YELLOW-CRESTED FLAT -BILL. 159 
young and female of the present species the yellow 
crest is not developed. 
The upper plumage, when the crest is concealed, 
is entirely of a rich and full drab-brown, having a 
strong fulvous tinge on the back, which becomes 
almost ferrugineous on the margins of the wing- 
covers and the quills, both which, with the tail, are 
light brownish-hlack. The sides of the head are 
singularly varied; the lores have a fulvous- white 
line, but the lower half of the eyelids are black: 
another similar line begins behind the eye and 
passes over the ears, which are black ; the ear is 
bordered below by another pale line, beneath which 
is another of black, which commences at the base 
of the lores, passes immediately under the eye, and 
is separated from the black of the ears by the pale 
line already noticed. The under plumage is of a 
fulvous-yellow, except the chin and throat, which 
are white ; but the sides are tinged with yellow ; 
the inner wing-covers are like the breast, but the 
thigh-feathers, except those close to the joint, are 
almost black. The yellow spot on the crown is 
very pure, but the tips of the feathers are of the 
same brown as the rest of the plumage, so that, un- 
less they are raised, the crest would not be dis- 
covered ; the under mandible of th.e bill and the legs 
are so very pale as to be almost white.
