SPECIES 10. SYLVM PHILADELPHIA. 
MOURNING WARBLER. 
[.Plate XIV. — Fig. 6.] 
I HAVE now the honour of introducing to the notice of natu- 
ralists and others, a very modest and neat little species, which 
has hitherto eluded their research. I must also add, with regret, 
that it is the only one of its kind I have yet met with. The bird 
from which the figure in the plate was taken was shot in the 
early part of June, on the border of a marsh, within a few miles 
of Philadelphia. It was flitting from one low bush to another, 
very busy in search of insects; and had a sprightly and pleasant 
warbling song, the novelty of which first attracted my atten- 
tion. I have traversed the same and many such places, every 
spring and summer since, in expectation of again meeting with 
some individual of the species, but without success. I have, how- 
ever, the satisfaction to say, that the drawing was done with 
the greatest attention to peculiarity of form, markings and tint 
of plumage; and the figure on the plate is a good resemblance 
of the original. I have yet hopes of meeting, in some of my ex- 
cursions, with the female; and should I be so fortunate, shall 
represent her in some future volume of the present work, with 
such further remarks on their manners, &c. as I may then be 
enabled to make. 
There are two species mentioned by Turton to which the 
present has some resemblance, viz. Motacilla mitrata, or Mi- 
tred Warbler, and M. cucuUata, or Hooded Warbler, both birds 
of the United States, or more properly a single bird; for they 
are the same species twice described, namely, the Hooded War- 
bler. The difference, however, between that and the present is 
so striking, as to determine this at once to be a very distinct
