Forma typica. 



\'omerine teeth in strong or very strong, oblique, straight or 

 slightly curved series narrowly separated from each other, originat-

 process at the anterior extremity of the lower jaw in adult speci- 

 mens. 



Head as long as broad or broader than long, rather strongl}^ 

 depressed ; snout rounded or pointed, projecting more or less 

 bej'ond the mouth, longer than the eye; canthus rostralis obtuse; 

 loreal region ver}' oblique, more or less concave ; nostril equi- 

 distant from the eye and the tip of the snout or nearer the latter ; 

 interorbital space much narrower than the upper eyelid ; tym- 

 panum very distinct, f to once the diameter of the eye, i^ to 2^-
