upon the top of the head, chin and throat, and with such an 
admixture of down, that the dark skin, which in the hill bird 
(G. Himlayensis) shows so plainly through the scant covering, 
is, in this species, completely hidden. The nape and the 
whole of the neck, (except the back and side of the basal one 
fifth or less, which are bare or nearly bare,) are closely covered 
with dense, short, fur-like white, or dingy yellowish white, 
down. The crop patch is about the same colour as in the hill 
bird, (vide supra) but somewhat more rufous, and the whole of 
the rest of the plumage is a far more rufous, and deeper fawn or 
buffy brown than in G. Himalayensis. The lower plumage is 
in the adult of a rich rufous brown, bay, or even dull chesnut, 
conspicuously white shafted, whilst the mantle is a warm sandy 
brown, unlike the colouring of any of our other Indian 
Vultures. The feathers of the ruff are almost linear, (the web 
not so much separated as im the hill bird,) usually of a warm 
wood brown or rufous fawn, the feathers conspicuously paler 
centered. In one specimen, the old female shot by Mr. 
Marshall on the nest from which he took the egg, the ruff 
feathers differ in being of a uniform dingy white, faintly tinged 
with rufous. The upper back, the whole of the upper wing 
coverts, and all but the longest scapulars are a warm, wood 
brown, or brownish rufous fawn, yellower and sandier in some, 
deeper and more of a bay colour in others. The secondaries, 
tertials and longer scapulars umber- (but not dark umber-) 
brown, the latter (v/s. the longer scapulars) more or less tipped 
with the rufous or sandy colour of the upper back, which colour, 
in some specimens, more or less extends to the tips and outer 
webs of the tertiaries. Lower back, rump and upper tail 
coverts, the same colour as the upper back, but of a considerably 
lighter tint, in some mingled with brown, and in some 
altogether of a pure pale bay. The primaries and tail feathers 
are very dark brown, in some not so dark as the corresponding 
feathers in G. Himalayensis, but mm others of an intense 
chocolate brown. Lower parts a rich sandy or rufous fawn or 
even a deep bay, (the tint varies in different stages of plu- 
mage) each feather conspicuously paler shafted, and most of 
them (in the younger birds) conspicuously, though narrowly 
paler centred. The lineated appearance of the lower parts 
alone, at once distinguishes this species from the preceding 
one. 
The feathering of the tarsus is similar to that of G. Hima- 
layensis. 'This species, and not his Piwlvus, (our Himalayensis,) as 
Dr. Jerdon surmises, is doubtless the one to which Adams 
refers, under the name of G. Zndicus, and though his dimensions
