 with an enormous, erect, sharp bony ridge from the orbit to the 

 parotoid, in the adult ; this ridge scarcely developed in the young ; 

 a more or less distinct parietal ridge ; snout prominent, pointed ; 

 interorbital space much broader than the upper eyelid ; tympanum 

 more or less distinct, about two thirds the width of the eye. First

 beyond. Skin covered with small warts ; parotoids rather small, 

 subtriangular, oblique ; a lateral fold formed by a series of large 

 conical warts. Brown above, with a few black spots ; frequently a
