 There is no difference whatever in colour or size between 

 specimens from Bahia, Pernambuco, Mattogrosso, Rio de 

 Janeiro, Manaqueri, Borba, and Santa Cruz, E. Peru. 



Two ^ ad. from the vicinity of Para" have the forehead 

 and anterior portion of the crown rather lighter, more orange- 

 red, while in all the other specimens examined these parts 

 are of exactly the same deep crimson as the occiput. They 

 may represent a different race, but I should like to see more 

 specimens before separating it.
