peculiar actions and habits ; an account of which would doubtless prove highly interesting, as they probably 

 differ as much from those of the members of the group as the bird does in its form and colouring. 



As is very commonly the case among the Trochilidse, the sexes present a marked difference in appearance, 

 the beautiful crest which adorns the male being entirely wanting in the opposite sex. 



Sir Robert Schomburgk found this bird in Barbadoes, and specimens collected by him are contained 

 in the Collection at the British Museum. As will be seen on reference to his " History of Barbadoes," 

 it is the only Humming-bird observed by him in that island. 



The male has the forehead and crown rich golden-green, blending into the rich deep blue of the elongated 

 crest-feathers ; sides and back of the head, upper surface of the body, wing- and tail-coverts dark grass- 

 green ; wings purplish-brown; two centre tail-feathers dark purplish-green, the remainder purplish-black; 

 under surface dull black, with a wash of grey on the throat ; bill and feet blackish-brown. 



The female has the head, all the upper surface, wing- and tail-coverts bronzy-green ; wings purplish- 

 brown ; central tail-feathers dark bronzy-green, the remainder purplish-black, the two outer on each side 

 slightly tipped with grey ; under surface dark smoky-grey, somewhat lighter on the throat. 



The accompanying Plate represents two males and a female, of the size of life. The plant is the CaUiandra 

 brevipes*
