BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 549 
Orinocoan race pileata and has demonstrated the conspecificity of 
trinitatis and chlorotica. Far from being two species, the forms are 
not too well marked even as subspecies. 
The Soledad specimen is a young bird molting into adult male 
plumage; the nape and upperparts of the body and wings are still 
green sprinkled with new dark blue feathers, and the underparts are 
completely adult in appearance.

Hellmayr (Catalogue of the birds of the Americas, pt. 9, 1936, 
p. 58, footnote) writes that males ‘from the Orinoco region, Rio 
Negro, Rio Madeira, and Rio Xingti, when compared to a series from 
eastern Ecuador and Peru, have the median underparts and the 
lower tail coverts deeper orange-rufous, and the sulphine-yellow 
lateral area in females is brighter as well as more extensive,” and 
suggests that subdivision of this race might be justified. This should 
be reflected in the present series, which has been compared with a 
series of four adults of each sex from eastern Ecuador, kindly lent 
me by the American Museum of Natural History, but I cannot see 
the differences alluded to above. 
TANAGRA PLUMBEA (Du Bus): Plumbeous Euphonia 
Euphonia plumbea Du Bus, Bull. Acad. Roy. Sci., Lettr. et Beaux-Arts Belgique, 
vol. 22, No. 1, 1855, p. 156 (“la Nouvelle Grenade,” errore?). 
SPECIMENS COLLECTED 
2 ad. o&, 1 ad. 9, San Antonio, Upper Orinoco, Venezuela, March 1-2, 1931. 
lad. o&, 1 ad. 9, Cerro Yapacana, Upper Orinoco, Venezuela, April 6, 1931. 
Because of the rarity of this species in collections and the fact that 
the present five specimens appear to be the first ones recorded from 
the Upper Orinoco Valley, it may be of interest to give their measure- 
ments: Males—wing 48.2-49.5 (48.8); tail 26-26.8 (26.4), culmen 
from base 7.7-8.0 (7.8 mm.); females—wing 46.4—47.3, tail 26.9-27.0, 
culmen from base 7.0-7.5 mm. A female from Valle de los Monos, 
Mount Duida, is somewhat larger, especially in the bill—wing 48.5, 
tail 27.2, culmen from base 9 mm. Birds from British Guiana agree 
760001—48——12
