The lateral scales which fall within the dark blotches 
often have light centers, while those in the light intervals 
are similarly spotted with black or brown. Small black or 
brown blotches are sometimes present on the sides midway 
between the larger ones. The lower surfaces are yellow 
or white, unicolor or marbled with black or brown.
