FEMALE CAPE MAY WARBLER.

the same length as the fourth ; the second and third are long- 
est, and but little longer than the fourth. The tail is slightly 
emarginated, the feathers being dusky, edged with bright olive 
green on the exterior side, and with white on the interior ; the 
two or three exterior feathers on each side have a pure white 
spot on their inner webs near the tip. 
The female Cape May warbler may be very easily mistaken 
for an imperfect Sylvia coronata, of which four or five nominal 
species have already been made. The striking resemblance it 
bears to the young, and to the autumnal condition of the plu- 
mage in that species, requires a few comparative observations 
to prevent their being confounded together. The present bird 
is smaller than the coronata, with a more slender, and rather 
more elongated bill; it is altogether destitute of the yellow 
spot on the head, as well as of the yellow on the rump, which 
is a striking character of the coronata in all its states, and gives 
rise to the English name adopted by Wilson. 
The colour of the outer edging of the wing and tail feathers 
is a very good distinctive mark ; in the maritima it is olive 
green, whilst in the coronata it is white. The white spot on 
the inner webs of the exterior tail feathers, is also four times 
larger in the coronata than in the maritima.
