Dr. Reichenow regards II. camhurni Sharpe and H. jamesoni Sharpe as subspecies 

 of //. xanthoj^s. There can, however, be no doubt that the type of H. camburni, 

 from the Nairobi Forest, is a quite young male example of H. xanthops ; while the type 

 of //. jamesoni, from the Umvuli River, is a nearly adult male of the same species, 

 but with less yellow on the head. Captain Shelley has very properly united all under 

 H. xanthops, but at the same time he maintains that the southern form from south 

 of the Zambesi {R. jamesoni) is a greener bird, while that found to the north is brighter 

 and yellower (H. aurantiigula Cab. and H. camburni). The series in the British Museum 

 seems, however, to show that birds from the south when fully adult are almost, if not 

 quite, as bright as examples from the more northern parts of this bird's range. Of two 

 male birds collected by Mr. Carruthers at Lakes Kivu and Tanganyika respectively, 

 that from the former and more northern locality has the back greener and the crown 

 much less brilliant, the diff"erence being no doubt entirely due to age. 



[A few examples of Hartlaub's Golden Weaver were seen on the plains on the east 

 side of Ruwenzori. — B. B. W.] 



H-TPHANTOiusris CASTANOPS (Shelley). 

 Ploceus castanops Reich. Vog. Afr. iii. p. 96 (1904). 

 Xanthophilus castanops Shelley, B. Afr. iv. p. 471 (1905). 

 a,b. d 2. Fort Portal, 3500 ft., 5th July. [Nos. 3499, 3500. B. B. W.] 

 Iris very pale yellow ; bill black ; feet brown. 



The male, a very fine specimen, has the lores and chin black, and, in this respect, 

 differs slightly from any of the specimens in the British Museum or in the Jackson 

 Collection.
