276 ZOOLOGICAL RESULTS OF THE E1WEXZOE1 EXPEDITION. 



beyond the occiput and is divided from the olive-yellow mantle by a bright yellow 

 collar ; the breast is orange-chestnut ; and the belly is mostly yellow, only the sides 

 and flanks being washed with orange-chestnut. 



The female of H. jacksoni is easily distinguished from the female of//, dimidiatus, 

 as the following comparative table of characters will show: — 



S. dimidiatus, J. H. jacksoni, $. 



General colour of the back and rump pale 



brown, the mantle streaked with black ; 



upper tail-coverts sandy-brown. 

 Throat white ; breast and sides of the body 



pale buff; middle of the belly aud under 



tail-coverts whitish. 



General colour of the back and rump olive, the 

 mantle streaked with black ; upper tail- 

 coverts bright olive-green. 



Throat and rest of the underparts pale yellow, 

 slightly washed with buff on the sides of 

 the body and flanks. 



[Antinori's Black-headed Weaver was plentiful all round the south end of 

 Ruwenzori below 5000 ft. and at Fort Beni. It was generally seen singly or in 

 pairs.— R. B. W.] 



The eggs of //. jacksoni are figured from specimens in the Jackson Collection 

 (PI. XIX. figs. 2, 4 (eggs)).

Adult female. Iris pale yellow or yellow; bill dark horn-colour or brown; feet 

 grey or slate-colour.

The Ruwenzori birds appear to be fairly typical examples of //. intermedius, but 

 the type from Abyssinia has the nape and occiput rather more strongly washed with 

 brownish-orange. The nearly allied II. cabanisi Peters, the southern representative 

 of the present species, has the occiput and nape bright yellow and appears to be a 

 perfectly distinct form. Captain Shelley, who does not keep the two forms separate, 

 has followed the ' Catalogue of Birds ' in referring certain specimens in the British 

 Museum from Lamu and Pangani to the southern form, H. cabanisi, which he says 

 is found south of the Equator ; but, in my opinion, they should really be referred to
