.. BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 487 
lad. 2, Venezuela, Brazo Casiquiare, mouth of Cafio Atamoni, February 6, 
1931. ; 
1 ad. 2, Venezuela, San Antonio, Upper Orinoco, March 3, 1931. 
2 ad. o, 1 ad. 9, Venezuela, Cerro Yapacana, Rio Orinoco, March 20—April 
‘9, 1931. 
Zimmer’s observations on the plumages of this species (Amer. 
Mus. Nov., No. 893, 1936, pp. 8-10) are borne out by the present 
series and other examples examined. On the basis of his contention 
that the orange-rufous patch on the belly with the feathers tipped with 
black is a sign of immaturity, our specimen from Sao Gabriel would 
have to be considered as subadult. This one and the Brazo Casiquiare 
example have the colored tufts on the upper flanks yellow; the four 
from farther north have them orange-tawny, but this is apparently 
an individual and not a geographic variation. Zimmer found no 
geographic correlation to the variations of this character.

SPECIMENS COLLECTED 
1 ad. 2, Brazil, SAo Gabriel, Rio Negro, January 12, 1931. 
_2ad. 92, Brazil, Cucuhy, Rio Negro, February 38, 1930. 
There is considerable variation in even so small a series as three 
females. One of the Cucuhy birds is noticeably less yellowish green 
below and above, more sooty generally, than the other or the Sao 
Gabriel bird. It also has the gonydeal angle of the mandible paler 
than in the other two specimens. All the specimens are in abraded 
plumage. 
An additional specimen was taken at Chapozoa, on the Brazo 
Casiquiare, Venezuela, January 30, 1931, and was preserved in alcohol.
