species the " splint-bones " did not unite with the third metapodial. 

 The specimens in the Museum indicate a great variation in size ; 

 those from the Pleistocene of Essex and Kent belonging to a very 

 large race, while those from the Brighton " elephant-bed " are equally 

 small, and some of the latter may perhaps belong to E. hemionus. 

 Variations in the form of the proximal articular surface of the third 

 .metatarsal are noticeable in some instances. 



In the typical form the long diameter of the anterior " pillar " of 

 the upper cheek-teeth is equal to more than one third the length of 

 the crown ; the crowns are nearly straight and square ; the enamel- 

 plications are usually not very complex, there is no maxillary fossa, 

 and the maxilla is produced much behind m. 3.
