Hi n I (/r.— Mexico (including Yucatan) and Guatemala; Guiana and 

 upper Amazon Valley. (Four species.) 



The three Mexican species of this beautiful genus include two types, 

 which differ slightly in structural details and considerably in pattern 

 of coloration; one type (represented by G. venustut^ and G.francescm) 

 having the tail longer than the wing, the thi'oat and a considerable 

 part of the lateral rectrices white, and the auricular region black; the 

 other (represented l)y G. sallmi) having the tail shorter than the wing, 

 the throat and auricular region gray, and the lateral rectrices wholly 

 black. The single known South American species {G. pelzelni) com- 

 bines the white throat and black auriculars of the first-mentioned 

 group with the shorter tail and wholly black lateral rectrices of the 

 last mentioned.
