" Iris dark red, feet dark grey, bill black." 



These birds are identical with Bogota-skins in the collection of 

 the Munich Museum. Like the latter, the males have a broad 

 scarlet supra-auricular stripe, and the lesser upper wing -coverts 

 bright lemon-colour. 



IT. xanthopygius ranges from N.W. Colombia (Truando) south- 

 wards to S.W. Ecuador, where a specimen was obtained by 

 Dr. Siemiradzki in the vicinity of Chimbo *. In Panama and 

 Eastern Costa Rica it is represented by the nearly allied, and 

 perhaps only subspecifically distinct H. 7'ubrifrons Lawr.t 

 Although considered by Salvin J to be inseparable from H. xan- 

 thopygius of Colombia, two birds from Veragua and Chiriqui 

 are so much smaller (wing 78, 80 ; tail 58 mm.) than any of 

 the numerous (about fifteen) specimens of the southern form, that 

 there can be scarcely any doubt as to their distinctness. More- 

 over, in H. ruhrifrons the sexes are alike, the male lacking the 

 scarlet supra-auricular stripe as well as the yellow patch on the 

 lesser wing-coverts. Cfr. liidgway. Bull. U.S. Nat. Mus. no. 50,
