appearance. Over each eye there is a rounded spot, placed 
slightly inwards towards the center of the head. 
A raised, vein-like fold of skin extends from behind each eye 
to the end of the body and is pale bronze in color. A stripe of 
similar color extends on each side of the head from the tip of the 
snout to behind the earplate, where it terminates in a raised 
skin fold. The under parts are white, indistinctly mottled with 
gray about the limbs.
