the Tanagers were, as I am informed, issued in the latter part of 

 the year 1850, I think Dr. Cabanis' name is more properly applicable 

 to this species, and ought to take precedence over my own. 



This bird is common in Bogota collections, and is doubtless of 

 frequent occurrence in the mountain-valleys of New Grenada, where 

 those collections are formed. I have never seen it from any other 

 locality. 



The New-Grenadian Rufous-headed Tanager may be distinguished 

 from Calliste cayana by the greenish colouring of the back and 

 under-plumage. It is also of slightly larger dimensions, and has a 

 well-defined red cap, while in C. cayana this colour passes gradually 

 into the yellow of the nape.
