HIPPOTHER1UM 



Two proximal phalanges which, from the differences in their proportions, 

 evidently belong one to the fore the other to the hind leg, are proportionately 

 heavier and more rugose than the corresponding bones of the horse, differing 

 in this respect entirely from the phalanx ascribed to H. gratitui. 



The measurements of these phalanges, the anterior of which is shown in 

 plate xix. fig. 8, are as follows : 



Length of anterior phalanx . .... 51 mm. 



Breadth at proximal end . . . . . . . 34 " 



Breadth at distal end 27 " 



Length of posterior phalanx . . . A . 56 " 



Breadth at proximal end . . . . \- 33 " 



Breadth at distal end . . . . . . . . 27 " 



The metapodials and phalanges of this species are proportionately longer 

 and more slender than the corresponding bones in H. occidentale.
