Habitat. — Dominica (West Indies) not Brazil. 



Male. — Entire head and throat deep blue, slightly metallic. 

 Upperside dark shining green. Tail steel-blue. Tail-coverts 

 greenish-blue. Underside metallic grass-green, golden on 

 sides of breast and flanks. Wings dark purplish-brown. 

 Maxilla black. Mandible flesh colour tipped with black. 



Total length, 3fin. Wing, 2§. Tail, if. Culmen, f. 



Female. — Upperside bronzy-green. Uppertail-coverts 

 bluish-green. Underside dull white spangled, with green on 

 the sides of breast and flanks. Outer-tail feathers tipped 

 white, rest of tail-feathers green, broadly marked with blue on 

 the terminal part. 



It is a rare species, and it is only since a short time that we 

 know with certainty that this species is not Brazilian, as all 

 former authors have constantly told us, but a native of 

 Dominica, West Indies. I think Mr. Ober, who has collected 

 largely in the West Indies, is the naturalist to whom we are 

 indebted for the exact habitat of this species.
