American legless lizard

The family Anniellidae, known as American legless lizards, contains six species in a single genus Anniella: A. pulchra, the California legless lizard, the rare, A. geronimensis, Baja California legless lizard, and four more discovered in 2013.

Two subspecies of the California legless lizard were formerly recognized, A. p. pulchra, the silvery legless lizard, and A. p. nigra, the black legless lizard. However, modern taxonomic classification considers the black legless lizard to simply be a melanistic form.
