Male. — Upperside shining dark green, coppery on rump. 

 Uppertail-coverts glittering green with bluish reflections. 

 Tail dark shining blue. Throat metallic grass-green, yellowish- 

 golden in some specimens, especially in those from Martinica. 

 In the middle of the breast, bordering, the green, is a small 

 patch of bright blue feathers. Abdomen black. Flanks 

 bronzy-green. Vent and a spot on each side of flanks white, 

 Undertail-coverts glittering blue, edged with green. Wings 

 purplish-brown. Bill black.

Female. — Has less blue on the breast, is not quite so bright 

 in colouration, and has the bill longer. This species is rather 

 abundant in all the Lesser Antilles, and I think that when full, 

 series of each island will be sent to Europe, it is possible that 

 it will be necessary to separate them in two or three species.
