SPECIES 32. SYLVM AGILIS. 
CONNECTICUT WARBLER. 
[Plate XXXIX.— Fig. 4.] 
This is a new species, first discovered in the state of Connec- 
ticut, and twice since met with in the neighbourhood of Phila- 
delphia. 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 j^ale flesh colour; 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 hav- 
ing the throat of a dull buff colour 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.
