Text Appearing Before Image:
plastron is much more complete than it is inthat genus, we come first to the Cinostemidse in which the carapaceis more vaulted, although the feet are still webbed, the creatures livingfor the most part in muddy ponds. The most northerly American formis the Musk turtle {Aromochdys odoratus), the secretion from thecutaneous glands of which has a somewhat offensive musky odour.Closely allied are certain more southerly mud-turtles, which are able toclose the shells. 11. Most of our speciesof turtles, however, be-long to the Emydidse, allof which are afjuaticwhen young, some likethe painted turtle (Cliry-siinys pkta), and thespotted turtle {Nanemysguttata) throughout life,while others like the^V*ood turtle {Chelopusinsculj^tus) are found indry jjlaces away fromwater. The most ter-restrial of the family is the common Box-turtle (Cistudo carhmta), inwhich the plastron can be shut up over the retracted extremities. Itlives in sandy hills, and forms burrows into which it retreats during rain.

Fig. 75.—European Land-Tortoise.(After Brehm). Testudo gracca. {. 106 HIGH SCHOOL ZOOLOGY. 12. Finally the Testudinidse embrace tlie truly terrestrial tortoiseslepresciited by one species iu the iSouthern States, but occurring ubuud-autly in the warmer parts of the Old and New Worlds. (l*ig. 75). 13. The genus Hatteria (Fig. 76), refei-red to above is mostnearly related in its habits and form to the Lizards, Lacertilia,but there are some respects in which its structure is muclimore primitive; e.g., its vertebrae are ampliicoelous and itspineal body (I. 36), presents more nearly the structure of aneye than does that of any other living reptile. Unlike tlieLizards its quadrate bone is united firmly with the skull, andby an arch below the eye with the maxilla.
