 length of one of them. Tongue with an obtuse papilla in the 

 middle. 



Habit very stout. Head large, much depressed, much broader 

 than long ; snout rounded, feebly projecting beyond the mouth, 

 as long as or slightly longer than the eye ; canthus rostralis obtuse ; 

 loreal region very oblique, feebly concave ; nostril nearer the
