CHERRIE: ORNITHOLOGY OF THE ORINOCO REGION. 183 



A male in that collection 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 

 upper 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 and are also 

 noticeably smaller. 



Not noted on the Orinoco but recorded from its tributary, the 

 Caura River, from Suapure and Nicare, by Berlepsch and Hartert.
