The bird described below, a sombre exception to a particularly brilliant family, I cannot refer to any species with which I am familiar; it may, however, be the female of a recorded species. I regret that I did not ascertain the sex of the individual described, the only one that ever fell into my hands. Nor can I give any information concerning it, but that it was shot by Sam, at Basin-spring, on the 8th of October, hopping about low bushes. ARROW-HEADED WARBLER.[43] _Sylvicola pharetra._—+Mihi.+ [43] Length 5⁴⁄₁₀ inches, expanse 8 (nearly), flexure 2¹¹⁄₂₀, tail 2, rictus about ⁶⁄₁₀? tarsus ⁷⁄₁₀, middle toe ⁵⁄₁₀. Irides hazel; beak black above, suture and lower mandible grey; feet purplish horn, with pale soles. Head, neck, back, less coverts, chin, throat and breast, mottled with black and white, each feather being grey at the base, and black, bounded on each side by white, at the tip. The black preponderates on the upper parts, the white on the breast, where the black spots take arrow-headed forms. Wing-quills and coverts black; the first primaries have the middle portion of their outer edge narrowly white, and those from the third to the seventh inclusive have a more conspicuous white spot at the basal part of the outer edge. The secondary greater coverts are tipped outwardly with white, the medial coverts more broadly; and these form two bands, but not very notable. Plumage of rump and tail-coverts unwebbed, brownish-grey. Tail-feathers black, with paler edges, the outmost two or three tipped inwardly with white. Sides, thighs, and under tail-coverts grey, with indistinct black centres. Belly greyish white. This is another species, of which I have but a single specimen. It was shot on the 9th of February, in Bognie woods, on the top of Bluefields Peak. I know nothing of its manners, but that it was engaged, as Warblers commonly are, hopping on trees, and peeping for insects. The specimen was a male. Its general aspect is like that of the Black and white Creeper, but it may be distinguished at once by comparison; the colours in _that_ being distributed in greater masses, and disposed in broad stripes; in _this_, in small mottlings, or thick spotting, which difference is especially observable on the head. The beak, also, though partly shot away in my specimen, is decidedly that of a _Sylvicola_. +Fam.+—MUSCICAPADÆ.—(_The Flycatchers._) REDSTART FLYCATCHER.[44] _Setophaga ruticilla._ _Musicapa ruticilla_, +Linn.+—Aud. pl. 40. _Motacilla flavicauda_, (_fem._) +Gmel.+ _Setophaga ruticilla_, +Sw.+ [44] Length of 5³⁄₈ inches, expanse 7¹⁄₂, flexure 2⁶⁄₁₀, tail 2¹⁄₄, rictus ¹¹⁄₂₀, tarsus ⁸⁄₁₀, middle toe ⁵⁄₁₀.
