Species of the Genus Pipra. 1 1 



There is very little variation in a large series of males 

 from different localities. Some have the red tips of the 

 breast-feathers and the black apical margins of the under- 

 tail-coverts rather wider than others, but this does not depend 

 on locality. The specimens from Chuchurras, Centr. Peru, 

 shew, perhaps, the throat of a purer yellow ; they are, how- 

 ever, exactly matched by one male from Fazenda Cayoa in 

 S. Paulo. As will be seen from the measurements given 

 below, two males from North Bolivia (topotypical) are rather 

 larger, but this is not likely to be a constant character, since 

 the skins from Central Peru are fully as short-winged as 



those from Brazil.

The species has been recorded from the B-io Tocantins, 

 near Para, by Messrs. Sclater and Salvin. Their specimens 

 are not in the British Museum, so that I could not ascertain 

 myself whether they are really identical with the form in- 

 habiting Western Brazil and Bolivia.
