lunar portion is concave, tlie scaphoid surface being oblique to it, and terminating 
at the end of the prominent styloid process of the radius. There is no radial 
cuneiform articulation. 
Ulna^ No. 10,013. — The ulna corresponding with the above radius is a long 
and slender bone. The olecranon tapers gradually ironi its base to the ajK'X which 
is expanded, flattened and strongly compressed laterally, forming a rather thin 
plate which separates the expanded distal portion from the base. The sigmoid 
cavity is deep and overhung by the prominent coronoid process. The distal i)art 
of the sigmoid cavity is wide, being limited at each side by j)i-ominent pnx-e.sses. In 
front of the sigmoid cavity the shaft has a deep fossa limited Ixdow by an obliciue 
ridge running across the radial surface of the bone. The shaft of the ulna is triang- 
ular in section, wuth its internal side concave, its radial face being obH«pie tt) the 
latter, and separated from the internal side by a prominent angidar ridge. The

distal part of the radial face is twisted upon the axis of the Ixme, so that this iH)r- 
tion of the face does not correspond with the upper part. As a result of this n)tu- 
tion of the distal extremity backward, the articulation of the ulna with the carpus is 
very different from that of the Tapir. Viewed from the fi-ont we obs<Tv.‘ 
in the manus of L. laticeps that the distal extremity of the ulna is placed far to 
the side and backward ; consequently the pisifonn is shut out fnnn forming a 
portion of the anterior face of the carpms, this being largely due to the shaiM. of 
the cuneiform, which is rectangular instead of being triangular as in the lapir.
