CHERRIE : ORNITHOLOGY OF THE ORINOCO REGION. I79 



Contrary to Mr. Hellmayr's conclusions based on material from 

 Guanoco^ I do not consider R. a. capitalis a synonym of magnirostris 

 but a well marked race of atrosericeus and very readily distinguishable 

 from the former. Of the specimens secured two are adult males, one a 

 male in juvenal plumage, and two (probably) adult females. 



The females are almost as easily distinguished from the females 

 of R. c. magnirostris as are the males one from another. 



Adult female. Above dusky seal brown ; wings and tail more black- 

 ish; rump washed with bright chestnut; faintly vinaceous on fore- 

 head. Below, throat and upper breast bright bay, blending gradu- 

 ally into bright chestnut with a faint wash of dragon's blood red on 

 belly and sides. 



Immature male. A specimen taken July 31st is in transitional 

 plumage from juvenal plumage to what would correspond to the first 

 winter plumage of our northern Passeres. Above its head is dusky 

 brownish black; back bright reddish chestnut, produced by the broad 

 edges and tips to black feathers ; rump bright reddish chestnut ; wings 

 and tail brownish black; lesser, median and greater coverts narrowly 

 tipped and edged with chestnut; wing quills edged with chestnut on 

 outer webs ; below, throat dusky brownish ; remaining under parts 

 bright chestnut, washed with rufous on sides and flanks. Bill, in 

 life, dusky slate; feet dusky slate.

Not observed on the middle or lower river, but noted on the 

 upper Orinoco at Maipures from November to February during my 

 first expedition. 



This is the only species of tanager observed in the Valley of the 

 Orinoco that is not resident there.

Beebe secured an example of this species at Guanoco. It had 

 not been previously recorded from the Orinoco.
