and the whole of the upper surface green ; the two middle feathers of the tail are green with 
slight bronzy reflexions, the two next on each side are black, with their extreme outer 
edges of the same colour as the two middle ones, the tips of the whole six being black ; the 
three outer ones on each side are regularly barred with black and white on their outer 
edges and slightly so on their inner ones, while their centres are black and their tips 
white ; centre of the wings beautifully freckled with grey on a black ground ; primaries 
black, with their extreme outer edges white ; under surface fine orange, separated from the 
black of the throat by an obscure half band of white ; feet brown. 
Female. Head, throat, upper surface, and six middle tail-feathers brown, the latter slightly 
tipped with black; the remaining tail-feathers as in the male, but not so regularly barred ; 
the centre of the wings freckled with brown on a black ground ; the primaries black

Figures of both sexes of this species have graced the pages of many ornithological publications, in almost 
every one of which it has been subjected to a different name. The female, from the dullness of her colouring 
when compared with her gaily-attired mate, has, in most instances, been characterized as a distinct species ; 
and had not the illustrations of this bird been tolerably good, it would have been unsafe to have quoted so 
many synonyms as are recorded above. 
I am induced to believe that the Yellow-bellied Green Cuckoo of Edwards is identical with the male, while 
the female is represented by Buffon in his Planches Enluminees under the title of Courucou a queue rousse ; 
it is also the Rufous Curucui of Dr. Latham. 
In the splendid work of LeVaillant will be found figures of both the sexes under the name of Courucou 
aranga, which name has been followed by Vieillot, who has figured the male in the second edition of his Nouveau 
Dictionnaire d’Histoire Naturelle, under the scientific name of Trogon atricollis. Although this latter name 
has not, perhaps, a strict claim to priority, yet in a case like the present, where the female has been described 
as a distinct bird from the male, and as it appears doubtful whether the latter is identical wdth the old Trogon 
viridis, I have thought it best to follow Vieillot in giving to this species the specific title which he has applied 
to it.
