'We reco'^nize the Purpura, Urns'., ^V ''^ llattened columella, pointed at the base, and formin;^- there, with the outer lip, a canal in the shell, but not projecting. The species were scattered among' the Buccina and Murices by Lin- naeus. Their snail is like that of Buccinum as now restricted. Some shells similar to Puipura, but in which we notice a spine on the outer margin of the canal, form the genus Licorita, Montf. (Munocercs, Lam.) Otiiers in which the columella, or at least the lip, is garnished, in the full-grown shell, with teeth tliat narrow the mouth, constitute the of the former, and the liicinula of Lamarck. The Concholcpas, Lmu., has also tb'.' general characters of the Purpura, but the aperture is so enormously large and the spire so inconsiderable, that the shell has the aspect of a Capulus, or of one of the valves of an Area. The emargination of the mouth has a small tooth on each side of it. The ani- mal resembles that of Buccinum, excepting in the foot, which is enormous in width and in thickness, and which is attached to the shell by a muscle in form of a horse-shoe, as in Capulus. There is a thin, narrow, horny operculum. A species from Peru (Buccinum concholepas, Brug.) is the only one known. Cassis, Mmg.—Shell oblong; the aperture oblong or narrow; the columella covered with a plate as in Nassa, and that plate grooved transversely as well as the outer lip : the emargination ends in a short canal, which is folded and
