of the orange bars across the body of the young; below, bluish 

 yellow. In a large adult (275 millimeters long) the color is 

 olive brown above with a series of 6 lateral bars of ocellated 

 scales, widely separated from their fellows dorsally. Traces of 

 annulations are visible on the tail ; bluish beneath. Other speci- 

 mens agree in markings and coloration with these according to 

 their ages. 



Specimens of this species were collected from the tops of large 

 felled trees. It is a retiring species and is never observed on the 

 ground.
