vermilion, tip apple-green^' (Brabourne). Tiiese specimens 

 were collected and presented to the British Museum by the 

 late Lord Brabourne. 



Having examined a large series of this species in the 

 British Museum from various localities in South America, I 

 find that the individuals mentioned above are rather smaller 

 in wing-measurement than those from the south and east, 

 I may mention, however, that they are chiefly immature 

 birds, v.'hich may account for it. I notice, too, that the birds 

 from southern Peru, Lake Titicaca, and northern Chile 

 have a larger average wing-measurement than those from 

 other parts of the continent. These no doubt represent 

 the form described by Alien under the name C. garmani 

 {rfr. Bull. Mus. Comp. Zool. Cambridge, Mass., iii. 187G, 

 p. 357). It is unfortunate that in this fairly large series 

 there are no specimens from Sao Paulo, the type-locality, 

 with which comparisons could be made.
