I have represented this delicate little bird of its natural size; which is so small, as scarcely to equal that of a Lark. The Turnix inhabits the sandy deserts of Africa and India, and seems to form a race of pigmy Bustards, all the species yet discovered (fourteen in number) being very diminutive. Little is known of their habits in a state of nature, further than that they migrate, and fly with great rapidity. The specific character will distinguish _H. nivosus_ as a species; and I have already given a more detailed description of it in the Journal above quoted. Mr. Leadbeater received it from Senegal. * * * * * Pl. 164 [Illustration] SYLVIA annulosa, _White-eyed Warbler._ * * * * * GENERIC CHARACTER.--See Pl. 139. * * * * * SPECIFIC CHARACTER. _S. olivaceo-viridis, infra albescens; jugulo flavescente; palpebris plumis niveis insignibus._ Olive-green, beneath whitish; throat yellowish; eyes encircled by a ring of snowy feathers.

It is far from being peculiar to Madagascar (as Dr. Latham's name of _Madagascariensis_ would seem to imply), but is spread over a wide extent of the eastern hemisphere; being found both in the Isle of France, the Cape of Good Hope, and Madras. The name, therefore, is peculiarly inapplicable; but this is not all: for we find that the same author, a few pages after, has given this identical name to another very different bird; the same error is transferred into Shaw's Zoology. Figure, the size of life: colour above, olive green; ears and sides of the head the same: chin, throat, and under tail covers yellow; breast cinereous, changing to dusky brown on the flanks; the middle of the body whitish; between the eye and bill a velvet-black line, which forms a partial margin to the snowy feathers of the eyelids; wings and tail dusky black, margined with olive. Very indifferent figures of both sexes will be found in Vaillant's African birds; from his description it seems to be a gregarious species. I regret not being able, at this moment, to refer to the work. * * * * * Pl. 165 [Illustration] SYLVIA annulosa, (_var._ [beta].) _White-eyed Warbler._ * * * * * GENERIC CHARACTER.--See Pl. 139. * * * * * SPECIFIC CHARACTER.
