Uniform black ; crest orange ; nnder wing-coverts dull black ; 

 bill and feet black: whole length 5-5 inches, wing 3, tail 2-5. 

 Female. Above black ; head and neck and body beneath dark oli- 

 vaceous brown, rather lighter on the throat ; flanks and crissum 

 blackish. 



Bah. Costa Pdca, Veragua, Panama, Colombia, and N. Ecuador. 



The black under wing-coverts isolate this species. Fraser's female 

 from Pallatanga, Western Ecuador (_y), may possibly belong to 

 another species, but the bii'd certainly reaches as far south as Paste 

 (see specimen Ic).

 Creurgops, Scl. P. Z. S. 1858, p. 75 C. verticahs. 



The median commissural notch is well developed in this form, and 

 there are scarcely any signs of rictal bristles. In other respects 

 Greuryops comes near to the preceding genus. The type is only 

 known from Colombia and Ecuador.
