 Sides minutely granulate. 42 plates and granules round the middle of 

 the body. Preanal plate rather small, bordered by one semicircle 

 of small smooth plates. 



Upper surface of limbs with rhombic keeled scales. 4 femoral 

 pores on each side.t 28 lamellar scales under the fourth toe. 



Caudal scales strongly keeled and shortly mucronate, the whorls alter- 

 nately a little longer and a little shorter, the fourth containing 18 scales. 



Olive-brown above, the dorsolateral area (two rows of plates) 

 lighter ; two blackish streaks, formed of spots close together, along the
