Tuts species is unknown to me ; but the type is in Mr. Elliot’s collection. It is supposed to have come from
Ecuador ; but Mr. Elliot does not state from whom he re

the genus in which the downy puffs on the tarsi are white, and it differs from al

| the allied species in having
the under tail-coverts purplish black instead of grey, green

, or shining blue.
Mr. Elliot writes :—<“ Among the many groups that comprise the great family of the Trochilide, there
are few more strongly characterized than that of Eriocnemis, from the fact that all its members are possessed
white, black, brown, or brown and white, which cover the
tarsi, and from which the species have obtained the trivial name of Puff-leg.’
“Four specimens, precisely alike, were, as I was informed, contained in the

from which my example was taken ; and although no locality was give

of very conspicuous tufts of various colours, viz.

small collection of birds
n, it is supposed that Ecuador is the
habitat of the species. I propose to call it, from its sombre plumage, Eriocnemis dyselius.”

The following is a copy of Mr. Elliot’s original description :—

“Head, and entire upper parts, black with a parplish gloss ; upper tail-coverts having a very dark
greenish gloss ; throat and underparts black, bat not of so deep a shade as the upper parts, purplish on the
abdomen ; wings purplish black ; tarsi thickly covered with pure white downy feathers ; under tail-coverts
purplish black; tail rather deeply forked, steel-blue, with purple reflections ; the bill is perfectly straight
and rather slender. Total length 4 inches, wing 234, tail 14, bill 2.”
