length and slender. The fore-limb, when laid forward, nearly or fully reaches 

 the opening of the ear, and is only a little shorter than the distance between 

 the snout and the ear ; the hind limb is less than half the distance 

 between the axil and loin, and it barely exceeds the distance between the 

 fore limb and the anterior angle of the eye. 



Colour, above, olive brown, with an iridescent blue tinge, purer brownish 

 on the tail, pale brownish olive at the side of the body ; each scale, above 

 and at the sides, 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 ; 

 Hmbs above with longitudinal, broken up, dark hues ; chin and anterior neck 

 below yellowish, vent whitish ; tail below brownish white. 



This description is drawn up from a specimen which was presented to 

 the Indian Museum by Mr. W. Theobald, and is not unlikely the same which 

 he in his Catalogue of Imrmese Reptiles noticed under the name of R. Boiv- 

 ringi The greater length of the limbs and the coloration readily distinguish 

 tins from the preceding species.

 The differences in structure between these three species are very few. 

 In the first and third the vertical and the median occipital shield are 

 comparatively narrower and longer, than in the second. 



In JR. albopunctata the scales of the body are slightly smaller and more 

 quadrangular, the number of longitudinal rows varies between 26 and 28, (the 

 two numbers being almost equally common, at least in Bengal specimens), the 

 transverse rows between fore and hind limb vary between 50-60, 56 being the 

 most usual number, as stated by Gunther. The fore leg reaches, when laid for- 

 ward, to the front edge of the ear, or a little beyond it, rarely to the angle of the 

 mouth ; the length of the hind leg is generally a little less than \ th of the 

 body, rarely exactly ^th. 



In It. Sardwickii all the scales are somewhat larger and more trans- 

 versely elongate, the number of longitudinal rows varies between 24 

 and 26, both being almost equally common ; the transverse rows between 

 fore and hind limbs vary between 48 and 56, 53 being the most usual
