meeting at the nape, the contrast between the margin and cen- 
tre is considerable, but in the parts previously enumerated, it is 
very slight, and might pass unnoticed by a careless eye. LHx- 
cept in the middle of the back, the white bases of the feathers 
scarcely show through any where. ‘The tail feathers are of two 
shades, the one set grey, asin No. 1, the others a sort of olive 
brown, with darker brown tips and wavy bars. ‘The ear coverts 
are pale rufous, each feather centered with dark brown. The 
whole of the chin, throat, breast, sides and abdomen, white, the 
feathers with broad central stripes (narrowest on chin and 
throat) of darkish umber brown, and many of those of the breast, 
sides and abdomen, with traces of somewhat paler brown bor- 
ders. The thigh coverts are mostly dull brown, with darker 
brown central stripes and with but a trace here and there to- 
wards the base of the tibia of white mottling. The tarsus fea- 
thers are pale fulvous brown, with darker centres and shafts. 
The smaller lower wing coverts in this, may be most properly 
said to be brown, with white patches, though some few, just 
about the carpal joint, are more white than brown. ‘There is 
much less white, and more of the rich dark brown about the 
whole lower surface of the bird’s body and wings than in No. 1. 
Of these, No. 3 was the oldest, and No. 2 the youngest bird.

My collection contains no egg of this species, and I haye 
never yet myself succeeded in finding a nest. My friend, Mr. 
hk. Thompson, furnishes me with the following notes :— 
“The breeding season commences in March, and lasts until 
the end of June, but they mostly lay in Apriland May. The nest 
is placed at.a height of from forty to fifty feet from the ground, 
on large trees, in dense woods, usually in a good game locality. 
The nest is a large round structure from 2°5 to 3 feet in diame- 
ter, much resembling that of the common Aquila Nevia, a thick 
clumsy platform, composed of thick dry twigs and roots, with a 
central depression from four to five inches deep, lined with fine 
roots, and stems. The eggs are usually two, but I have preserved 
no record of their appearance, and I have no specimens by me to 
measure or describe. ; 
“Our Moorhaitah or ‘ Peacock-killer’ as he is always called 
by the paharees, is a common bird in our province, (Gurhwal) 
they are known as famous destroyers of game, and many a fine
