360 ZOOLOGICAL RESULTS OF THE RUWENZORI EXPEDITION. 



but in other respects they resemble the adult, which has the entire crown sooty black. 

 One male (No. 1112), apparently an old bird, has the black feathers of the crown separated 

 from the olive-coloured mantle by a narrow slate-grey collar. Another male (No. 1 L43) 

 has olive-green patches, instead of yellow, on either side of the black chest ; this also is 

 probably a character due to age, as the bird shows traces of the grey nuchal collar 

 referred to in specimen No. 1112. 



[The Masked Bush-Warbler was met with on Ruwenzori up to 9000 ft. and was 

 numerous in the forest-zone, almost always frequenting the tree-tops, though it was 

 also occasionally to be found among the undergrowth. — JR. B. W.~\

 [The Ruwenzori Bush-Warbler was met with from 6500 ft. up to 10,000 ft., but it 

 was rarely seen above 8500 ft. It was numerous in the forest-zone and lower margin of 

 the bamboos, and was always to be found skulking about among the dense undergrowth 

 or in some tangled mass of creepers hanging from the lower branches of a tree. This 

 species was never seen in the tree-tops, while the two other members of the genus 

 (A. personata Sharpe and A. affinis Grant) found on Ruwenzori frequent the tree-tops 

 almost entirely. — B. B. W.]
