From comparison of a number of living individuals it appears that 

 the deeper or lighter greenish colour of the back, and the absence or 

 presence of vertical lines on the sides are but individual differences, per- 

 haps influenced by age, sex, or habits. Buchanan Hamilton correctly 

 observes " there are very minute scales on the body and upper part of 

 the head." They are imbedded in the skin, distant, orbicular or 

 slightly oval, and become larger towards the tail. On submitting a 

 portion of the skin to 60 or 100 linear magnifying power, the scales 

 may be seen distinctly enough. This species is very numerous 

 at Pinang.
