Female. — Upperside bronzy-green, greenish on upper tail- 

 coverts. Underside «ray, tinged with bronze feathers on sides 

 of breast and flanks. Middle pair of rectrices bronze-green, 

 the next three green at base, then steel-blue with white tips,

 minal bluish-black bar, and white tips. Ear-coverts black. A

This pretty species is common in Mexico. I have killed 

 many specimens at Tospam, near Cordoba. It was discovered 

 by Delattre, and dedicated by Lesson to Mr. Canivet, a French 

 naturalist.

The only difference between this species and the preceding 

 one, consists in the colour of the underside, which is metallic 

 emerald-green on the throat and breast, and the colour of its 

 rectrices which are steel-blue with a narrow bronze tip on 

 central feathers, the tail is also shorter.

 alike.
