LacertiliaLac`er*til"i*a\, n. pl. [NL., fr. L. lacertus a lizard.] (Zo["o]l.) An order of Reptilia, which includes the lizards. Note: They are closely related to the snakes, and life the latter, usually have the body covered with scales or granules. They usually have eyelids, and most of then have well-formed legs; but in some groups (amphisb[ae]na, glass-snake, etc.) the legs are wanting and the body is serpentlike. None are venomous, unless Heloderma be an exception. The order includes the chameleons, the Cionocrania, or typical lizards, and the amphisb[ae]nas. See Amphisb[ae]na, Gecko, Gila monster, and Lizard.
