 extending along the whole length of the thighs and forming an 

 angle in front of the praeanal region. Tail slender, round, de- 

 pressed at the base, twice and a half as long as head and body ; 

 caudal scales equal, strongly keeled. Grey above ; with a longi- 

 tudinal white band on each side from the neck to the base of the

Differs from the preceding as follows : — Nostril pierced in the can- 

 thus rostralis, directed more upwards than sidewards. Dorsal scales 

 increasing strongly in size towards the vertebral line and the posterior 

 part of the trunk, where they are as large as those on the outer 

 side of the limbs or on the tail. A low nuchal crest. Only twenty- 

 two femoral and praeanal pores. Yellowish brown above, with 

 black spots and dots which on the sides of the neck and body are 

 confluent into two or three longitudinal lines, and white spots con- 

 fluent into transverse bands ; tail with alternate broad brown and 

 narrow white cross bars, and a median white longitudinal line ; 

 throat with bluish-black network.
