These birds differ so conspicuously from specimens from Cayenne and British 

 Gtiiana by their paler coloration, that it is necessary to bestow a new name on the 

 Orinoco and ( 'anra river race. The dimensions are the same. Sjiecimens in Mas. 

 Berlepsch from Yquitos (E. Pern) and Eastern Ecuador agree perfectly with the 

 Orinoco birds.

 dark grey ; feet grey ; maxilla black, mandible light grey at base, grey at tip." 



The adult males have a large portion of the interscapular region deep black. 

 The Snapnre specimens agree with others from Bogota collections. The less black 

 interscapulinm is ajiparcntly a sign of iuimatnrity. The authors say in their 

 diagnosis " interscapulio non uigro."
