series of four to six traiisversel}' enlarged supraoculars, sometimes 

 broken up, bordered inwards by one series of scales and separated 

 from the supraciliaries by two or three ; two canthal scales ; three or 

 four more or less enlarged scales form a deaticulation on the 

 anterior border of the ear. 



Dorsal scales much larger than ventrals, as broad as long or 

 broader than long, obtuse or truncate, not or but very shortly 

 mucronate, feebly keeled, sometimes nearly smooth, forming 

 parallel longitudinal series ; 38 to 46 scales between the inter- 

 parietal shield and the base of the tail, 8 to 11 corresponding to 

 the length of the shielded part of the head. Lateral scales keeled, 

 directed obliquely upwards and backwards, as large as or larger 

 than the dorsals. Ventral scales small, smooth, entire or bicuspid. 

 46 to 54 scales round the middle of the body. 



The adpressed hind limb reaches the axilla, the shoulder, or the 

 cervical fold ; tibia nearly as long as the shielded part of the head ; 

 the distance between the base of the fifth toe and the extremity 

 of the fourth equals or slightly exceeds the distance between the 

 end of the snout and the ear. 8 to 17 femoral pores on each side. 



Caudal scales larger than dorsals, more or less strongly keeled, 

 pointed or shortly mucronate, spinose on the sides. Males with 

 enlarged postanal scales.
