BUBONIN-. to 
of mid-claw slightly dilated ; irides, in some brownish-yellow, in 
others, dark-brown ; in one nearly pure yellow; bill, upper man- 
dible, dark-brown, lower mandible paler, especially towards the 
chin ; cere dusky-greyish. 
A prominent tuft of disunited, webbed, bristly, white feathers 
(with dark naked tips to the shafts, and traces on those nearest 
the eye of dark cross bars), on each side of the upper mandible at 
its base; a faint tinge of buffy at the anterior angle of the eye ; 
rest of lores, feathers below and behind eye, including ear-coverts, 
loose, webbed, silky, greyish-white, with traces of faint minute 
transverse brown bars; chin white, the feathers of the extreme 
tip somewhat bristly and curving upwards round lower mandible ; 
across the throat and upwards immediately behind the ear orifice, 
as far as the base of the aigrettes, a band of creamy or pale butf 
feathers, with numerous minute, transverse, wavy brown pen- 
cillngs and bars; those from the aigrettes to the sides of the 
throat with conspicuous dark-brown tippings, which form the 
defining line of the disc, and a few of those in the centre of the throat 
with similarly colored spots at the tips; forehead and a broad 
supercilium running up the inside webs of the aigrette feathers, 
and a curved band at the back of the head, extending from the 
point of one aigrette, to the point of the other (when laid: flat. on 
the head) a silvery-grey or greyish-white, the feathers with dark 
brown shafts, and numerous minute, transverse pencillings of that 
color, and some of them with terminal spots; centre of forehead 
and top of head, and a triangular space surrounded by this grey 
band, a rich dark brown; purest on the centre of the forehead, 
with small twin spots or imperfect transverse bars and mottlings, 
to a greater or lesser extent, of pale buff; the outside webs of 
the aigrettes are similar, as are the feathers of the band outside, 
and contiguous to the curved grey band, which latter seems con- 
tinuous with the dark line of the outer webs of the aigrette, while 
the former seems to start immediately above the centre of the 
eye; below the dark band, at the base of the neck, is another 
band of very similarly marked feathers, but whereas the dark 
brown predominates in the former, the buff much predominates in 
the latter; the back, rump, upper tail-coverts, scapulars, wing- 
coverts, (except the greater ones of the primaries) a mixture of 
pale brownish-grey and pale buffy, with dark brown central 
streaks, and numerous transverse, wavy brown pencillings and 
_ mottlings. 
In the outside line of the scapulars, the buff is very pure, and 
in some positions conspicuous, and while the rump, upper tail and 
lesser wing-coverts, are dingier and greyer, the centre of the upper 
back and the median and secondary wing-coverts show more of a 
pale buff; the primary greater-coverts are very dark-brown, with 
broad transverse buffy mottled bars; the quills are darkish-brown, 
with numerous broad transverse greyish, more or less dingy 
white bars, much more conspicuous on the outer webs; with the
