Fig. 2. — E. Ganesa. Palate view of same skull. The right in- 

 cisive is seen in section. The posterior true molar is seen on either 

 side of palate. It has ten plates and a heel behind, and a small talon 

 in front ; the hind heel has few denticles ; the four front ridges are 

 worn. The alveoli are parallel as in the Mammoth. — B.M.
