[Line drawing: _Perissoglossa tigrina_, Baird.] GEN. CHAR. Form of _Dendroica_, but bill slender, acute, with very obsolete notch; the commissure gently arched or curved from the base; the gonys also straight, or even slightly concave. Tongue lengthened, narrow, deeply bifid (for one third), and deeply lacerated or fringed externally at the end; the edge along the median portion folded over on the upper surface, but not adherent. The curvature of the bill in _Perissoglossa tigrina_ is quite peculiar among the _Sylvicolidæ_ with notched bills. Some Helminthophagas (without notch) approximate this character, though in none, excepting _H. bachmani_, is it in equal amount,—all the others having the gonys very slightly convex, instead of straight, or even slightly concave. It is most probable that the _Helinaia carbonata_ of Audubon belongs here, as it appears very closely allied to the type of this genus. The two species may be distinguished as follows:— COMMON CHARACTERS. _Male._ Top of head black. Above olive, becoming yellowish on rump. Head, neck, and lower parts bright yellow, becoming whitish posteriorly. Dorsal feathers with black centres; breast and sides streaked with black. A black streak through the eye. P. tigrina. Large white patches on inner webs of tail-feathers. Sides of head and middle of throat tinged with chestnut. One large white patch on wing, covering both rows of coverts. Outer web of lateral tail-feather blackish. P. carbonata. No white patches on tail-feathers. No chestnut about head. Two bands on the wing, the anterior one white, the posterior yellow. Outer web of lateral tail-feather whitish. Perissoglossa tigrina, BAIRD. CAPE MAY WARBLER. _Motacilla tigrina_, GMELIN, Syn. Nat. I, 1788, 985. _Sylvia tig._ LATH. _Dendroica tig._ BAIRD, Birds N.
