CHERRIE: ORNITHOLOGY OF THE ORINOCO REGION. 255 
neck ached with tlie strain of gazing upward when m}' eye caught a 
glimpse of a good-sized, dark-colored bird alighting on a bare branch 
only about 3 meters from the ground and about 9 meters from where 
I stood. For an instant I forgot the enticing whistles and gave m}^ 
attention to this quiet dweller of the forest. As I looked the body 
stiffened and its owner sat up sharply erect, the bill opened and the 
mystery of those notes that had so thrilled me and brought every sense 
into unison was solved. This modestly dressed piper was the master 
ventriloquist.

Lipaugus simplex immundus Berlepsch & Hartert, p. 57 (Nericagua and 
Perico, Orinoco River, Suapure and La Pricion, Caura River). 
Rare. This species, on my first expedition, was observed and 
collected at Perico and Kericagua only. Berlepsch and Hartert 
record Tring Museum examples from La Pricion and Suapure on the 
Caura River, and in 1907 the writer observed and collected specimens 
at La Cascabel on the San Feliz River near its junction with the 
Cuchivero River. 
Eye bay brown; bill black; feet slate color. 
A male collected at La Cascabel, May 26, 1907, has a distinct nar- 
row greyish collar extending completely around the neck.
