2. Description of a New Genus and Species of the Family 
Trochilide. By Joun Gouxp, F.R.S, &e. 
Genus OREONYMPHA. 
Gen. Char.—Bill longer than the head, stout, and with a some- 
what downward curvature; wings large and sickle-shaped; tail 
ample and forked; tarsi clothed nearly to the toes, which are of 
moderate size ; the hinder toe and nail rather shorter than the middle 
toe and nail. ) 
Notwithstanding the length and stoutness of the bill, I consider 
this form to be nearly allied both to Oxypogon and Ramphomicron. 
It has the same kind of brilliant gular streak, a similar laxity of 
plumage, and soft flexible tail-feathers. 
OREONYMPHA NOBILIS. 
Bill and legs black ; crown blue, with a streak of black down the 
centre; on the throat a lengthened streak of brilliant feathers, of 
which those nearest the bill are green, those which succeed are red-
