In the American ^Museum collection are specimens from points 

 on the Caura River, which agree exactly with Ciudad Bolivar and 

 Caicara specimens. 



Hapalocercus meloryphus (VVied). 

 Euscarthmus meloryphus Wied. Beitr. Naturg. Bras. III. 1831. p. 947. 

 Hapalocercus meloryphus Berlepsch & Hartert, p. 40. 



Rare. Only once met with by the writer, an adult female having 

 been collected at Ciudad Bolivar April 8, 1905. 



Eye seal brown ; bill above black, below pale ; feet grey. 



The specimen secured was discovered perched low down on the 

 limb of a tree at the edge of a small clump of trees and bushes on 

 the savanna. In actions the bird was decidedly flycatcher-like ; but 

 the scutellation of the tarsus^ is very like that of Formiciz'ora and I 

 am following Mr. Ridgway- in including it with the Formicarlidae. 



Berlepsch and Hartert record a single specimen collected by 

 Klages that was taken at Ciudad Bolivar. 



The outer and middle toes are united at the base for the length 

 of the basal phalanx of the outer toe, and about one-half the length 

 of the basal phalanx of the middle toe. Outer toe with claw slightly 

 longer than the middle toe without claw ; without claw reaching to about 

 the middle of the stibterminal phalanx of the middle toe.

Not observed on the Orinoco, but recorded from Suapure on the 

 Caura River. 



Cercomacra cinerascens (Sclater). 



Formicivora cinerascens Sclater, P. Z. S. 1857 p. 131 (Rio Napo). 



Cercomacra napensis Scl., P. Z. S.. 1868. p. 572 (Rio' Napo) ; Berlepsch 

 & Hartert, p. 75. 



Cercomacra cinerascens, Hellmayr Novit. Zool. XII: 1905: 287 (habi- 

 tat and crit.). 



•The following observations were made as a result of an examination of a fresh tarsus; the icrotarsium 

 covers somewhat more than the anterior half of the tarsus. On the plantar tarsi is a double row of elongated 

 irregularly quadrate scutella extending from the heel to the toes; but from the point of the heel for a short 

 distance down the double series is separated by a median row of small scutella. There is also a narrow 

 non scutellate area along the inside face between the edges of the acrotarsium and the scutella covering 

 the planta and a similar area on the outside at the upper end.
