and the tip of the snout. Upper surface of head covered with very 

 strongly keeled scales. Dorsal scales small, the upper largest, 

 strongly keeled, all obliquely directed upwards. Gular and ventral 

 scales strongly keeled, the latter larger than the largest dorsal scales. 

 No femoral or prseanal pores. Upper surfaces olive, with blackish 

 transverse markings across the back, tail, and limbs ; upper surface 

 of head with three obsolete blackish transverse bands, separated by 

 light lines ; a broad blackish band from orbit to tympanum, bordered 

 inferiorly by a light band extending to above the fore limb ; hps 

 light-coloured, variegated with blackish ; lower surfaces whitish, 

 dotted all over with blackish.

Length of snout measuring twice the diameter of the eye. Nasal 

 divided ; loreal slightly higher than broad ; one prae- and two post- 

 oculars ; temporals 1 + 2 ; seven upper labials, the third and fourth 

 entering the orbit ; four inferior labials in contact with anterior 

 chin-shields ; latter, hinder pair three fifths the length of anterior 

 pair. The portion of the rostral seen from above is as long as the 

 suture between the internasals and the praefrontals ; latter con- 

 siderably higher than internasals. Frontal longer than its distance 

 from the tip of the snout, as long as parietals. Scales in 17 rows. 

 Ventrals slightly keeled on the sides, 155 or 165; anal entire; 

 subcaudals 45. Upper surfaces greyish brown, the borders of the 

 scales darker ; head with the ordinary symmetrical dark markings ; 

 the inner border of the seventh longitudinal series of scales, counted 

 on each side from the gastrosteges, darker, thus forming two fine 

 vertebral lines separated from each other by three rows of scales ; 

 belly yellowish, each ventral shield with a brown spot near the 

 lateral edge, these spots more or less confluent into a dark streak, 

 separated from the dorsal brown colour by a pure yellowish streak 

 of equal width ; in one of the two specimens the ventrals become 

 gradually entirely brown towards the posterior part of the body.
