This species was not seen on the Orinoco proper, but Beebe took 

 specimens at Guanoco in the delta region and I collected a single 

 example May 26, 1907, at La Cascabel on the river San Feliz near its 

 junction with the Cuchivero River. 



The Tring Museum received specimens from Suapure, La Pri- 

 cion, Nicare and La Union on the Caura River. 



In the American Museum collection are specimens collected on 

 the Caura River by Klages at El Llagual in March, Suapure in Janu- 

 ary and La Union in October. 



In the La Cascabel specimen, an adult male, the eye was seal 

 brown; bill above black, sides of mandible slate grey, center of ridge of 

 gonys black ; feet slate grey.
