over the ear coverts, re-unites behind the ear covert, and is con~ 
tinued as a broad dark ill-defined half collar round the base of 
the neck. This is much more strongly marked in some birds 
than in others. The ear-coverts are white, many of the feathers 
dark shafted and spotted with brown or rufous brown. The 
chin and throat are white or creamy white, most of the feathers 
dark shafted and with a subterminal brown spot. ‘The whole 
breast, abdomen, sides, flanks, thigh coverts, uniform unspotted 
umber brown, some of the feathers very faintly margined paler, 
and on the breast somewhat darker shafted. ‘The vent and un- 
der tail-coverts white or dingy fawn, some of the latter with a 
subterminal pale brown blotch. The axillaries and lower wing 
coverts are mostly brown with occasional white spots or mott- 
lings, in some almost wanting. The inner webs of the prima- 
ries, except the terminal 2 or 3 inches, conspicuously marked 
with transverse spots of white or buffy white. Tail feathers, 
albescent below; all of them except the two centre ones, more or 
less noticeably barred on the inner webs, towards their bases, 
with white or buffy white. The thighs behind and interiorly 
white. 
In the adult, the white of the forehead is more conspicuous. 
The supercilium less so; the whole top of the head has a rufous 
east, the feathers being brown, darker shafted and broadly mar- 
gined, rufous. ‘There is a blackish brown line under the eye, 
but this is no longer quite continuous with the dark brown 
stripe, which proceeds from the gape under the ear coverts, and 
this latter again no longer (as in the young bird it often ap- 
pears to do) encircles the back of the ear coverts and joins into 
the dark collar. The dark brown stripe above the ear coverts 
which, in the young bird, is connected with the brown at the 
lower angle of the eye, in the adult no longer meets it, but 
commences at the hinder angle of the eye, and then produced 
backwards, widens into a broad ill-defined half collar, covering 
the whole back of the neck. ‘The whole of the upper parts are 
a sort of slaty brown colour, browner on the upper back and 
scapulars, the feathers dark shafted and paler margined ; the 
smallest coverts on the shoulder of the wings being often con- 
spicuously, though very narrowly, margined with white. The 
dark colour of the nape which, in some specimens, is almost 
blackish brown, shades gradually into the slaty brown of the 
upper back. ‘The chin, throat, cheeks and ear coverts, are 
almost perfectly pure white. The whole breast is pure white, 
but many of the feathers are darker shafted. The abdomen and 
sides are white, dark shafted, with a few linear drops of dark 
brown. Theflanks nearly unmottled brown, the thigh coverts slaty
