4. The dentition in the Maltese fossil Elephants, as shown by Dr. Falconer, 2 and 

 from materials collected by me in the Island of Malta, 3 furnishes a ridge formula in 



the Elephas Mnaidriensis as follows :

5. It is to be regretted that the dental series of Elephas Namadicus is not fully 

 ascertained, seeing the extremely close morphological resemblances between it and the 

 Elephas antiquus. As far as the few instances of lower teeth afford materials for 

 comparison, we have :

It will be observed that the highest expression of the ultimate molar of E. Meri- 



1 Blainville, as pointed out by Falconer, makes the second milk hold seven, and the third milk molar 

 six ridges, which is at variance with the rules which have hitherto regulated the dental succession in the 

 genus, ' Pal. Mem.,' vol. ii, p. 89. The dentition of E. Africanus is still far from being accurately 

 determined.
