Above brown ; head black ; broad superciliaries, joined by a line 

 round the nape, white : concealed vertical crest orange or yellow ; 

 wings and tail blackish brown, with slight rufous or whitish edgings 

 more or less apparent : beneath bright sulphur-yellow ; throat white ; 

 under wing-coverts sulphur-yellow ; inner margins of wing- and 

 tail-feathers pale rufous ; bill and feet black : whole length 8-5 

 inches, wing 4-6, tail 3 - 2. Female similar, but concealed crest 

 yellow or wanting. 



Hah. Southern Mexico, and Central and South America down to 

 Paraguay. 



After examining a large series of specimens of this species, I have 

 como to the conclusion that they may be all safely united under one 

 name. It is quite true that in Mexican specimens, as pointed out 

 by Lafresnaye, the bill is rather longer and not so widened and the 

 size is smaller ; but specimens from intermediate localities show an 

 intermediate structure, and it is not possible to draw a satisfactory 

 line of demarcation between the two forms. Nor do I now think 

 it advisable to keep the form of Western Ecuador, which I formerly 

 called M. chrysogaster, apart.
