A single individual, captured by Sir William Norris, differs from the 

 description given by M. M. Dumeril and Bibron in the comparatively 

 greater dimensions of the tail. It is strongly arched; its length 

 equals twice the breadth of the head ; it is covered with 16 trans- 

 versal series of scales, and it is considerably thicker than the rest 

 of the uniformly cylindrical body. The anterior frontal shield is 

 very broad, larger than the frontal. It was of the following dimen- 

 sions : — 



Length of the head, feet Of inch. 



Ditto ditto trunk, 1 Of 



Ditto ditto tail, Of 



1 ft. If inch. 

 Circumference of the trunk f inch ; of the tail f inch.
