black, primaries edged with, pale blue, the first and second row of coverts 
broadly tipped with pale yellow, secondaries broadly edged with the 
same ; tail black, handsomely forked, exteriorly edged with ash, the 
inner webs of the three exterior feathers with each a spot of white ; 
from the extremity of the black at the lower mandible, on each side, a 
streak of deep reddish chestnut descends along the sides of the neck, 
and under the wings to the root of the tail ; the rest of the lower parts 
are pure white ; legs and feet ash ; bill black ; irides hazel. The female 
has the hind head much lighter, and the chestnut on the sides is con- 
siderably narrower and not of so deep a tint. 
Turton and some other writers have bestowed on this little bird the 
singular epithet of bloody-sided, for which I was at a loss to know the 
reason, the color of that pa.rt being a plain chestnut ; till on examining 
Mr. Edwards's colored figure of this bird in the public library of this 
city, I found its side tinged with a brilliant blood color. Hence, I sup- 
pose, originated the name. 
Species X. SYLVIA PHILADELPHIA. 
MOURNING WARBLER. 
[Plate XIV. Fig. 6.] 
I have now the honor of introducing to the notice of naturalists 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 
attention. 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, however, the 
satisfaction to say, that the drawing was done with the greatest atten- 
tion 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 excursions, 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
