Remark. ‘This species is yery nearly allied to the Zrochilus 
geofroyt of authors, which with the present bird I have deemed it 
requisite to raise to the rank of a genus.

ERIOPUS LUGENS, Govnp. 
Crown of the head, back, shoulders, and upper tail-coverts, 
bronzy green, slightly tinged on the latter part with rufous ; throat, 
abdomen, and under tail-coyerts, hoary black, with a tinge of green

of the throat and chest; tail bluish-black; wings purplish-black ; 
lengthened feathers, forming a ruff round the thighs, white; front

Habitat. The neighbourhood of Quito, in Ecuador. 
Remark. ‘This species which is about the same size but some- 
what more robust than Z. awrelic, would appear, from its sombre 
colouring and thick but lax plumage, to be a frequenter of the. 
colder regions of the country it inhabits.
