BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 563 
The four specimens collected in June are in very worn plumage; 
the young male taken on December 4 is completing its tail molt and is 
otherwise in fresh plumage as are also the other December and late 
November specimens. The worn-plumaged examples are much whiter, 
less washed with tawny-buff on the breast and upper abdomen than 
are the three in fresh feathering. This may, to some extent, account 
for what Hellmayr (Catalogue of the birds of the Ninerienek pte we. 
1938, p. 28, footnote) refers to as ‘‘some local variation.”

SPECIMENS COLLECTED 
1 9, Brazil, Rio Cauabury, below mouth of Rio Maturac4é, Amazonas, Novem- 
ber 7, 1930.

1 9, Venezuela; Cerro Yapacana, Upper Orinoco, April 18, 1931. 
The birds collected in February and April were in breeding condition, 
the collectors having noted on the labels ‘‘active gonads.”’ 
This series exhibits fairly great variability in the size and stoutness 
of the bill and in the length of the wing (85 to 93 mm. in the males) 
but the variations are nongeographic. All the birds are adults. 
The Venezuelan specimens extend the range of this race to a new 
northern limit. Hellmayr (Catalogue of the birds of the Americas, 
pt. 11, 1938, pp. 46-47) does not include Venezuela in its range but 
writes in a footnote, ‘Whether the trade skins in the Berlepsch col- 
lection supposed to be from the ‘Orinoco delta’ really came from 
Venezuela remains to be corroborated.’’ The present two specimens 
from Cerro Guanari and Cerro Yapacana, while far from the Orinoco 
Delta in origin, yet are steps toward validating the data on the 
Berlepsch skins. 
These specimens have been compared with a good series of this 
race and with three adults of C. ¢. brasiliensis. 
An additional specimen, taken on the Rio Cauabury, November 7, 
1930, is preserved in alcohol.
