These specimens, as well as several others examined ia the Vienua Museum, 

 correspond exactly to Temmiuck's original description. The upper parts are bluish 

 slate-grey, waved with black cross-lines and bars, broader on the rump and upper 

 tail-coverts ; on each side of the occiput aud hiadneck a distinct longitudinal stripe, 

 banded black and white ; throat and cheeks white, dotted and freckled with black ; 

 foreneck slate-grey, breast and alidomen paler, more ashy, waved aud banded with 

 blackish ; under tail-coverts deep ochraceous cinnamon, mottled with black. 

 Whether the examples from Venezuela (San Esteban) and Bogota described by 

 Salvadori {I.e.) as having the " upper parts greyish olive," and the under tail- 

 coverts " grey, rufescent along the middle," belong to the same species appears 

 to be open to doubt.

These birds are typical of serratus, agreeing with otliers from the Rio Negro 

 and Mattogrosso : forehead, pilenra, and ear-coverts clear cinuamon-rnfous ; no 

 trace of an occipital crest ; middle of the abdomen plain white, without dusky 

 cross-lines, etc. 



T. .s. serratus ranges from the upper Rio Negro (Marabitanas) and the C!aura 

 Valley, Eastern Venezuela, to the Madeira and Guapor6 Rivers. It extends 

 perhaps to Central Peru (Huanuco), though specimens from this country are 

 slightly different. (Cf. Hellmayr, I.e. p. 719.)

 Eastern Pern.
