n. A small European lizard, Anguis fragilis, of the family Anguidæ, having a slender limbless body and tail, like a snake, rudimentary shoulder-girdle, breast-bone, and pelvis, a scaly skin, concealed ears, and small eyes furnished with movable lids: so called because supposed to be a sightless worm, a notion as erroneous as is the supposition that it is poisonous. Also called orvet and slow-worm.
