hind limb is contained thrice and one third in the distance between 
axilla and groin. Fourth toe slightly longer than third. The 
frontal a little longer and forming a very short suture with the 
frontonasal. ‘Colour above olive-brown, with an iridescent blue 
tinge, purer brownish on the tail, pale brownish olive at the sides of 
the body ; each scale, above and at the side, is indistinctly mottled 
with dark, and there are generally a few white spots on the side of 
the neck and about the shoulder; a narrow white, slightly black- 
margined band rises from behind the orbit and continues on each 
side of the back; it becomes indistinct in the middle of the body, 
but is again slightly more conspicuous above the hip, gradually 
disappearing on the tail, which is indistinctly speckled with dark 
brown at the sides.”
