Species XXXII. SYLVIA AGILIS. 
CONNECTICUT WARBLEK. 
[Plate XXXIX. Fig. 4.] 
This is a new species, first discovered in the state of Connecticut, 
and twice since met with in the neighborhood of Philadelphia. As to 
its notes or nest, I am altogether unacquainted with them. The different 
specimens I have shot corresponded very nearly in their markings ; two 
of these were males, and the other undetermined, but conjectured also 
to be a male. It was found in every case among low thickets, but 
seemed more than commonly active, not remaining for a moment in the 
same position. In some of my future rambles I may learn more of this 
solitary species. 
Length five inches and three quarters, extent eight inches ; whole 
upper parts a rich yellow olive; wings dusky brown, edged with 
olive ; throat dirty white, or pale ash ; upper part of the breast dull 
greenish yellow ; rest of the lower parts a pure rich yellow ; legs 
long, slender, and of a pale flesh color ; round the eye a narrow ring 
of yellowish white ; upper mandible pale brown, lower whitish ; eye 
dark hazel. 
Since writing the above I have shot two specimens of a bird which in 
every particular agrees with the above, except in having the throat of a 
dull buff color instead of pale ash ; both of these were females, and I 
have little doubt but they are of the same species with the present, 
as their peculiar activity seemed exactly similar to the males above 
described. 
These birds do not breed in the lower parts of Pennsylvania, though 
they probably may be found in summer in the alpine swamps and 
northern regions, in company with a numerous class of the same tribe 
that breed in these unfrequented solitudes.
