13. COLUBRIDJE 



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.
