the upper. The inside of the wings and the axil- 
lary feathers are both of a uniform unspotted cine- 
reous grey. 
The under plumage may be described in fewer 
words. From the chin to the breast the colour is 
of the same buff-yellow or isabella tint which is the 
ground colour of the upper plumage ; the chin itself 
is paler and inclined to white ; this colour is bounded 
just below the breast by three semi-circular bands ; 
the first is rich chestnut, — the second, white, — and 
the third, black, each being about four-tenths of an

with black and greyish-white, the former colour 
predominating on the belly, but the latter on the 
flanks and thighs ; tarsi feathered to the toes, and of 
an unspotted grey ; bill yellow ; feet brown.

manner. There is no black in front of the head, 
and the white patches are so tinged with fulvous 
that they can scarcely be traced ; the upper part of 
the neck and its sides are banded with blackish- 
brown ; there are no bands on the breast, and the 
inner wing-covers are dark on the middle ; the lesser 
wing-covers, which in the male are pure fulvous, are 
here obliquely traversed by slender black lines. All 
the scapulars and most of the tertial quills are dark 
vinaceous rufous, upon which the black bands are 
broad and close, leaving the margin of the feathers
