 length of snout, 3J iu head ; eye half interorbital width, 5 in head. 



Teeth iu lower jaw pointed, in a single close-set series, their even tips 

 forming an almost uuiforni cutting edge. Teeth iu upper jaw ap 

 pareutly paved, the jaw presenting a smooth, rounded surface, on 

 which the teeth are little evident, but occasionally present sharp pro- 

 jecting points. Lower jaw included.
