Descriptions of Three New Species of Humming-hirds. lOY 



brown and white. Tail mncli of the color of the upper part 

 of back, but more mottled with grey. Entire under parts 

 dark brownish-red, each feather having large blotches of white 

 edged with black, small on the breast, but becoming larger on 

 the abdomen. Bill black; feet and tarsi brownish-black. 

 Length 7|- in. ; wing 4i ; tail 2f ; tarsus 1^. 



Hob. — Honduras. 



Remarks. — ^This new species of Eupsychortyx is allied to 

 E. Sonninii of Temm., but differs in the absence of buff on the 

 sides of the head, and in having the white blotches of the lower 

 parts extending nearly to the throat, and not interrupted by a 

 band of reddish. It can, however, easily be distinguished from 

 any known species of Eupsychortyx in having two distinct 

 white stripes on each side of the head, which give to it the 

 appearance of wearing a bridle. The specimen described was 

 obtained in Honduras by Mr. Amory Edwards, a gentleman 

 much attached to Natural History, and brought by him, among 

 some birds which he had collected during a short sojourn in 

 that country. 



Of the habits of JS. leucqfrenatus I know nothing, but sup- 

 pose they do not differ from those of the other species of this 

 genus.
