palms in flights, composed of members of its own specieSj or mixed 

 up with individuals of Calliste schranki, Calliste cyaneicollis, and 

 other birds of this genus. The Yuracares Indians call it " yeni 

 yeni" from its peculiar call-cry ; whence MM. Lafresnaye and 

 d'Orbigny gave its present scientific name. 



VonTschudi found this Tanager in the hot wood-region of Eastern 

 Peru, and the collections formed by Mr. Hawxwell on the Ucayali 

 in 1852 likewise contain examples of it; so that we may assume that 

 it ranges over the whole of the vast wood-regions of Peru and Bolivia, 

 representing in these parts the Calliste tatao of Guiana, and the 

 Calliste ccelicolor of New Grenada. 



It may be easily distingviished from both these species, which 

 in general colouring it closely resembles, by its pure brilliant red 

 lower back. 



I am not acquainted with the female of this Tanager, but believe 

 it will be found to differ very little from the male.
