lunar facet by a contraction of the anterior and posterior borders. There 
is no indication of distinguishing ridge between the lunar and cuneiform 
facets. The posterior border at their junction is prominent, enclosing a 
fossa with the scaphoid condyle, which does not, however, excavate the 
intervening surface. The scaphoid condyle is not divided by a ridge. 
The ulna gradually contracts distally from a robust olecranon. The 
shaft beyond the humeral cotylus has an oval section, with its long axis 
forming an angle of 45° to the perpendicular. The olecranon is short and 
compressed, its posterior border rising nearly as high as the coronoid 
process. The edges of the humeral cotylus are not flared beyond the 
shaft. 
In the carpus the unciform nearly reaches the scaphoid, which is sup- 
ported by the magnum and trapezium, 
The great trochanter of the femur is not produced beyond the line of 
the head, and is well recurved, enclosing a large fossa. The little trochan- 
ter is large. The fossa ligamenti teris is submedian, subround and large. 
Distally, the patellar trochlear groove is quite elevated ; its lateral crests 
are of equal prominence, and nearly equal superior prolongation. The 
patellar groove is continued some distance above the crests, but there is 
no fossa in this region as in the hog. The popliteal fossa is well marked, 
and the condyloid articular surfaces are not entirely cut off from the 
rotular. The external linea aspera terminates first in a rugose muscular 
insertion, and then in a shallow fossa a short distance above the condyle, 
There is no crest nor deep fossa. This element is more like the corre- 
sponding one in Dicotyles torquatus than in any other mammal. The 
patella is a short wide bone, with a large anteroposterior diameter. One 
extremity is acute, the opposite one truncate. 
The head of the dédia is also like that of Dicotyles. The spine is divided 
as usual, and not much elevated ; the crest is prominent, but is wide and 
truncate above at the head. It is not excavated asin Sus. The external 
tendinous notch is well marked. The external margin of the shaft does 
‘not display any sutural surface for the fibula, he surface of attachment 
of an external malleolus is distinct. The internal malleolar process is nar- 
row and is produced well downwards. The anterior intertrochlear angle 
is prominent ; the posterior only convex. The trochlew are deep, the 
outer being both the wider and the deeper. 
The astragalus presents well marked characters. The distal extremity 
displays the two usual parallel trochles, which are separated by a pro- 
nounced angle. The cuboid trochlea slopes somewhat backwards, while 
the navicular is strongly concave. The tibial trochlew are unequal, the 
internal being smaller than the external. It is separated from the latter 
by a constriction which is well rounded and not angulate as in the hog. 
The external side of the astragalus displays a wide malleolar band, a wide 
posterior and narrow anterior calcaneal facets, and an undivided concavity 
intervening between the latter. On the inner side, the malleolar face
