Head rather elongate; body moderately elongate; limbs well 
developed. Frontonasal quadrangular, longer than broad ; frontal 
trapezoid, anteriorly as broad as the frontonasal; frontoparietals 
forming a long suture; parietals rather small; interparietal nearly 
as large, hexagonal, narrower anteriorly; a pair of occipitals; four 
supraoculars ; a loreal ; a row of large infraorbitals ; temple shielded; 
six upper labials, posterior largest; five lower labials; chin-shields, 
one anterior and four pairs, the two first pairs forming a suture; 
these are followed by large, irregular hexagonal gulars; the other 
gulars quadrangular, increasing in size towards the collar-shields, 
which are largest and eight in number; seven transverse rows of 
quadrangular gulars, including collar. Dorsal scales quadrangular, 
keeled, about twice and a half ag long as broad ; lateral scales much 
smaller, half as long, also quadrangular and keeled; forty-one 
scales round the middle of the body, including ventrals; thirty-five 
scales from occiput to base of tail. Ventrals large, quadrangular, 
smooth, forming ten or twelve longitudinal and twenty transverse 
series. Preeanals seven, an anterior pair and five shields in the 
posterior row. Limbs with large smooth shields; tibia above 
with keeled scales; lower surface of arm and hinder side of thighs
