This Hiimming-bird is easily recognizable from the other species of Oreopyra by its metallic purple throat, 

 the other two species having white throats. 



It w^as originally described by Mr. Salvin from specimens procured by Enrique Arce on the Volcan de 

 Cartago in Costa Rica, and it has since been obtained in the State of Panama. 



The following is a translation of Mr. Salvin's original description : — 



Back greenish ; head with the breast bluish green, very brilliant, the latter being more distinctly green ; 

 entire throat and cbin glittering violet-red ; ear-coverts and sides of nape black ; a long postocular streak 

 of white, extending as far as the nape; belly dull ashy, sligbtly washed with green; vent uniform, the 

 feathers margined with white; wings purplish black, the wing-coverts green ; tail steel-blue. Total length 

 4 inches, wing 2'6, tail 1*4, longest tail-feathers TS, bill from gape 1. 



Two males and a female, of the natural size, are depicted in the Plate, drawn from typical specimens lent 



to us by Messrs. Salvin and Godman.
