618 Mr. G L Bates on the 



because iu a large scries specimens \\\t\\ the plumage of 

 E. schistaceus are all adult males, and those with the 

 plumage of E. rufognlaris females (I had sent others before), 

 and because birds in all the different plumages have been 

 shot iu company with one another ; but because further 

 confirmation is found in two specimens in the Museum 

 (Nos. 2057 and 2141) previously collected by me at Bitye. 

 These were immature males^ and the plumage is similar 

 to that of the last three (Nos. 3301, 4021, & 3628) 

 in the series given above, but a few new slate-coloured 

 feathers are appearing on the throat, indicating the change 

 to the plumage of E. schistaceus. 



It is to be noted that immature males change, becoming 

 greyer above and whiter below, before the final change into 

 adult plumage. 



This species seems to me to have a different aspect, ou 

 account of its extreme slenderness, from either of the 

 species of Apalis which I know ; and its habits are different, 

 for it is a bird of the forest, and feeds in companies or bijak, 

 while Apalis hinotata and A. Jackso7ii have been seen in 

 small trees of open country, seeking their insects singly. 

 The separation into a separate genus, Eaprinodes, therefore, 

 seems to be a natural one.

A good many more specimens have been shot, for at 

 Bitye it is not a very rare bird. The black on the croji of 

 the males is more extended than in the females ; in the latter 

 there is only a black band running down the middle. The 

 colour of the iris in all is brownish-yellow. Young birds 

 (Nos. 3793-3889) have the heads above green like the back, 

 and the feathers of the throat and chest slate-grey with 

 white tips ; the inside of tlie mouth and tongue orange, the 

 latter with two small dark spots at the base near the edges.
