‘‘ Adult female :—Upper parts less lustrous than in the male, the feathers margined more or less with
rufous grey ; wings as in the male; tail with the middle feathers brilliant green, the rest cinnamon, with a
purplish-black band running from the outer feather obliquely downward and inward to the tips of the fourth
on each side, forming a broadly-shaped mark ; between the black band and the cinnamon there is a spot of
bright green, most conspicuous in the feather next the central ones, and growing gradually indistinct towards
the outer ones; throat pale rufous white, the centre of the feathers darkest, and on the sides and posteriorly
a little green; abdomen entirely rufous ; legs and crissum pale rufous. The dimensions do not differ from
those of the male.

‘Young male in winter :—Upper parts intermediate in brightness between the male and female ;
white, with a few feathers beginning to show the violet ; tail as in the male.

‘‘ All the males procured by me, four in number, had but eight tail-feathers ; while all the females, three

in number, had ten. It can hardly be supposed that in four specimens, the same two feathers, and but two,

throat

should have been lost from every specimen. In form the tail-feathers are rather narrow, and the inner
webs of the two outer slightly falciform or emarginated. The two outer feathers are slightly shorter than
the next, which are the longest; the next two again are rather shorter, and the central ones considerably
shorter. The feathers composing the tail of the female are broader than those of the male; the third
from the outside is the longest ; the first, second, and central one as in the male ; and the fourth slightly
shorter than the third.”

Dr. Bryant has deceived himself as to the number of the tail-feathers in the male : all Humming-Birds
have ten ; but in some instances the middle feathers aré so short as to be entirely hidden by the coverts, and
this is precisely the case in the male of Calothorax Evelyne.
