SYNOPSIS OF THE TROCHILID^. 



throat and breast with an amethystine gorget, sue- 

 ceeded by a band of white ; lower parts cinnamon- 

 red ; tail equal, golden-green, black at the tips, ex- 

 cept the two outside feathers, which are tipped with 

 white. Inhabits Brazil. 



We have placed this provisionally in Cynanthus ; the bird 

 seems only well known in its young state, when the tail is 

 square. It is introduced upon the authority of Lesson.

 Above golden-green ; throat with a gorget of bright 

 carmine ; feathers rounded and capable of expanding ; 

 under parts pure white, greenish upon the flanks ; 

 tail slightly graduated, centre feathers golden green, 

 others steel-blue, margined with chestnut. Inhabits 

 Mexico. 



Swainson appears to make the form of the tail a principal cha- 



racter in his division Cynanthus. We have introduced T. 



tricolor, therefore, with a mark of doubt, from the diflerence 



in form. In other respects it is closely allied.
