on the proximal phalanx is divided into two parts by a faint groove, which extends 
across the face and terminates in the deep plantar notch. On either side of the 
latter are facets on the extreme plantar angle of the proximal end which abuts 
against the sesamoids. The distal trochlea is, as in the manus, simply convex 
antero-posteriorly and concave transversely. The median phalanx is quite similar 
to that in the manus. The ungual phalanx is short, high, and somewhat com- 
pressed. They suggest strongly those of the recent camels though proportionally 
larger.

Sesamoids. — The sesamoids, though of considerable size, are much smaller than 
those of the manus. They are heaviest anteriorly and taper to an obtuse hook pos- 
teriorly. The dorso-proximal angle carries an articular surface which abuts against 
a corresponding surface on the proximo-plantar angle of the first phalanx described 
above.

The most conspicuous features of the skeleton of Dinohyus hollandi are the 
disproportionately large skull, the long muzzle, the heavy neck, the high withers, 
and the elongated limbs. Many other characters are impossible to fully appreci- 
ate without seeing the skeleton mounted in full relief. The thorax has nearly the 
same proportions as in Bos tawrus, but the lumbar region is shorter. In Sus the 
lumbar region is relatively longer than in Dinohyus, and the latter genus is, in this
