Head small. A postnasal groove, entirely dividing the nasal ; 

 nasals forming a suture behind the rostral ; pnefrontals forming a 

 median suture ; frontal not twice as long as broad, a little longer 

 than the interparietal ; four supraoculars, second largest ; five or 

 six supraciliaries ; fourth upper labial entering the orbit ; anterior 

 nuchals passing gradually into the posterior. Ear-opening about as 

 large as the eye-opening, with two or three small triangular lobules. 

 Dorsal and caudal scales tricarinate, trispinose, the median spine 

 very strong ; dorsal scales largest, ventrals smallest ; 32 scales 

 round the middle of the body. The adpressed limbs overlap. 

 Digits short. Tail much shorter than the body, very strongly 

 depressed : the spines form eight longitudinal series, those of the 

 two outer series on each side much stronger than the others. 

 Olive above, with irregular dark brown cross bands ; lower surfaces 

 pale olive, with a few scattered dark dots.
