certainly referable to praticola on the basis of size (wings 98.5 and 
99 mm., respectively), which, according to Hellmayr (Catalogue of 
the birds of the Americas, pt. 10, 1937, 217) is the only “absolutely 
constant character separating this form... .” They differ from 
the only other example of the race seen, a female from Forto do Rio 
Branco, Brazil, January or February (Pelzeln), in having the two 
dark coronal stripes and the postocular stripe much darker, fuscous 
black, as opposed to ferruginous streaked with black in the female. 
The latter specimen is in very worn and faded plumage generally.

The immature bird from San Antonio is tentatively placed in this 
form, but it is not certainly indentifiable. The adult males agree 
with a series of specimens of brevirostris from ‘Bogota’ and eastern 
Ecuador. Judged by Hellmayr’s account (Catalogue of the birds of 
the Americas, pt. 9, 1936, pp. 24-25) they appear to be the first 
actual records of the race from Brazil, although the range as stated 
there implies that extreme western Amazonia belongs in the range of 
this form. The distribution is as follows—tropical and subtropical 
zones of eastern Colombia, eastern Ecuador, and eastern Peru, to 
southern Venezuela and to British Guiana. The nominate form, 
which is slightly smaller, and, in the males, has the yellow cap paler, 
less orange, is more eastern and southern in its range, leaving quite a 
gap from which apparently no specimens have been collected. The 
two Rio Cauabury birds help a little to reduce this gap from the 
north. 
The immature male from Puerto Ayacucho resembles the female 
plumage but is much yellower below and darker above.
