slants excessively downward in the ulnar direction, meeting the facet for Mc. II at 
an acute angle, so as to form a prominent and sharp ridge, which extends a short 
distance from the dorsal face backward almost identical with that in Meles and 
Iutra. Back of this ridge on the ulnar face is a rugose area for muscular attach- 
ments, the bone terminating palmarly in a round obtuse point. Distally the sur- 
face for Mc. II is convex transversely, the radial side less strongly than the ulnar, 
while antero-posteriorly the articulation is very slightly concave. The radial face 
is taken up almost entirely by the large facet for the trapezium. The latter is 
undoubtedly of large size judging from the large facets on the trapezoid and on 
Merl, 
The first metacarpal is rather short when compared with that of Gulo, or even 
with that of the recent badger, and is more like that in the otter; it is also proportion- 
ally shorter than that in Megalictis ferox Matthew from the lower Miocene of South 
Dakota. The proportionate length of the metacarpals as a whole agree quite closely, 
however, with those in the latter genus. The facet for the trapezium is, as stated, 
of large size, and it is obliquely convex antero-posteriorly, extending well down on 
the shaft as in Meles, and is not unlike that of Megalictis ferocMatthew and diluro- 
cyon brevifacies Peterson.” The shaft has received some injury in the process of col- 
lecting, but enough is preserved to show that it was heavy, well arched forward, 
and quite cylindrical. The distal trochlea is fully developed and carried the usual 
two phalanges. 
The second metacarpal is quite heavy and in its general proportion it compares 
well with that in Megalictis. The head rises above that on Me. III, so that the 
ulnar face has a facet for the magnum similar to that in Meles, while in Megalictis 
the head is apparently raised higher (see illustration, fig. 15, of Dr. Matthew’s paper, 
i. ¢.). The facet for the trapezoid is concave transversely, the ulnar angle being 
higher than the radial. The palmar tuberosity is a hemispherical knob, while 
radially the head has an uneven surface for muscular attachment. On Me. II of 
the right side there is no articular facet for Mc. I, while the one on the left side 
has a small facet near the dorsal angle. The origin of this facet may, in part, 
be due to injury received in this region, which is plainly shown by the rough 
surface of the proximal portion of the bone. The shaft is very heavy, slightly 
arched forward, and transversely oval in cross-section. The dorsal portion of the 
trochlea is not nearly as hemispherical as in Daphawnus, while plantarly it is divided 
by a prominent carina, the radial portion occupying a higher position than the 
ulnar, causing asymmetry of the trochlea.
