30 PENARD BIRDS FROM RORAIMA Pv^i^V^lF' 



throat with less white, upper parts darker oUve green, not so yellowish 

 or reddish. 



Measurements. — Type, adult 9: wing, 122.5; tail, 74.0; tarsus, 20.0; 

 culmen from base of forehead, 27.0 mm. 



Following Ridgway's key to the species and subspecies of 

 Chloronerpes (Birds of North and Middle America, 1914, VI, 

 p. 125), the Roraima bird falls into the rubiginosus group, in the 

 first section, with wings from 114 to 133.5 mm., containing 

 yucatanensis, nropygialis, meridensis, and alleni, while true ru- 

 biginosus, a much smaller bird, belongs in the second section, 

 with wings from 98 to 115 mm. Chubb (The Birds of British 

 Guiana, 1916, I, p. 483) describes and gives measurements of 

 a male and a female, collected on the Anarika River. The 

 measurements (wing, d', 116; 9, 113) indicate a comparatively 

 much smaller bird than C. r. roraimae, probably true rubigi- 

 nosus, under which name Chubb Hsts the British Guiana form. 

 He includes also Mt. Roraima, 3500 ft., and Merume Moun- 

 tains in the range. It would seem, therefore, that two forms 

 are represented in British Guiana, one inhabiting the lowlands, 

 and the other the more mountainous sections, of which Roraima 

 forms a part. 



Tanagra violacea rodwayi subsp. no v. 



Type, M. C. Z., no. 82,135 (collection T.E.P., 2001), adult d"; 

 British Guiana: Mt. Roraima, 3500 feet altitude; 1 January, 1884; 

 Henry Whitely. 



Subspecific characters. — Similar to Tanagra violacea violacea (Linn6) of 

 Surinam, but larger, and upper parts more violaceous, less bluish. Similar 

 also to Tanagra violacea pampolla Oberholser ( = magna of authors) of 

 southeastern Brazil, and of about the same size, but the bright violet 

 coloration extending with uniform intensity over the entire upper parts, 

 including the lower back and upper tail coverts, instead of being restricted 

 to the head, neck, and upper back.
