lining, white edging of the inner webs of all the quills, of the outer webs of the inner second-

edges of the greater coverts. Tail blackish, with square white spots on the middle of the inner 
webs of all the feathers excepting the middle pair. Bill blackish; feet dark. Length 4.75-

around eye. Below, yellow, generally pure and continuous, 
sometimes partially replaced by gray ; black streaks wanting, 
or few and confined to the sides. Wings with two bars ; tail- 
spots as in the adult. While the sexes of this dainty little 
species are quite similar, the young require looking after ; ob-

and extensively or completely yellow under parts. Eastern 
N. Am., N. to Hudson's Bay and Great Slave Lake, W. to 
the Rocky Mts. of Colorado ; abundant, chiefly migratory m warbler, nat. size. (Ad nat. del.

126. D. tigri'na. (Lat. tigrina, striped like a tiger, tigris.) Cape May Warbler. Adult $y 
in spring : Back yellowish -olive, spotted with black ; crown in high plumage perfectly black, 
usually interrupted with olive. Rump, sides of the neck nearly meeting across the nape, sides 
of head and entire under parts bright yellow ; ear-patch orange-hrown ; a black transocular 
stripe, cutting off a yellow superciliary stripe ; lower throat and whole breast and sides thickly 
streaked with black ; yellow of throat sometimes tinged with orange-brown ; that of belly and 
under tail-coverts pale or whitish. Wing-bars fused in a large white patch, formed by middle

known W. to the Mississippi. Another exquisite, resembling the Magnolia in its yellow rump 
and yellow black-striped under parts, but easily recognized at maturity by the orange-brown 
ear- coverts ; possessing also the charm of rarity in most parts. It is also remarkable for the 
curved and very acute bill, and some anatomical peculiarities of the tongue, which have caused 
it to be made type of a genus Perissoglossa. Breeds in portions of New England and north- 
ward ; nest low in trees ; eggs not peculiar.

its upper arm running through eye, its lower arm connecting with a series of black streaks 
along the whole sides of the neck and body ; tail-blotches very large, occupying most of the 
inner web of the outer feathers. The sexes are almost exactly alike, and the young only differ 
in not being so bright and in having the dorsal patch and head-markings obscure. Small : 
Length 4.75; extent 7.00-7.40; wing 2.15-2.25; tail 2.00. Eastern U. S. to Massachu-
