Ne = APR NPN AP ENE EN SPN ERIOCNEMIS SIMPLEX, Gould. Olive-coloured Puffle. Eriopus simplex, Gould in Proe. of Zool. Soc., 1849 Deon 9 Tux single specimen of this bird forming part of the collection of Edward Wilson, Esq., is the only one that has yet been sent to Europe. It was received direct from Santa Fé de Bogota, accompanied by other new and Pare species, which induces a belief that it had been procured in some district not previously visited by collectors. Mr. Wilson, with his usual liberality, kindly lent me the specimen for the purpose of describing and figuring it, if requisite. During the three years it has been in my possession, I have frequently Peomined and carefully compared it with Erzocnemis cupreiventris, under the impression that it might possibly be merely a singular variety of that bird, but I have always returned to my original opinion, that it is a Aietinet species, and have therefore figured it as such on the accompanying Plate. The colouring of the entire body is a nearly uniform dark olive-green, with a rufous tinge on the upper surface ; the crown of the head and back of the neck tinted vi pomples tne rump antl upper iy coverts a very little brighter than the back; on the throat, a patch of scale-like feathers of a more glossy green than the other part of the under surface; wings purplish pone tail black with purplish a anya and tarsi thickly clothed with snow-white plumes, presenting a strong contrast to the dark colourmg of the body; under tail-coverts dull bluish purple ; bill ame feet black. oe The figures are of the natural size; the Cactus is a species common on the Columbian Andes.
