nest suspended at ihe end of a 

 thin bough, about 60 ft. from the ground. The nest was about three parts finished by 

 the middle of September, when we moved our camp. Unfortunately we failed to 

 obtain the female. — R. 11. J J".]
