HIPPOPOTAMUS. 35 



V. CONCLUSION. 



In the present memoir no new material relating to the origin of the Hippo- 

 potamidce is brought forward, and such new records as the memoir contains do not 

 materially extend the known area of the distribution of the hippopotamus in 

 Britain. The author agrees with Boyd Dawkins, Lydekker and others in 

 regarding the Hippopotamus major of the Pleistocene as inseparable from H. 

 amphibius. Evidence that the missing incisor tooth of //. amphibius is the third is 

 brought forward.
