' BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 455 
describe the Ecuadorean bird. The more northern birds are slightly 
smaller than those from Bolivia.’”’ From this it would seem that Rio 
Negro and Venezuelan birds (hyposticta) agree with Bolivian gutturata 
in color, and not with Ecuadorean (peruviana?) specimens. Carriker 
found topotypical perumana to be darker than gutturata above, 
especially on the nape and upper back, the nape brownish slate (olive- 
brown in Puno “gutturata’’), the underparts paler, more whitish, 
less ochraceous, in all of which characters the present series would be 
gutturata, yet he considered them as peruviana. This confusion 
suggests that peruviana may either be less well defined than Carriker 
believed or that it must be regarded as a purely Peruvian-Ecuadorian 
race. The latter seems unlikely as the birds from eastern Ecuador 
might then be expected to agree with the Bolivian-Brazilian-Vene- 
zuelan interior form and not with that of central northern Peru. 
Until further material becomes available it seems wisest to recognize 
no races of this spinetail. This, in effect, is a corroboration of Hell- 
mayr’s earlier judgment (Catalogue of the birds of the Americas, 
pt. 4, 1925, p. 131). 
The two immature birds are slightly duskier below than the adults.
