9 subtus omnino sordide grisea, rectricibus duabus utrinque externis. griseo terminatis, fascia subterminali 
obscura. (Descr. maris et femine ex Santa Fé, Panama. Mus. nostr.) 
Hab. Costa Rica, Talamanca (Zeledon, in U.S. Nat. Mus.) ; Panama, Boca del Toro (fide 
Verreaux 1), Santa Fé 4, Santiago de Veraguas (Arcé). 
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 Ricat. This type 
remained unique for many years, until our collector E. Arcé rediscovered the bird at 
Santa Fé and other places in Central Panama, and sent us specimens of both sexes 4. 
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 
Rica. A little to the southward H. urochrysea takes its place, and to the northward 
in the rest of Costa Rica and Nicaragua we find H. melanorrhoa. It is closely allied 
to the first-mentioned bird, but may be distinguished by the bluish shade which over- 
spreads the green of the under surface.

A series of specimens of this species from Eastern Costa Rica sent us by our collector 
E. Arcé 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 Rica specimens, as 
Chalybura carnioli®. Other specimens have since been obtained in Costa Rica, where 
the bird is now well known. It also occurs in Nicaragua, as Belt secured several 
examples of both sexes at Chontales?, and where Mr. Nutting also found it at 
Los Sabalos 4. 
Though clearly allied to both H. tsaure and H. urochrysea, this species may at once
