made, has the tail not rounded, but emarginate.

Warbler.

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.

Bill of moderate length, similar in form to that of Sylvicola,

differing only in being a little decurved. The general form does not

differ materially from that of Sylvicola, the head being ovate and of

moderate size, the neck short, the body rather slender; the feet of

moderate length, slender; tarsus slender, much compressed, longer

than the middle toe with its claw, anteriorly covered with eight

scutella, of which the upper are blended; toes of moderate size, hind

toe proportionally large, lateral toes equal, fourth adherent at the

base; claws rather long, arched, much compressed, laterally grooved,

very acute. Plumage soft and blended. Wings rather short, convex,

considerably rounded, the third and fourth quills longest, the fifth

little shorter. Tail of moderate length, rounded, always plain, or

without white spots.

Ground-Warbler.--Macgillivray's Warbler.

Plate CCCXCIX. Fig. 4. Male. Fig. 5. Female.

Wings rather short, the second quill longest, the fourth longer than
