Boié, one of the most philosophical of modern ornithologists, proposed the generic term of Hylocharis for the Trochilus sapphirinus of Gmelin; and I have much pleasure in adopting this name, as well as several others proposed by him. The genus Hyrocharis is composed of three species, all of which are natives of Brazil, to which country they are mainly confined. They are all very pretty, if not showy, species; and one of them is among the oldest-known members of the entire family, as will be seen on reference to the synonyms; brilliant blue is the prevailing colour of the males, while the opposite sex is but plainly attired.
