PETERSON: A REVISION OF THE ENTELODONTIDA 115 
that the scaphoid in the Miocene genus had a relatively greater transverse diam-

In 1908 the Carnegie Museum field party was fortunate in finding (see plan of 
the quarry, Pl. LIV, Sect. 19, No. 47) a fore foot which was almost completely

to our knowledge, inasmuch as the fore foot of the type specimen was found scat- 
tered, though in close proximity to the skeleton. 
The scaphoid as a whole has a small transverse diameter, while antero-posteri- 
orly it has the greatest diameter of all the carpal bones, which is due chiefly to the 
large palmar process. The more important characters in which this bone differs 
from that of Archwotheriwm, described by Professor Scott (87, pp. 8302-303), are the
