 uit het Natuurk. Tijds. Nederl. Indie, Deel xliii. Ail. 8.] 



Mr. Vorderman continues his notes on the birds of the

70. Wagler^s Six Ornithological Memoirs (reprint) . 



[Wagler's Six Ornithological Memoirs from the ' l-is.' Edited by

 library.

 capiUus is included as a species inhabiting Kamtschatka, the 

 only authority for so regarding it being, as far as I am aware, 

 a description of a young female Goshawk, referred by Mr. 

 Taczanowski to this species, which is given at p. 331 of his 

 paper just mentioned. 



So far as my experience goes, it is not possible to distin- 

 guish with any certainty yis^M/- atricapillus in the first year's 

 plumage from A. palumbarius at a similar age ; and I am
