Manus. — The manus is represented by a number of metacarpals of both sides, 
the unciform and trapezoid of the right foot and a phalanx ; the latter may equally 
well belong to the hind foot. 
The unciform is of very nearly the same proportionate height, but of less trans- 
verse diameter than in Meles tawus; the facet for the cuneiform descends on the ulnar 
side to about the same extent as in the recent form, while the facet for the scapho-

lunar occupies a liberal portion of the radial angle. The facet for the magnum is 
continuous from the distal to the proximal face, as in Daphanus and Daphenodon, 
but the lunar facet is more distinctly separated from the facet for the magnum than 
in the latter genera. This is due to a prominent sinuous ridge, which extends from 
the dorsal border, obliquely upward and backward so that the upper portion of the 
facet for the magnum is concave supero-inferiorly, while the lower portion is plane 
antero-posteriorly ; the facet for Me. III near the distal face is convex antero-pos- 
teriorly. The palmar tuberosity is compressed transversely ; it is more prominent 
than in Meles taxus or the recent otter, but does not extend so high up upon the 
palmar face as in Daphanus or Daphenodon. Distally the bone is much expanded 
and the articulations for Mc. IV and V are transversely broad and concave in the 
antero-posterior direction. 
The trapezoid is quite depressed and triangular in outline. Its proximal face
