ARSINOITIIEIUUM. 
Gi 
The other specimen (1 a, 1b) seems to bo a lateral metatarsal. It is shorter ami 
stouter than the last, and is distinctly convex towards the median axis of the foot. 
Its proximal surface is convex from before backwards and slightly concave from side 
to side. Posteriorly it is produced backwards into a pair of blunt tuberosities. The 
outer face is occupied by swollen roughened ridges. The distal articulation is similar 
to that described on the other metatarsal, except that the posterior surface is distinctly 
bilobate and no doubt bore a pair of sesamoids. 
T\\q phalanges are unknown. 
Text-fig. 37. 
Pelvis and hind limbs of Arsinoitherium zitteli. 
The first and second metacarpals and the phalanges are restored, nat. size. 
From the large mass of material in London and Cairo it has been possible to 
attempt a restoration of the entire skeleton, and the result is shown in text-fig. 36. 
The chief parts of the skeleton remaining incompletely known are the sternum, ribs, 
posterior caudals, and the phalanges ; these are distinguished in the figure by 
being left without shading. With these exceptions it is probable that the figure 
gives a fairly accurate idea of the general form and proportions of the whole skeleton
