is contained about once and a fourth in the distance between 

 axilla and groin. Snout rather short, obtusely pointed. 

 Lower eyelid scaly. Nostril pierced in a single nasal, no 

 supranasals; frontonasal much broader than long, forming 

 a narrow suture with the rostral ; praefrontals generally 

 forming a median suture (in one of our three specimens 

 a small triangular scale, separated from the frontal, wedges 

 itself in between the two frontonasals) ; frontal somewhat 

 shorter than interparietal and frontoparietals together, its 

 posterior part very narrowly pointed, in contact with two 

 supraoculars; four supraoculars; nine supraciliaries ; fronto- 

 parietals and interparietal distinct, subequal in length ; 

 parietals forming a suture behind the iuterparietal ; no 

 enlarged nuchals, but each of the parietals bordered by four 

 scales of which the fourth (anterior) is very large. Ear- 

 opening roundish, smaller than the eye-opening, without 

 auricular lobes. Third to fifth upperlabial below, but not 

 in contact with the eye. 24 rows of smooth scales round 

 the middle of the body, dorsals largest. A pair of enlarged 

 praeanal scales. The length of the hind limb a little larger 

 than the distance between the tip of the snout and the 

 fore limb. 22 smooth subdigital lamellae under the 

 fourth toe ; the adpressed limbs overlap. Tail thick, once 

 and a fourth to once and a fifth as long as head and 

 body. 



Above reddish brown, with four longitudinal rows of 

 darker spots, two on the middle of the back and one on 

 each side, beginning behind the eye; lower parts uniformly 

 light coloured. 



Length from the tip of the a be 



snout to the fore limb: 37 mm. 34mm. 32mm. 



Length of the tail: broken. 42mm. 39mm.
