 stripe, cutting off a yellow superciliary stripe ; lower throat and whole breast and sides thickly 

 streaked with black ; yellow of throat sometimes tinged with orange-brown ; that of belly and

 and yellow black-striped under parts, but easily recognized at maturity by the orange-brown 

 ear-coverts ; possessing also the charm of rarity in most parts. It is also remarkable for the 

 curved and very acute bill, and some anatomical pecuUarities of the tongue, which have caused
