 brownish black underside [of wings and tail?], rump and upper tail- 

 coverts magnificent topaz orange; bill, bluish. Total length, 158.7;

Isthmus of Panama. 



It is quite impossible to tell from the ver}'^ unsatisfactory description 

 quoted above just what the characters of this species are. Judging 

 from the name it would seem that there must be some orange or yellow 

 about the wings, but the description does^ not say so; possibly by 

 "underside" (second mention of this term) is meant the under wing- 

 coverts. Should there be really yellow on the wings, even, on the 

 underside, the species would be distinct enough. Otherwise, it seems 

 to resemble H. chrysonotus,^ from central Colombia, which, however, 

 has the wings and tail wholly black, even on the "underside."

 (State of Panama, Colombia; coll. A. Boucard). 



' According to Mr. Cherrie the bird breeds in this plumage. An immature male in 

 the collection of the United States National Museum differs from Mr. Cherrie' s descrip- 

 tion in having the head hair brown (much deeper on pileum) instead of slate-black or 

 slate-gray, in having the breast dull orange chrome instead of ochraceous-rufous,and 

 the rump light yellowish olive, with tips of the feathers broadly dull orpiment orange, 

 the upper tail-coverts being uniformly of a rather deeper shade of the latter color.
