 keeled scales ; another parallel series of enlarged scales on each side

 enlarged keeled scales are scattered on the ilanks, and frequently 

 others form angular series across the back ; ventral scales as large 

 as the enlarged dorsals, feebly keeled. Limbs above with unequal 

 strongly keeled scales ; fourth finger longer than third ; the ad- 

 pressed hind limb reaches the eye or the tip of the snout. Tail not 

 compressed, twice to twice and a half as long as head and body, 

 covered with rather unequal keeled scales. Brownish-grey or blue 

 above, uniform or with angular brown markings on the back ; lateral 

 nuchal denticulation brown-edged ; lower surfaces uniform whitish 

 or with small black dots.
