ITah. Mexico (Oaxaca). 



Ilalc. Upper surface bronzy-green, brown on top of the liead, under parts dark 

 grayish-brown. Ear-cover's bhickish-brown. Vent white. Tail bronzy olive-green. 

 Wings pale purplish-brown. A white spot behind the eye. Bill flesh-color, tip 

 black. Feet black. Total length, 4| in. Wing, 2| in. Tail, 1| in. Culmen, | in. 



Female. Differs in being lighter beneath, and in having a subterminal blackish- 

 brown band on the lateral rectrices, which are also tipped with grayish-white. 

 Dimensions the same as the male. 



One of the most extensive of the genera of Humming-birds is now reached : 

 viz. PhvETUorxis, comprising no less tlian twen'y-two species. The majority are 

 plainly attired, without any metallic coloring, and ajl are chiefly remarkable for 

 their peculiarly shaped tails, the middle feathers of which extend beyond the 

 rest, and are always longest in the females. I have included in this genus those 

 birds usually separated under the term Pygmornis, as I do not find that they really 

 possess any characters to entitle them to a distinct generic rank, and it is impossible 

 to ascertain where PflyETHORMis ends and Pygmornis begins. All the species are 

 closely related and form one natural group.
