DESCEIPTION OF A NEW SUBSPECIES OF THE GENUS 

 PEUCEDEAMUS, COUES. 



By Egbert Eidgway, 



Curator of the Department of Birds. 



The specimens upon wbicli this new subspecies is based have long 

 been in the National Museum collection, baving been presented by Mr. 

 Osbert Salvin, who collected tliem in December, 1803. They, as well 

 as others from the highlands of Guatemala, have always x>assed as 

 Giraud's species; ^ but having compared them with Giraud's type, as 

 well as with a considerable number of specimens of the same species 

 from Arizona and Mexico, I find them to be quite different in the 

 respects pointed out below, and therefore entitled to subspeciflc sepa- 

 ration. 



PEUCEDRAMUS OLIVACEUS AURANTIACUS, new subspecies.

 smaller, and with head, neck, and chest very much brighter orange-
