American form. Schizotheriwm priscum is represented by the casts of a proximal 
and a terminal phalanx in the Carnegie Museum. The proximal phalanx is quite 
similar to that of Moropus, while the terminal is relatively broader, shorter, more 
widely cleft, and it undoubtedly carried a proportionally broader hoof than was 
found in the later forms.

(Plates LVIII-LX; LXX-LXXI.) 
The pelvic girdle has already been fully described (see pp. 320-323), in con- 
nection with the sacrum. It is therefore not necessary to more than refer to this 
part of the work in this connection. 
The Femur. 
(Plate LXX.) 
The general outlines of the femur recall the same bone in Titanotherium. 
In proportion to the tibia it is, however, shorter, the head is less raised, the tro-
