; order Squamata, suborder Sauria)
A family of reptiles whose members vary from four-legged lizards to legless snake-like forms (e.g. Anguis fragilis, the slow-worm or blindworm, and Ophisaurus apodus, the European glass lizard or glass snake). All have a forked tongue (unlike skinks of similar form), mobile eyelids, and tail autotomy. Some (e.g. A. fragilis) are ovoviviparous, others (e.g. O. apodus) egg-layers. There are about 40 species, found in America, Europe, Asia, and N. Africa.
