TWO NEW BIRDS FROM RORAIMA 



BY THOMAS EDWARD PENARD 



I HAVE two birds collected by Henry Whitely at Mt. Ro- 

 raima, British Guiana, which differ so much in size and color- 

 ation from specimens of allied forms collected elsewhere, that 

 I believe they represent two undescribed races. Through the 

 kindness of Mr. Outram Bangs both have been carefully com- 

 pared with specimens in the Museum of Comparative Zoology. 



It is usually not safe to base a new subspecies upon the evi- 

 dence of a single specimen; but in these cases I think the sepa- 

 ration is justifiable, when we consider not only the wholly 

 different appearance of the Roraima birds, but also the peculiar 

 geological area from which they came. 



Chloronerpes rubiginosus roraimae subsp. nov. 



Type, U. C. Z., no. 82,134 (collection T. E. P., 2002), adult 9 ; British 

 Guiana: Mt. Roraima, 3500 feet altitude; 27 December, 1883; Henry 

 Whitely. 



Subspecific characters. — Similar to Chloronerpes rubiginosus rubiginosus 

 (Swainson) of Cumana, Venezuela, but larger, and upper parts darker, not 

 so reddish. Similar also to Chloronerpes rubiginosus meridensis Ridgway 

 of Merida, Venezuela, and of about the same size, but under parts more 

 strongly barred, the markings on the belly wider, breast much darker, 

 contrasting strongly with the belly, the buffy markings very narrow,
