Anilius scytale (Oken 1816) is medium-sized burrowing snake., reaching 27 inches (70 cm) in length. The eyes are covered beneath a clear scale. It feed on small reptiles, amphibians and even other blind snakes.Here it descends from a sister to Lanthanotus and gives rise to Cylindrophis and other smaller burrowing blind snakes. It has a vestigial pelvis with limbs visible as a pair of cloacal spurs. It is ovoviviparous.
