pear, and the tail is red. The young of this species, 
according to Lesson, would therefore appear to re- 
quire the fourth summer to perfect their plumage, 
to attain the full perfection of all their organs. 
The Ruby-throated Humming-Bird is a native of 
the Brazils. Species brought from that country by 
MM. Quoy and Gaimard, decided the before unde- 
termined locality of the species. 
WEDGE-TAILED AMETHYSTINE HUMMING- 
BIRD.

Trochilidees, pis. liii. and liv. 
This bird differs from those arranged under the 
title of amethysts, hy the form of the tail, which is 
strongly wedge-shaped at the tip. It would seem, 
as far as we can judge from the representation of 
Lesson, to range nearer the Nootka Humming-Bird. 
It is a native of Mexico ; its length is about three 
inches. The upper parts of the plumage are of a 
clear and shining green, and a laige patch of bright 
amethystine red covers the breast, and is bordered 
beneath by a band of pure white ; the belly and vent 
ai-e white, dashed with reddish on the flanks. The 
tail, of the form we have mentioned, has the centre 
feathers of a clear green, the lateral ones brown.
