HYPUEOPTILA. 275 



Eab. Panama, Lion Hill (JfimmwaW'S"), Obispo Station (0. -S*.), Paraiso (Hughes^), 

 Chepo (Arce^). — Colombia 3; Venezuela ^ 



Lesson's type of this species was supposed to have come from Brazil ^, but it is now 

 known that the range of H. buffoni is limited to the north-western portion of South 

 America, where it is a common bird, and that it only enters our fauna as far as the line 

 of the Panama Railway, where M'Leannan^^ and others procured many specimens, 

 and where Salvin observed it in May 1873 near Obispo Station. 



If. huffoni has a near ally in H. ccBruleiventris, from which it differs in having the 

 under surface pure green instead of being deeply tinged with blue. 



The latter bird is found further inland in Colombia, and is sent in large numbers in 

 the trade collections of Bogota. 



H. huffoni seems to be strictly confined to the hotter parts of the countries it inhabits.

Rah. Panama ( Warszewiez ^). — N. Colombia. 



Warszewiez was the discoverer of this species ^. The single male specimen obtained 

 by him passed into Gould's hands, and was described in 1861. This type is said to 

 have been shot at Panama, but no other collector has met with it in that district. As 

 Salmon found it in the State of Antioquia, both near Medellin and Remedios, and as 

 Warszewiez also visited that portion of Colombia, it is just possible that the locality 

 Panama may be founded on a mistaken record of locality, and that Antioquia is the 

 only district in which this rare species is found. Salmon's birds were wrongly entered 

 as Chalybura buffoni in the list of his collection ^. 



E. urochrysea is closely allied to H. isaurce, but may be distinguished by the purer 

 ffreen colour of the throat.
