A single specimen (apparently an adult male) of this bird graces the collection in the Museum of the Jardin 

 des Plantes, at Paris. This individual was, I believe, brought to Europe by M. D'Orbigny, and was 

 procured either in Peru or Bolivia. The Eriocnemis D* Orbignyi differs from all the other species of the 

 genus I have yet seen, in the possession of a blue frontlet ; in size it is very similar to E. vestita, from 

 which, however, as well as from all the others, it differs in several well-marked specific particulars. 



The unique specimen contained in the Paris Museum serves to show how little acquainted we are with 

 the Humming-Birds of the countries to the southward of Ecuador. That both Peru and Bolivia possess 

 many species as yet unknown, there seems to be but little doubt. 



The following is a description of this bird taken from the Paris specimen : — 



Forehead violet blue ; all the upper surface uniform bronzy grass-green ; throat and under surface 

 glittering golden green, inclining to blue on the centre of the throat and chest; tail steel or bluish black. 

 The figures are of the size of life. The plant is the Hoivardia Caracasemis.
