CHERRIE: ORNITHOLOGY OF THE ORINOCO REGION. 255 



neck ached with the strain of gazing upward when my 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 my 

 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 IMMUNDUS Sclater & Salvin. 



Lipaugus immundus Scl. & Salv., Nomencl. Av. Neotr., 1773. pp. 57, 159. 

 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 Nericagua 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.
