 as long as frontoparietals and parietals together, in contact with the 

 three anterior supraoculars ; four supraoculars ; eight supraciliaries, 

 first and last largest ; frontoparietals and interparietal distinct, 

 equal in length : parietals forming a suture behind the interparietal ; 

 a pair of irregular nuchals ; sixth and seventh upper labials below 

 the ej'e. Ear-opening suboval, much smaller than the eye-opening,

Habit lacertiform, limbs rather short; the distance between the 

 end of the snout and the fore limb is contained once and one fourth 

 to once and two fifths in the distance between axilla and groin. 

 Snout short, obtuse. Lower eyelid scaly. Nostril pierced in a single 

 nasal ; no supranasal ; frontonasal broader than long, forming a 

 narrow suture with the rostral and with the frontal ; latter as long 

 as frontoparietals and parietals together, in contact with the two or 

 three anterior supraoculars ; four supraoculars ; nine or ten supra- 

 ciliaries ; frontoparietals and interparietal distinct, equal in length, 

 or latter shorter than former ; parietals forming a suture behind the 

 interparietal ; three enlarged scales on each side border the parietals ; 

 sometimes three pairs of nuchals ; sixth and seventh, or sixth to 

 eighth, upper labials below the eye. Ear-opening suboval, much 

 smaller than the eye-opening ; no auricular lobules. 32 or 34 

 smooth scales round the middle of the body ; laterals smallest. A 

 pair of large prseanals. The adpressed limbs meet, nearly meet, or 

 overlap. Digits rather short, slightly compressed ; subdigital 

 lamellae tubercularly keeled, divided, 20 to 23 under the fourth toe. 

 Tail very thick, a little longer than head and body ; upper caudal 

 scales obtusely keeled, the keels forming continuous lines. Pale 

 brown above, with rather irregular narrow dark brown cross bands, 

 ometimes interrupted, obliquely descending forwards on the sides :
