Bipes is a genus of amphisbaenians (or worm lizards) found only in Mexico, the sole living member of the familyBipedidae.[2] They are carnivorous, burrowing reptiles, but unlike other species of amphisbaenians, they possess two stubby forelimbs placed far forward on the body.[3] They also retain an almost complete pectoral girdle.[4] The shovel-like limbs are used to scrape away soil while burrowing, in a manner similar to a mole.[5] Evidence for their occurrence in the United States is reviewed by Somma (1993).
