Snout short, ohtiise : cheeks strongly swollen in full-grown speci- 

 mens. Nasal small, followed by a small postnasal which forms a 

 suture with the first labial ; anterior loreal forming a suture with 

 the frontonasal ; four supraoculars, the three anterior in contact 

 with the frontal ; posterior border of the interparietal in contact 

 with the nuchals, of which there are one or two pairs ; seventh or 

 eighth upper labial the largest ; ear-opening about as large as a 

 dorsal scale, with two or three more or less distinct obtuse lobules ; 

 two azygos postmen tals. 28 to 32 scales round the body, subequal, 

 the laterals but little smaller than the dorsals and ventrals. The 

 length of the hind limb is contained twice and one fourth to twice 

 and a half in the distance from snout to vent ; when pressed 

 against the body, the limbs overlap. A median series of trans- 

 versely enlarged subcaudals. Young blackish above, with five 

 longitudinal whitish lines, the median bifurcating on the occi- 

 put ; tail bluish. In the adult these markings become more indis- 

 tinct or entirely disappear, the body turns to brown, and the 

 head is often red. Lower surfaces yellowish white, belly sometimes 

 greyish.
