Bill conical, attenuated, iloprcssed at the base, where it is, however, scarcely broader than high, compressed from the mid- dle. Culmen straiijht for the basal half, then rather rapidly curving, the lower edge of up- per mandible also concave. Gonys slighlly convex and ascending. A distinct notch near the end of the bill. Bristles, though short, generally quite distim-t at the base of the bill. Tarsi long; deci<ledly longer than middle toe, which is longer than the hinder one; the claws ratht small and much curved; the hind claw nearly as long as its digit. The wings long and pointed; the second quill usually a very little longer than the first. The tail slightly rounded and emarginate. Colors. Tail always witli a white or yellow spot; its ground-color never clear olive- green. In D. (psfiva edged internally with yellow. Eggs usually with a white or a bluish-white ground, marked with purplish-brown and obscure lilac; in some, mingled with varying shades of sienna-brown. Nest, so far as known, in bushes and trees, except D. palmarum^ which is on the ground. The genus Dendroica is one of the most extensive as to species of any in North America, and scarcely admits of any subdivision. There is a little vari- ation in the bill, wings, etc., the chief peculiarities being in D. castanca and pennsylvanica, in which the bill is broader, and more depressed, with longer bristles ; in D. striata, where the bill is narrow with scarcely any bristles ; and in D. palmarum and kirtlaiidi, where the wings are very short, scarcely longer than the tail. D. palmarum has the tarsus unusually lo
