CHERRIE: ORXITHOLOGV OF THE ORINOCO REGION. 183 
A male in that collectiim taken September 9, 1901, is in the plumage 
of the female. 
The adult males from the Caura River differ from "Brazil" and 
"Bahia" skins, in the same collection, in having the white feathers of the 
ui)per breast and sides prominently marked with subapical v-shaped black 
bars. A specimen from Jungus, Bolivia, agrees in this respect. The 
"Brazil" and "Bahia" skins have the entire breast and belly strongly 
washed with pale lemon or sulphur yellow, the subapical bands dusky, 
and not at all prominent. .Above, these birds have a brownish wash 
while the Suapure birds have a faint bronzy green wash an.l are also 
noticeably smaller. 
N^ot noted on the Orinoco but recorded from its tributary, ihe 
Caura River, from Suapure and Nicare, by Berlepsch and Hartert.
