Habitat. — Guiana. 



Male. — Upperside shining grass-green. Median rectrices 

 dark bronze-green, next one bronze for about half its length, 

 then bluish-black and slightly margined with white at tips, 

 the others bronze at base, then bluish-black to half their 

 length, the rest pure white. Underside dark ashy-gray, 

 sparingly washed with green on sides of neck, breast and 

 flanks. Wings shining purplish-brown. Maxilla black. 

 Mandible flesh-colour with black tip. 



Total length, 5|in. Wing, 3^. Tail, 2\. Culmen, i. 



Female. — Smaller and slightly paler in colouration, other- 

 wise exactly like the male. Lateral rectrices with scarcely 

 any bronze at base, but bluish-black for half their length, and 

 the rest white. Only very adult males have the shafts of the 

 primaries broad and flat on their basal half. I have some 

 very fine males where this peculiarity is scarcely visible. 



My fine series of this species were collected by Mr. H. 

 Whitely, in British Guiana.

I cannot see any differences between this species and the 

 preceding one, and I am of the same opinion as Messrs. 

 Elliot and Mulsant that they all belong to one species.
