The Greek Tortoise, _Testudo Græca_, is of small dimensions, scarcely exceeding twelve inches in length. They inhabit Greece, Italy, some of the Mediterranean isles, and the south of France, from whence it seems to have been transplanted into Italy. They feed upon herbs, roots, slugs, and lob-worms. Like all their race, they sleep during the winter, passing this season in holes which they excavate in the soil sometimes more than thirty inches deep. As the month of May approaches they issue from their retreat, resorting to some sheltered sandy place, where they bask themselves in the sun's rays. Towards the month of June the females lay from twelve to fourteen white spherical eggs, as large as a small walnut; they dispose these eggs in a hole exposed to the sun; but covered over with earth. Thus the operation of hatching is performed. The carapace of this species is oval and very much arched; their marginal plates are twenty-five in number; the plastron, which is almost as long as the carapace, is separated into two great portions by a longitudinal line; the plates of the carapace are spotted with black and greenish yellow, forming a large marbled pattern; the centre of the disc is besides relieved by a small, irregular, blackish, central spot. These three species are held in high estimation on account of their flesh, which gives an agreeable taste to soup. The Elephantine Tortoise, _Testudo elephantina_, the length of which is more than three feet, inhabits most of the islands situated in the Mozambique Channel--namely, between the eastern coast of Africa and the Isle of Madagascar. The Museum of Natural History at Paris had specimens of this Tortoise which lived more than twelve months, and which weighed about six hundred pounds. Their flesh is extremely delicate, and much sought after. In some other Terrestrial Tortoises, from which the genus _Pyxis_ has been formed, the anterior portion of the plastron is movable; and when the head and feet are drawn in, the animal can fasten itself against the sides of the carapace like a door in its case. In some Terrestrial Tortoises, which have been formed into particular genera, the carapace is flexible, and can lower itself behind like the plastron; these are _Kinixys_. Lastly, there are others which, for legs, have only four unguiculated toes: such as the _Homopodes_. MARSH TORTOISES.
