cially oil the outer or ulnar side, giving a very similar shape to that seen in the large 
cats. 
The carpus is entirely creodont in character, and differs from that of any known 
carnivore in the presence of a central and the separation of the scaphoid and lunar. 
The scaphoid has a very small vertical diameter ; its proximal surface shows an inner 
concave surface and an outer convexity; the distal facets meet at a low angle. The 
lunar is narrower but of greater height than the scaphoid, and the radial surface 
comes far down on the anterior face ; it has not the regular wedge-shape seen in 
Memnyx, but shows an infero-lateral surface for the central, a verj’ small inferior face 
for the magnum and a still smaller one for the unciform. The cuneiform is a large, 
square bone; on the external side it gives off a strong recurved hook-like process; the 
ulnar and unciform facets are both concave. The pisiform is very large and is espe- 
cially expanded at the free end. The trapezium is of very unusual size ; it descends 
below the level of the trapezoid and abuts against the radial side of the second meta- 
carpal. The trapezoid is smaller; it has little contact wdth the scaphoid, being 
almost completely separated from it by the central; its metacarpal facet is saddle- 
shaiMxl. The central has a more internal position than va. Mesonyx, being wedged in 
between the scaphoid and trapezoid and touching the magnum and lunar by small 
^surfaces; it is wedge-shaped, with the edge placed anteriorly ; posteriorly it thickens 
rapidly. The magnum is missing from the specimen, but from the relations of the 
surrounding parts it was obviously small. The unciform is large and has a sub- 
quadrate anterior face ; nearly all the proximal surface is covered by the cuneiform, 
leaving a ver>’ small facet for the lunar; the surfaces for the fourth and fifth meta- 
carpals are plainly marked; the latter is altogether distal and does not extend on the 
external side. 
-\s a whole, the carpus is very low and broad. (See PI. VU, Fig. ,5). 
The mciacarpah are five in number, and, as in Mesomjx, show’ a greater degree of 
interlockmg than in any carnivores except the cats. In order of length they are III, 
1 ' , 11, \ ,1. No. I is quite short, but stout, especially proximally, and fits into the 
tm,Hv.ium by a convex head. No. II is the stoutest of the series; on the radial side 
of the proximal end it has a facet for the trapezium; the ulnar side is somewhat ex- 
ca^ated for No. II, and sends out a strong process, which abuts against the magnum.
