CHERRIK : ORNITHOLOGY 01* THE ORINOCO RIIGION. 22/ 



1907. The nest was saddled between the forks of a small branch at 

 the extreme top of a Chaparo Oak which stood in the open savanna. 

 It was about 6.10 m. from the ground. When found, one young bird 

 was perched on the edge of the nest but flew away and was lost when I 

 started to climb after the nest. The nest is a shallow, open, cup-shaped 

 affair, resembling somewhat nests of the wood-pewee {Myiochanes 

 virens), or more perhaps that of Pyrocephalns or Sublegatus. It is a 

 slight affair, loosely saddled in the forks, composed of rather short 

 pieces of fine grass stems and other vegetable fibres with which are 

 mixed many empty spider egg cases. The whole is held together largely 

 with spider-webs. The inner lining consists of a few feathers and more 

 empty spider egg cases. Outside it measures 2.8 cm. in depth by 6 cm. 

 in diameter; the nest cavity measures 1.3 cm. in depth by 4.2 cm. in 

 diameter.

Ornithion inerme Hartl., J. F. O., 1853. p. 35 (locality unknown^) ; Ber- 

 lepsch & Hartert, p. 42 (Suapure, Caura River, Venezuela). 



Rare. Not observed by the writer (on first trip), but in Berlepsch 

 and Hartert's paper a single specimen is reported collected at Suapnre on 

 the Caura River by Klages. In the Brooklyn Museum is a specimen 

 collected by the writer at Maipures in December, 1905. In this example 

 the eye was clay color; bill above black, below slate color; feet blackish 

 slate.
