Sylvia tigrina, Bonap. Syn. p. 83; but not of Gmelin or Latham, as the figure of Edwards, to which reference is made, has the tail not rounded, but emarginate.

99. 24. Sylvicola agilis, Wils. Connecticut Wood Warbler. – Connecticut Warbler

Plate CXXXVIII. Male and Female.

Wings long, with the first quill longest, and exceeding the first secondary by eleven-twelfths of an inch; middle toe and claw longer than the tarsus; tail of moderate length, nearly even, with acuminate feathers. Male olive-green above; a ring of yellowish-white round the eye; the head, neck all round, and part of the breast ash-grey, the sides greyish-green; the rest of the lower parts bright yellow. Female olive-green above, yellow beneath, the sides of the neck and a band across the breast tinged with brown.

Connecticut Warbler, Sylvia agilis, Nutt. Man. v. i. p. 399.

This species forms a connecting link between Sylvicola and Trichas, having the long pointed wings of the former, and the general appearance of the latter, which it resembles, especially in its tail, which is neither emarginate, nor marked with the white spots seen on that of almost all the other Sylvicolæ, but which do not exist in the genus Trichas. Some of the Sylvicolæ are, in like manner, assimilated to Myiodoctes, and others to Vermivora. Of the former may be mentioned, Sylvicola Auduboni and S. coronata; of the latter, S. Blackburniæ.

GENUS III. TRICHAS, Swains. GROUND-WARBLER
