Form rather stout, head and body much flattened. Head once and 

 one-third to once and a half as long as broad, its depth equalling the 

 <listance between the centre of the eye and the tympanum ; snout

 longer than the head.

 short,* nasal sometimes forming a suture with the anterior loreal ; 

 fx'ontal as long as or shorter than its distance from the end of the 

 snout ; series of granules between the supraoculars and the super- 

 ciliaries usually complete ; occipital much shorter, and often broader 

 than the interparietal ; parietal more or less distinctly emarginate on 

 the side t for the accommodation of a large supratemporal, which is 

 usually in contact with the upper postocular ; temporal scales granular ; 

 masseteric and tympanic shields usually largej ; usually four, sometimes 

 three or five, upper labials anterior to the subocular. 



25 to 34 scales and granules in a straight line between the symphysis 

 of the chin-shields and the median collar- plate ; gular fold absent or 

 feebly marked. Collar-edge entire; 7 to 11 collar-plates. 



Scales on body oval or oval-hexagonal, more or less distinctW keeled, 



* Sometimes forming a suture with the frontonasal.
