31 to 36 * gular scales iu a straight line bet'weeu the svmijhysis of 

 the chin-shields and the median collar-plate, juxtaposed iu front, 

 larger and imbricate near the collar ; no gular fold. Collar free, 

 curved or, more frequently, angular, composed of 7 to 11 plates.

 obtusely or rather strongly keeled on the body, subimbricate towards 

 the tail, a little smaller on the sides ; 48 to 59 scales across the middle 

 of the body, 20 to 26 in a transverse series between the hind limbs. 



Ventral plates iu regular longitudinal and transverse series, all 

 except the outermost broader than long, but never twice as broad 

 as long, iu 10 longitudinal and 30 to 33 transverse series. 3 or 4 

 preanal plates on the median line, usually very feebly enlarged in 

 females, the last 2 to 3 times as broad as long in males. 



23 to 29 femoral pores on each side,t the two series meeting in the 

 middle. Digits with 3 series of scales ; toes with moderately strong 

 lateral denticulatiou, the denticles stronger on the outer side of the 

 fourth toe but shorter than the diameter of the toe ; 21 to 23 strongly 

 unicarinate lamellis under the fourth toe. 



Upper caudal scales much larger than posterior dorsals, oblique, 

 truncate, and strongly and diagonally keeled, basals as long as broad 

 or a little broader than long, lower smooth or very obtusely keeled
