There is no veil nor operculum. (MM. Reynaud, and Quoy and Gaymard have observed that, under certain circumstances, the hinder part of the foot is spontaneously amputated.) We recog the Purpura, Brug., by its flattened columella, pointed at the base, and forming there, with the outer lip, a canal excavated in the shell, but not projecting. The species were scattered among the Buccina and Muricea by Lin- naeus. Their snail is like that of Buccinum as now restricted. Some shells similar to Purpura, but in which we notice a spine on the outer margin of the canal, form the genus Licorna, Montf. (Monoceros, Lam.) Others in which the columella, or at least the lip, is garnished, in the full-grown shell, with teeth that narrow the mouth, constitute the SHttra of the former, and the Ricinula of Lamarck. The Concholepas, Lam., baa also the 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 (fiuecinum concholepas, Brug.) is the only one known. Cassis, Brug.—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 turned up backwards, and to
