Obs. Mr. Wallace was quite right, in m}^ opinion, to separate this 

 bird, which is a large edition of A. hior/aster. It is, however, not 

 strictly allied to that bird as regards its wings, which are distinctly 

 barred on the under surface. Independently of its uniform appear- 

 ance above, and the want of the rufous nape-band, it can always be 

 told from A. f/riseof/ularis by its much shorter middle toe, which 

 measures only 1-3-1 -4 inch without the claw against 1-65-1 '7 inch 

 in the other species (females measured).
