 longer than the diameter of the orbit, with angular canthus rostralis ; 

 nostril large, directed backwards, nearly equally distant from the eye 

 and the end of the snout ; tympanum nearly half the diameter of 

 the orbit ; upper head-scales keeled, largest on the snout ; a trans- 

 verse series of larger scales borders the head posteriorly, forming a 

 right angle with another series above the ear. Sides of neck with 

 group of spines ; no distinct dorso-lateral fold. Gular scales as large 

 as ventrals, feebly keeled, more or less strongly mucronate, sometimes 

 produced into spines. Body much depressed ; scales on the middle 

 of the back largest, unequal, keeled, the enlarged ones sometimes 

 forming transverse series ; on the sides, the scales almost granular and 

 intermixed with numerous erect conical spines ; ventral scales feebly 

 keeled. Limbs, and especially digits, short ; the adpressed hind 

 limb reaches the axilla or the shoulder ; four or five femoral and two 

 or three praeanal pores on each side. Tail round, depressed at the 

 base, once and a half to twice as long as head and body, above with 

 large unequal strongly keeled or spinose scales forming more or less 

 regular cross series. Brown above, uniform or with symmetrical 

 darker markings ; usually a black spot on each side of the neck ; 

 lower surfaces brown or brownish, uniform or with lighter or darker
