Tue present species was described by Mr. D. G. Elliot from a specime

n procured by M. Eugéne Rébouch,
a young collector for the well-known naturalist Mr. A. Boucard.

The type specimen, which still remains
unique in Mr. Elliot’s collection, was obtained at Putla, in Western Mexico, on the Pacific slope.

There are three closely allied species in the genus Eupherusa, the differences between which are set forth
by Mr. Elliot in his ‘Synopsis.’ In £. poliocerca the two central tail-feathers are light bronze-green, the
lateral ones white margined with purplish grey. In the second species, . ewimia, the tail is dark greenish
bronze, the two outermost feathers with the basal two thirds of the inner webs white; while the third,
E. egregia, has the four central rectrices dark greenish bronze, the remainder white margined with black.

’ says Mr. Elliot, “is most nearly allied to Eupherusa egregia, but can at once be distin-
guished from it, as well as all the other members of the genus, by its tail. In /. egregia the four centre

“This species,’

tail-feathers are black, and the remainder are black at the tips; in the present species only the two median
feathers are bronzy, all the remainder being as described above. This bird was obtained in a small collection
of birds procured at Putla, in the western part of Mexico. This is the third species now known of the genus
Eupherusa, which was for a long time only represented by Z. eaimia. The species are as follows:—E. evimia
from Guatemala, /. egregia from Veragua, L. poliocerca from Putla, in Western Mexico. Two species named
respectively EL. cupreiceps and LE. nigriventris have been allotted to this genus; but I think that they will
hereafter be assigned to another genus, Thaumatias, to which they seem more naturally to belong.”

“ Adult male——Top of head and upper surface bronzy green ; entire underparts brilliant grass-green.

Wings purple; secondaries chestnut-red. Under tail-coverts pure white. Two central tail-feathers light

I have in the present case quoted largely from my friend Mr. Elliot’s work; but it was unavoidable, as

there is absolutely nothing known of the species beyond the account which
: size, drawn from the typical specimens lent to me

he has given of it.
