AMETHYSTINE HUMMING-BIRD.

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 
EUBY-THEOATED HUMMING-BIED.

point out its marking in the different liveries.
