. Cuvier's animal kingdom : arranged according to its organization. Animals. From the observations of Van Hasselt it seems that we must here arrange The Scarabes, Montf. The shell is oval, and the aperture contracted by large teeth projecting from both the columellar side as well as the outer lip : tliis lip is swollen, and as the animal re-makes it after every half-whorl, the shell is most protuberant on two opposite lines, and has a flattened aspect. The animals live on aquatic plants in the Intlian Archipelago. The two genera which follow were misarranged among the Volutes. AuRiccLA, Lam., — Differing from all preceding aquatic Pulmonea by having their columella striated with large obhque channels. Their sliell is oval or oblong; the aperture of the shape of the Bulimus or Limnîeus ; the lip furnished with a varix. Several species are of considerable bulk ; but it is not ascertained if they Uve in marshes, like the Limnajus, or merely upon their margins, after the manner of the Succinea. [One species, according- to Lesson, lives in fresh water ; the others appear to be terrestrial, living on rocks by the sea-side.] We find only one in France, from the coast of the Mediterranean {Auricula myosotis, Drap.) The male has two tentacula, and the eyes are at their bases. [Carychium, Muller, answers so nearly to the description of Auricula, that the genera ought probably to be conjoined. The typical species (C. minimum) lives under leaves in shaded woods.] The Melampes, Montf. (Conovuhcs, Lam.), Like the Auricula, have prominent plaits on the columella, but their aperture has no varix, and its inner lip is finely striated : the shell has somewhat the shape of a cone, of which the spu'e makes the base. They inhabit the rivers of the Antilles. Fig. 163.- -icuU scarabseus. THE SECOND ORDER OF THE GASTEROPODES. THE NUDIBRANCHIATA.* They have neither a shell nor pulmonary cavity, but their branchiae are exposed naked upon some part of the back : they are all hermaphroditica
