THE OSTEOLOGY OF ELOTHERIUM. 319 
The phalanges of the pes differ from those of the manus principally in their greater 
slenderness. The first phalanx is a little longer than that of the fore-foot, and decidedly 
more slender ; the proximal trochlea is less deeply concave and the groove for the carina 
narrower and deeper. The second phalanx is of nearly the same length as in the fore- 
foot, but is much narrower and somewhat less asymmetrical in form. As Kowaleysky 
points out, the proportions of this phalanx are very exceptional among ungulates. The 
ungual is smaller in every dimension than that of the manus and, in particular, is nar- 
rower. Apparently, Anthracotherium (Kowaleysky, ’73, Taf. XI, Figs. 52, 53) displays 
the same difference between the phalanges of the pes and those of the manus as does 
Elotherium. In Sus and Hippopotamus the phalanges of the two extremities differ very 
little.
