The series of specimens examined, including the type of Psitta- 

 cula cyanochlora, Natt.*, shows a great amount of individual 

 variation, probably according to age. In one specimen from 

 Colombia the rump is shaded with blue. The foremost greater 

 upper wing-coverts, which are generally green, show in some speci- 

 mens, and particularly in one old male from Villadupar, a fine 

 cobalt-blue tinge ; the deep blue colour on the under wing-coverts, 

 which in the type of P. cyanochlora leaves only the feathers on the 

 margin of the wing green or bluish green, is similarly diffused 

 in the specimen from Villadupar, already mentioned, while in the 

 majority of the specimens it is confined to the innermost under 

 wing-coverts. 



I have not seen specimens from Guiana, which require com- 

 parison.
