5 subtus omnino sordide grisea, reotricibus duabus utrinque exfcernis griseo terminatis, fascia subterminali 

 obsoura. (Desor. maris et feminae ex Santa Fe, Panama. Mus. nostr.) 



Hah. Costa Eica, Talamanca {Zeledon, in U.S. Nat. Mus.) ; Panama, Boca del Toro (fide 

 Verreaux i), Santa Fe \ Santiago de Veraguas {ArcS). 



The single, somewhat immature, male specimen described by Gould under this name 

 was sent him by MM. Verreaux of Paris, who received it from Boca del Toro, on the 

 Atlantic coast of the State of Panama, near the frontier of Costa Eica ^. This type 

 remained unique for many years, until our collector E. Arce rediscovered the bird at 

 Santa Fe and other places in Central Panama, and sent us specimens of both sexes *. 



The range of the species would thus appear to be very limited, and confined to the 

 western parts of the State of Panama, and Talamanca, the border State of Eastern Costa 

 Eica. A little to the southward H. urochrysea takes its place, and to the northward 

 in the rest of Costa Eica and Nicaragua we find H. melanorrhoa. It is closely allied 

 to the first-mentioned bird, but may be distinguished by the bluisTi shade which over- 

 spreads the green of the under surface.

A series of specimens of this species from Eastern Costa Eica sent us by our collector 

 E. Arce were the first that reached us. These were described in the ' Proceedings of 

 the Zoological Society ' in 1864 under the name the species now bears \ The following 

 year Mr. Lawrence described the same bird, also from Costa Eica specimens, as 

 Chalybura carnioli ^. Other specimens have since been obtained in Costa Eica, where 

 the bird is now well known. It also occurs in Nicaragua, as Belt secured several 

 examples of both sexes at Chontales 2, and where Mr. Nutting also found it at 

 Los Sabalos*. 



Though clearly allied to both H. isaurce and H. urochrysea, this species may at once
