 on the median line the smallest, the lateral ones larger than the 

 ventrals. Nuchal crest formed of lanceolate spines not quite as long 

 as the diameter of the tympanum ; dorsal crest not continuous with 

 nuchal, formed by about fourteen triangular spines, only every alter- 

 nate median scale being modified into a spine. Dorsal scales large, 

 rhomboidal, rather feebly keeled, the points of the upper scales 

 directed upwards and backwards ; ventral scales smaller than 

 dorsals, strongly keeled. Limbs above with sabequal keeled scales, 

 some of which are spinose ; fourth finger and toe slightly longer 

 than third ; the adpressed hind limb reaches hardly the tympanum.
