supraoculars, bordered internally by a series of moderate-sized 
scales; usually two canthal scales ; occipital as long as broad, much 
larger than the parietals, which are sometimes divided in two pairs ; 
anterior border of ear with a strong denticulation formed by three 
or four pointed scales, which are as large as or a little larger than 
those preceding. Dorsal scales much larger than ventrals, as broad 
as long, moderately keeled, with more or less distinctly denticulated 
posterior border, nut or but shortly mucronate, forming parallel 
longitudinal series; twenty-seven to thirty-four scales between the 
occipital shield and the base of the tail; five to seven scales, taken 
in the middle of the back, correspond to the length of the shielded 
part of the head; lateral scales keeled, directed obliquely upwards 
and backwards, as large as or slightly smaller than the dorsals ; 
ventrals smooth, entire, or bi- or tricuspid; thirty-eight to forty- 
two scales round the middle of the body. The adpressed hind limb 
reaches the cervical fold or the ear; tibia as long as the shielded 
part of the head ; the distance between the base of the fifth toe and 
the extremity of the fourth equals or slightly exceeds the distance 
between the end of the snout and the ear. Fitteen to twenty 
femoral pores on each side. Caudal scales about as large as dorsals, 
strongly mucronate. Male with large postanal scales. Olive above, 
uniform or black-spotted ; a broad, black, yellow-edged band from
