190 FEMALE CAPE MAY WARBLER. 
small pale spots; the upper parts of the neck and of the 
body are olive cinereous, tinged with more cinereous on the 
neck, and with yellow olive on the rump. The chin is 
whitish; the throat, breast, and flanks are whitish, slightly 
tinged with yellowish, each feather having a blackish spot on 
the middle; the belly is immaculate; the vent and inferior 
tail-coverts are shaded in the middle of each feather with 
dusky. The smaller wing-coverts are dull olive green, 
blackish in the centre; the middling wing-coverts are black, 
margined exteriorly, and tipped with pure white; the greater 
wing-coverts are blackish, margined with olive white; the 
primaries are dusky, finely edged with bright olive green on 
the exterior web, obsolete on that of the first primary, which 
is of the same length as the fourth; the second and third are 
longest, 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 
vives 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 
ereen, 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.
