bled the lively chant of the Maryland Yellow-Throat, 
even to the wetitshee, yet they were more agreeably va- 
ried, so as to approach, in some degree, the song of the 
Summer Yellow-bird ( Sylvia cestiva). This remarkable 
note, indeed, set me in quest of the bird, which I follow- 
ed for some time, but, at last, perceiving himself watch- 
ed, he left the garden. As far as I was able to observe 
this individual, he was above of a dark olive-green, very 
cinereous on the fore part of the head, with a band of 
black through the eyes, which descended from the sides 
of the neck where at length it joined with a crescent of 
dusky or black spots upon the breast ; the throat was 
yellow and the under parts paler. 
This species, if such it may be considered, is 5 inches long, and 7 
in alar extent. Above deep greenish olive ; tips of the wings and 
centre of the tail-feathers brownish. Head dark, almost sooty-grey. 
Crescent of the breast formed of alternate transverse lines of pure 
white, and deep black ; below yellow. Legs and feet (as in the pre- 
ceding) pale flesh-color. Bill dusky above, lighter below. Iris 
hazel. 
DUSKY WARBLER. 
(Sylvia carbonata, Audubon, pi. 60. Orn. Biog. i.p. 30S.) 
Sp. Char act. — Crown and front black; above dark olive-green, 
spotted with black ; throat, sides of the neck, and line over the 
eye, yellow ; below yellowish olive and darkly spotted ; two light 
bands on the wings. 
This new species was obtained by Audubon near the 
village of Henderson in Kentucky. The only two indi- 
viduals met with were males, not yet arrived at perfect 
plumage. Their actions and food appeared very similar 
with those of other Warblers. 
Rump yellowish ; tail emarginate, dusky. A white band on the 
wing formed by the margins of the upper coverts, also a yellowish 
one below. Bill dusky. Legs flesh-colored. Iris hazel.
