Snakes are distinguisheci from most lizards by the absence of limbs, and connected with this the similar vertehne in which only trunk and caudals can be distinguished. The caudals lack ribs, but these are present and long in the trunk region, serving for locomotion and supporting the body on their distal ends. Since there are legless lizards, it is further necessary to say that in the Ophidia the girdles and sternum are lost, only the Peropoda having remnants of the hinder ajipendages and pelvis, but these are not con- nected with the vertebral column. The ventral side of lizards is covered with scales, of reptiles with transverse scutes. Further d
