Pattern none, except yellowish patches surrounding the cornicular base and two

Cornicles long and slender, of the colour of the body, but nearer the tip black ; 
only slightly swollen in their distal one-third and on one side towards the middle line 
of the body ; they reach to about the termination of the cauda. Scaly throughout. 
Cauda broad conical, often reflected over the base; distal half beset with teeth, 
dusky ; base broader, edged with black but greenish transparent and without teeth ;
