than the rest, which pass over each eye ; a sort of 

 ridge or prominent edge being continued from 

 those parts as in the Chameleon, towards the back 

 of the head, where they unite, and are continued 

 in form of a short denticulated crest, down the 

 middle of the back to the beginning of the tail, 

 which is much longer than the body. The body 

 is covered with moderately small acuminated

 or mottled with a few variegations of a still deeper 

 cast. It is a native of the island of Cevlon.
