The differences between collingwoodi of Trinidad, Tobago, northern 
Venezuela, and up the Orinoco Valley to Puerto Ayacucho and the 
Caura Valley, and aurulentus of Santa Marta to the Lower Rio Magda- 
lena, Colombia, as pointed out by Zimmer (Amer. Mus. Nov., No. 
1045, 1939, p. 16) hold in the material studied together with the pres- 
ent series, although they are rather slight. The present race averages 
darker, less clear yellow and green than aurulentus. 
Another example from Puerto Ayacucho, January 3, 1930, was 
preserved in alcohol.

The Brazilian adult female has a slightly broader bill than any of 
the Venezuelan specimens. 
In his notes on this species Zimmer (Amer. Mus. Nov., No. 930, 
1937, p. 26) states that four specimens collected at Chamicuros, 
Peru, and now in the British Museum, are the only Peruvian examples 
recorded. It may be noted that there is a specimen from Pebas, 
Peru, collected by Orton, in the United States National Museum 
(No. 55325). The bird has no date on the label but was cataloged 
in the Museum in June 1869.
