8400 feet above the sea. Mr. Ferrari-Perez has also procured an example at Tezinüan in the
province of Puebla in November, hut the principal information as to the range of the species is
contained in the list here given of the series in the Salvin-Godman Collection.
Very little is known of the habits of this Thrush beyond the fact that it is an inhabitant of
the pine-woods in the highlands of Mexico, where Mr. Richardson has found it breeding at a height
of 8000 feet.
Adult male. Dark brown above, paler on the head, with the feathers lighter brown in the
centre, and having whitish shaft-lines on those of the mantle, which become obsolete on the scapulars
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 bufiy-
whitish, forming a patch on 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 blackisb, 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, th e'
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 3T.5 inches, culmen L0 to 0’9 inch, tarsus 1*05 to
O’9-5 inch; bastard-primary shorter than the primary-coverts, its exposed portion measuring 0*8 to
0-65 inch.
There is apparently no difference to speak of between the summer and autumn plumage, but
freshly-moulted birds aré somewhat more tinged with ochraceous-buff on the abdomen and under
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. All 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. B.
