The animal kingdom : arranged after its organization, forming a natural history of animals, and an introduction to comparative anatomy . GASTEROPODA 365 foot, pointed beliiiul, widened n front, wnere it is marked with two deep emnrgmations. Tlie eyes ore on the sides of the tentnculn, near the liase. There is no veil nor operculum. ( lleynaud, and Quoy and Gaymaid have observed that, under certain circumstances, the hinder part of the foot is spontaneously amputated.) We recos^niie the Purpura, Bru?., by its flattened columella, pointed at the base, and foruiin? there, with the outer lip, a canal excavated in the shell, but not projecting;. The species were scattered snioiiR the Uuccina and Murices by Lin- nffius. Their snail is like that of Uuccinuni as now restricted. Some shells similar to Iurpura, but in which we notice a spine on the outer marRin of the canal, form the genus Lirorna, Montf. (.Monoceroa, Lam.) Others in which the columella, or at least the lip, is Karniabed, in the full-j;rown shell, with teeth that narrow the mouth, constitute the Shira of the former, and the Ricinula of L
