50 BUTEONIN A. 
?. Length, 186 to 19°5; expanse, 41°8 to 43:9; wing, 15 to 
16; tail, 9°87 to 10°5; tarsus, 2°28 to 2-46; bill from gape, 1:07 
to 1:2. 
Male : above throat and breast darkish blue-grey, darkest on 
the back; the first six quills black, the next one lighter, changing 
to grey ; secondaries grey, with a black bar; tail grey, the outer 
two feathers barred on their inner webs with bright rufous, the 
other three with dusky ; belly, vent, under tail-coverts, and under 
Wee es white, with bold dashes of rich chestnut or reddish- 
rown. 
The female chiefly differs from the female of the last in color, by 
the lower parts being whiter, and the streaks much larger, and 
more rufous-brown. 
Such is Jerdon’s description. To this I add Mr. Hume’s 
description, which is much more detailed and is taken from his 
“ Scrap Book.” 
Description.—Legs and feet yellow ; claws black ; irides bright 
yellow in the adult, sometimes brownish-yellow in the female, 
almost white in one young one examined; bill black, dusky 
in the young; cere greenish-yellow, yellower in the young. 
Plumage, Adult Male.—The whole head, chin, threat, neck all 
round, breast, back, scapulars, wings, (except the first seven 
primaries which are blackish), and central tail-feathers grey, of 
different shades; the neck, cheeks, and ear-coverts bluish ; 
crown of the head and occiput (below which there is a white 
mottled nape-patch, owing to the white bases of the feathers 
showing through), here and there tinged with rufous brown; the 
scapulars infuscated and brownish; the back darker and more 
ashy, and the wings and centre tail-feathers more silvery; the 
secondaries have a broad, blackish, transverse band across both 
webs, forming a conspicuous wing-band (not unlike that of the 
common pigeon C. intermedia), and with traces of another, or 
in some specimens, two other bands on the inner webs; the 
central tail-feathers unbarred, the laterals with four very broad, 
transverse, dark bars on the inner webs, and traces of the same 
on the outer webs of some of the feathers, the grey fading as 
the feathers recede from the central ones, and to pure white on 
the exterior ones, and the dark brown bands changing gradually 
to dull chesnut on the latter; -a broad circle round the eye 
whitish ; the lower parts from the breast downwards, and the 
whole wing-lining (except a few of the longer lower-coverts, which 
are ashy-grey with large white spots), pure white; the feathers 
of the abdomen with narrow, rather pale chesnut central streaks ; 
there are lanceolate chesnut dashes in the wing-lining ; the axil- 
laries are broadly and irregularly barred with blotches, and lower 
tail and thigh-coverts have the shafts of the same color, afew 
faint streaks of which are also generally to be seen mingling 
with the blue-grey of the breast. 
Adult Female.—Forehead, and a band round the -eye, slightly
