Scales small anteriorly, becoming larger on the tail. The height

 head, and more than the width of the interorbital space. The jaws 

 are nearly equal in length ; the cleft of the mouth is obHque, and

 teeth of the outer series are slightly enlarged. Streaks of minute 

 warts on the sides of the head, but none on the neck. None of the
