3g SYNOPSIS OF THE HUMMING-BIRDS. 



111. Zool. The second of these is the type of Topaza, Gray, the third under its 

 proper name of Fuscus, Vieill., is the type of Florisuga, Bon., leaving the T. mango, 

 Linn. ( = jiorpJiyrurvs, Anct.), as the type of Lampornis, Swains. 



The genus Smaragdites, Boie (1. c), is a composite one. The first species cited 

 by him is Trocliilus virkUssimus, but as no author's name is given, it is impossible 

 to say what species is intended. The next is T. aurulenius, Vieill. (^ T. domini- 

 cus, Linn.), and this I have adopted as the type of his genus. 



Key to the species. 



A. Throat black. 



a. Under surface black. 



a'. The green flanks separated from the black abdomen by a line

 are moderate in size, and their metallic colors are chiefly confined to the throat 

 and breast.
