CHERRIE : ORNITHOLOGY OF THE ORINOCO REGION. 267 



Beebe collected two specimens at Guanoco, in the delta region, 

 that are inseparable from the Brooklyn Museum series of X. susurrans 

 susurrans 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 buff on throat and remaining light spots on under parts is 

 readily matched by Trinidad specimens. 



This species was not observed by the writer. 



XlPHORHYNCHUS LINEATOCAPILLUS (Bed. & Lever.). 



Dendrornis lineatocapilla Beriepsch and Leverkuhn, Ornis, 1890: p. 24

 Dendrornis pardalotus Beriepsch & Hartert, p. 64. 



Rare, seen only on the upper river where three specimens were 

 taken during March and April at Nericagua. 



Beriepsch and Hartert report specimens collected at Suapure and 

 at La Pricion on the Caura River. 



The American Museum collection contains specimens from La 

 Union and Suapure on the Caura River that agree with Brit. Guiana 

 specimens. There are also examples from the foot of Duida (Miller Col.). 



XlPHORHYNCHUS OBSOLETUS NOTATUS (Eyton). 



Picolaptes notatus Eyton, Contr. Orn. 1852. p. 26 (Rio Negro, apud. 



Berl. & Hart.). 

 Dendrornis obsoleta notata Beriepsch & Hartert, p. 64. 



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 Beriepsch 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 the mouth of the Malo River.
