Trochilidees, p. 85, pis. xxriii. and xxix. 
There are three Humming-birds, which, though 
not coming in the same group, we shall now introduce 
together, from a confusion seeming to have arisen in 
the discrimination of the species. They are gene- 
rally known under the name of the “ Amethysts,” 
and Lesson proposes to distinguish them by the titles 
“ L’Amethyste, Le petit Amethyste ou L’Amethys- 
toide, et L’Amethyste a queue egale.” The last, 
the subject of our plate, we shall first describe. 
The length of this species is about two inches 
and a half : the head, neck, back, rump, and upper 
tail-coverts, are golden-green ; two narrow lines 
of white spring from each corner of the mouth : the 
fore-part of the neck, and running upon the breast, is 
covered with a patch of scaly feathers, of a rich 
amethystine purple, changing to red with the posi- 
tion : this patch is surrounded with a broad band of 
greyish- white, which extends upwards upon the sides
