Very little is known of the habits of this Thrush beyond the fact that it 1s an inhabitant of 
Mr. Richardson has found it breeding at a height 
of 8000 feet. 
Adult male. Dark brown above, 
centre, and having whitish shaft-lines on those of th 
and lower back; the lateral upper tail-coverts white, with more or less black on the edges; lesser 
and median wing-coverts blackish-brown ; greater wing-coverts blackish-brown, externally buffy- 
whitish, forming a patch оп the wing ; bastard-wing black, with white shaft-lines to the feathers ; 
primary-coverts black; quills black, with a well-marked pattern, the primaries with a large white 
basal area to both webs, and a small white spot beyond the middle of the outer web on the second, 
third, and fourth primaries; the secondaries edged with white, and with conspicuous light grey 
tips; tail-feathers black, with a small white spot at the end, increasing in extent towards the outer 
feathers, the outermost having a white edging; lores dusky blackish, surmounted by a faint 
superciliary streak of ruddy brown; ear-coverts blackish, with narrow whitish shaft-lines ; sides 
of neck blackish-brown, with lighter brown centres and whitish shaft-lines, as on the hind-neck ; 
cheeks, throat, and fore-neck blackish ; centre of breast, abdomen, and under tail-coverts white, the 
sides of the body ashy-blackish, with white shaft-lines; on the sides of the lower flanks a black 
patch ; under wing-coverts and axillaries black with dusky bases; lower primary-coverts blackish 
like the under surface of the quills. 
Geocichline markings on the quills, white. Bill nearly black. Second primary about equal to 
the fifth. Feet and claws pale. Outer tail-feathers 0-2 inch shorter than the longest. 
Length of wing 5:4 to 5:1 inches, tail 3-45 to 8:15 inches, culmen 1:0 to 0°9 inch, tarsus 1:05 to 
0:95 inch ; bastard-primary shorter than the primary-coverts, its exposed portion measuring 0:8 to 
0:65 inch. 
Тһеге is apparently no difference to speak of between the summer and autumn plumage, but 
freshly-moulted birds are somewhat more tinged with ochraceous-buff on the abdomen and under 
paler on the head, with the feathers lighter brown in the 
e mantle, which become obsolete on the scapulars 
tail-coverts. 
There is considerable difference to be seen in the colour of. the flanks in the males, those 
obtained in February showing very little signs of dusky mottling, while one killed in April has the 
sides of the body almost as black as the throat. 
'The female is slightly paler than the male in colour, and the secondaries are edged with ashy- 
white. 
Young birds resemble the female as regards the wings and tail, having the secondaries edged 
with ashy-white, not pure white, as in the male. АП the feathers of the upper surface have ovate 
spots of ochraceous-buff, replaced on the back and rump by longitudinal chestnut centres to the 
feathers. The ear-coverts are black, with narrow buff lines below the eye; throat and chest, as well 
as the sides of the body, ochreous-buff, the feathers edged with black, producing a scaled appearance; 
the breast and abdomen paler, but equally mottled with blackish edgings to the feathers. 
A specimen from Amula, killed in September, has nearly moulted out of the mottled plumage. 
The Plate represents an adult male and female of the size of life, both drawn from the type 
specimens in the British Museum. The male has been already figured by Sclater (Cat. Amer. D.
