The male Fan throated lizard (Sitana ponticeriana) (13 pics)

Upper head-scales small, sharply keeled; canthus rostralis and supraciliary edge sharp, with much enlarged scales. Dorsal scales larger than ventrals, with sharp keels forming straight longitudinal lines; lateral scales smallest, uniform or intermixed with scattered enlarged ones. The fore limb does not extend on to the vent, if laid backwards; the hind limb reaches to the orbit, if laid forwards; the lower thigh is rather shorter than the foot (measured from the heel to the tip of the longest toe), the length of which is only three-fourths of the distance between the shoulder and hip joints. Limbs above with uniform strongly keeled scales.
