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-black. The sides of the head are 

 singularly varied ; the lores have a fulvous- white 

 line, but the lower half of the eyelids are black : 

 I another similar line begins behind the eye and 

 passes over the ears, which are black ; the ear is 

 1 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 

 I 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 



I 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- 



i covered ; the under mandible of the bill and the legs 



I'are so very pale as to be almost white.
