Height 15 — 22; head 8 — 9, more than 3 to 3.5 in trunk. 

 Head and trunk equal to or about one tenth shorter than tail. 

 Eye 8 — 11, about in the middle above the cleft of the mouth. 

 Snout rather short, less than twice diameter of eye. Anterior 

 nostrils in a very short tube. Cleft of mouth 2.3 — 2.5 in length 

 of head. The mouth can be shut completely. Dorsal mode- 

 rately developed, beginning before gillopenings, which are about 

 equal to diameter of eye. In the maxillaries on each side a 

 row of about 11 — 15 compressed conical teeth, in young 

 specimens there is anteriorly an inner row of 3 long and slender 

 teeth. On the intermaxillary plate a peripheral series of 8 — 10 

 long teeth, with some smaller teeth between them, and a 

 median series of 3 or 2 fang-like ones. Vomer with two series 

 of small conical teeth, diverging anteriorly and forming one
