AMETHYSTINE HUMMING-BIRD. 9] 



exhibiting no appearance of a scaly form, and a few 

 violet feathers are represented appearing. The plu- 

 mage is a little duller in shade, and the tail has not 

 reached the greatest development of the fork ; but 

 the white band is conspicuous, running over upon 

 the back. 



In the very young state, the tail is like that of 

 those allied birds just described, rounded, with pale 

 tips, the colour dark. The upper parts are a pale 

 golden green. The patch on the throat is pure white, 

 running into the crescent-shaped band, and the vent 

 and belly are reddish-brown. 



This species is a native of the north parts of Gui- 

 ana and Brazil, and, though long known, is by no 

 means common in modern collections. The next 

 bird we shall mention as allied to this is the 



RUBY-THROATED HUMMING-BIRD.

THIS very splendid species has been described 

 by authors under various names, in the states from 

 young to adult plumage. We shall endeavour to 

 point out its marking in the different liveries.
