2. Bill serrated; head with an erect compressed crest; tail very long, cuneated. America. CALURUS. _Sw._ 3. Bill entire. Inhabits tropical Asia. HARPACTES. _Sw._ 4. Bill with obscure serratures: tarsi naked, covered with scales; the two anterior toes divided nearly to their base. (_Type_, Trogon Narina). Africa. APALODERMA. _Sw._ ---- SPECIFIC CHARACTER. _Female. Breast and upper plumage olive brown; body and under tail covers crimson; front, chin, and ears grey; wing covers lineated with undulate dusky lines; two middle tail feathers ferruginous brown, with black tips._ ---- We have already given the general reader some account of the manners of these very singular birds, and we have said more upon them in _North. Zool. Vol. 2_. Having figured the male on our 82nd plate, we now exhibit, in the female, that remarkable difference between the sexes, which pervades all the species. Our figure and specific character renders a detailed description of the plumage unnecessary; it should be observed, however, that the lateral tail feathers, in the female, are without those two black transverse bands on the inner web, towards the tip, which are so conspicuous in the male. There is another species from Mexico, which country seems to be the most northern range of these birds. We feel gratified at being able to characterize four typical forms of the genus; all of which, at the same time, are marked by geographic peculiarities. * * * * * * [Illustration: ACHATINELLA.

See pl. 99. ---- SPECIFIC CHARACTER. _Shell ovate-oblong, subventricose, whiteish, with chesnut bands; spire thickened, the tip pale brown._ Achatinella bulimoïdes. _Sw. in Brands Journ. Ap. 1828. p. 85._ ---- We continue our Illustrations of these pretty little land-shells, of which all the species, as we before remarked, are natives of the South Sea Islands, and very little known to collectors. The present is distinguished by the thickness of its spire, the apex being more suddenly pointed. We have represented two varieties in point of colour, but in both the suture is scarcely, if at all, margined by an indented grove. ---- ACHATINELLA livida, _Livid Achatinella_. ---- SPECIFIC CHARACTER. _Shell reversed, ovate, obtuse, livid brown or greyish; spire thickened; suture with a deep fulvous line._ Achatinella livida. _Brands Journ.
