In attempting to investigate the little gree ing-Bir . Onn

2 | a g green Humming-Birds, the ornithologist enters upon a task of no
ordinary difficulty. Many have been the days I have spent in endeavouring to correctly Separate into species
aurigaster, and angustipennis, with, in every inst
but a satisfactory result ; and, had I not had access to the typic

the birds known by the name of chrysooasser :
kK ) ysogaster, ance, anything

al specimens to which these terms had been

0 have achieved what I have done in the present work. Of one
thing I am certain, namely, that the angustipennis of Fraser and the e

applied, it would have been impossible t

hrysogaster of M. Bourcier are one
or I have the types of both now before me, and they do not differ in the slightest degree.
M. Bourcier, I believe, considered his chrysogzaster to differ

and the same bird: f

from angustipennis in having a brilliant crown ;
but his type-specimen, with the name of chrysogaster written by his own hand, is destitute of brilliancy on
that part; I am therefore induced to consider that both names have reference to the same species, and
thus the law of priority compels me to adopt that of angustipennis, and sink chrysogaster to the rank of a
synonym. As to the aurigaster, 1am still in doubt. We really want better information respecting the
little green Humming-Birds, and a larger number of specimens than we now possess, before the various
species can be determined with accuracy ; at present, we do not even know with certainty the female of
the very common bird here represented ; in all probability she will have all the under surface grey washed
with green on the flanks, and a tail, unlike that of the male, with the two centre feathers green, the two
next green at the base, then black, and white at the tip, while the two outer ones will probably be green at
the base, succeeded by three nearly equal bands of grey, black, and greyish white. I have a Sa
from Panama which Secpors to this description, and which I think may be the female of the present species ;

est such should not be the case.
