Thienemann, but furnishes no particulars. The figure repre- 
sents a somewhat broad, oval ego, of an uniform, pale bluish 
in, grey, tinged with brown, most strongly so on nape feathers, and with dark 
shafts. Cheeks and ear coverts grey, the feathers broadly edged with greyish 
white, so as to produce a striated appearance. Feathers of ruff, which as re- 
gards colour is very conspicuous greyish white, with narrow, central, grey 
streaks, back of the neck, below brownish grey patch of nape, greyish white, 
the feathers slightly darker shafted, and some of them with the greyish 
traces of faint, brownish grey, transverse, subterminal spots. The whole of 
the base of the neck behind, upper back and scapulars, a sort of ash grey, 
more or less tinged towards the tips with brownish grey, and the longer 
scapulars frosted with a purer grey. The middle and lower back, a shade 
lighter grey, the white bases of the feathers showing through, more or 
less. Upper tail coverts pure white, with regular, broad, transverse, grey 
or slightly brownish grey, bars. The whole of the wing coverts, winglet 
tertials, and outer webs of secondaries and last four primaries, grey, more silvery 
on quills, and browner on lesser coverts. The median coverts narrowly pale 
margined, and most of the other feathers of the corners narrowly paler tipped. 
The second, and last four primaries, have the central halves of the inner webs 
pure grey, and the marginal halves white The first primary is silver grey 
on the outer web, dusky grey on the inner, as far as the notch, and above this 
chiefly white. The next four are nearly black, with a good deal of silver grey 
however, on the outer webs of the first two, and of white, more or less mottled 
with dusky, on the inner webs of all towards the base ; the sixth is dusky grey 
on the outer web and tip, and paler and browner grey on inner web, which has 
a broad marginal stripe broadest towards base, where it occupies nearly the 
whole web, of white, irregularly mottled with grey. The central tail feathers 
are a uniform silver grey, slightly shaded, with dusky on the terminal half. 
The next feather, on each side, is similar, but there are six or five white patch- 
es on the shafts, and traces of corresponding, paler bars, on the inner webs, 
which are very narrowly, paler margined, in each succeeding feather, the 
white patches on the shaft are better marked, and extend further and further 
across the outer webs, while the corresponding broad pale bars,on the inner webs 
at first only mottled with white, become pure white, and larger, and at the 
same time, the white margin of the inner webs spreads inward, so that the 
two exterior feathers have the inner webs pure white, with only four or five, 
_ somewhat narrow bars of grey, or brownish grey, (which do not extend to the 
margin,) and here and there a little freckling, chiefly towards the base of the 
same colour. Chin, throat and front of the neck pearl grey, whitish on chin. 
Breast, abdomen, vent, sides, wing lining and thigh coverts pure white, 
with just the faintest possible grey mottling, or freckling, in places on sides, 
and base of thighs. Lower tail coverts white, with rather brownish grey, 
broad, incomplete, rather wavy, transverse bars; about one or two on each 
feather. Inner surface of the wings, mingled white and very pale grey, only 
the terminal 4 to 3 of the second to the fifth primaries, blackish brown. The 
first to the third quills are conspicuously notched on inner web, the second 
to the fourth, emarginated on outer webs. 
Female.—The lores dusky, covered with black bristle-like hairs, as is also 
the point of the chin. A patch (scarcely noticeable in some specimens) over the 
eye, and in front of it, white, tipped with brownish. Below the eye, and front 
of the ear coverts, somewhat purer, while a band, inside the ruff, from the base 
of the lower mandible, over the ear coverts to the sides of the nape, dark
