 in lower jaw, these projecting anteriorly near symphysis, a few 

 flaring outward and curving somewhat posteriorly at sides of sym- 

 physis ; inner teeth minute, few in number and in a single row in upper 

 jaw, forming small patches of very minute teeth on either side of 

 symphysis in lower jaw; snout scaled to tip, hne from eye, including
