This genus comprises, according to my views, two species, the 

 present and the one following. The one now under consideration 

 is among the most beautiful of all Humming-birds ; and although 

 it was formerly common in collections, having been received 

 chiefly from Martinique by the French naturalists, it has become 

 of late years rather scarce. There does not seem to be any 

 difficulty in the synonymy, the species being too conspicuous and 

 well marked to be easily mistaken for any other.

E. holosericeus has been known for many years to ornitho- 

 logists ; and there are few collections that do not contain 

 numerous examples. Mr. Gould, in his well-known work on this 

 family, has named a bird supposed to come from the island of 

 Nevis E. chlorolcemus. With every desire to perceive any spe- 

 cific diff'erence it might exhibit, and although I have examined 

 carefully, by the kindness of Mr. Gould, the specimens in his
