cherrie: ornithology of the Orinoco region. 267 
Beebe collected two specimens at Guaiioco, in the delta region, 
that are inseparable from the Brooklyn Museum series of A', siisunans 
susiirraiis from Carenage, Trinidad. The characters cited by Hell- 
mayr in his Birds of Trinidad as distinguishing the birds of the 
Orinoco delta from those of Trinidad, do not seem to be constant, 
one of Beebe's specimens having the throat as whitish (not buff) as 
any example from Trinidad. Beebe's other specimen showing con- 
siderable bufT on throat and remaining light spots on under parts is 
readily matched by Trinidad specimens. 
This species was not observed by the writer.

Rare on the lower Orinoco from Altagracia and Caicara up as 
far as the first falls, but common from the vicinity of Maipures 
onward. On the 1907 expedition, observed and collected on the San 
Feliz River near its junction with the Cuchivero River, and included 
in the Berlepsch and Hartert paper from Suapure and La Pricion on 
the Caura River. 
In the American Museum are Caura River specimens collected 
by Klages at Suapure and fhe mouth of the Malo River.
