chicks, extracted from eggs nearly ready to hatch off, would be 
at once distinguishable by their characteristic feet. 
Besides India, Burmah and Malayana proper, Wallace notes 
the occurrence of this species in Java, Sumatra, Celebes and 
Ternate; but it must be rare in the Archipelag 0, as our author, 
himself, has never met with it there.

BoneEwui’s HAGE. 
This Hagle, in the plains of India, lays in the latter half of 
December and in January; but in the Himalayas, it lays, I 
believe, in April and May. The nest is usually placed on 
ledges of precipitous earthen or rocky cliffs, and in the plains 
I think preferentially in the immediate neighbourhood of some 
large river or jheel. I have repeatedly seen their nests in the 
high clay cliffs of the Jumna and Chumbal in the Etawah 
districts, and I found a pair breeding in the ruined and 
eyclopean walls of the ancient Togluckabad, south of Delhi. 
Occasionally, however, they build on trees; and I found a nest

ority, but I have not the necessary works by me to enable me to decide this 
point.
