base continuous with the border of the heel, but none on the outer side. 
The antepenultimate molar has three cusps, of which the median is largest, 
and the anterior'and posterior have subequal bases. The anterior turns to 
the inner side of the tooth, the median stands on the outer side, while the 
posterior is median. It has an accessory tubercle on each side of it, that 
of the inner side much the more elevated, and combining with the median 
to form an incurved grinding-surface on attrition. This cusp sends a ridge 
downward and forward to the interior base of the crown, where it is suc¬ 
ceeded anteriorly by a rudimental cingulum. There is no external basal 
cingulum. The enamel bears marks of obsolete rugosities. 
Of bones of the limbs, there were found the distal end of the ulna, the 
shafts of both femora, and the distal third of the length of the tibia. The 
first-named piece is very characteristic. The articular face, although oblique, 
has nothing like the form seen in Ursiis, Canis, and Felis, since the external 
tuberosity is far less prominent, and its surface passes by a gentle slope into 
that of the inner part of the extremity. The radial facet is, on the other 
hand, presented inward and slightly forward, at a strong angle witli the .carpal 
surface The usual transverse fossa is present below, within the carpal 
extremity, while the superior surface is convex in transverse section, and is 
without well-marked tendinous grooves; The remarkable transverse extent 
of its carpal articulation has already been noted. The shafts of both femora 
are preserved, but the trochanters and condyles are wanting. The head 
displays the fossa for the ligamentum teres continuous with the deep 
emargination of the postero-internal border. The plate connecting it with 
the great trochanter is strongly emarginate, and the trochanter has an 
elevated position; the extremity is broken off. The shafts are compressed, 
the transverse diameter being the greater. The external border is the nar¬ 
rower, and, on the proximal regions, is produced into a low rib, which 
expands into the compressed tuberosity of the third trochanter. The base 
of the condyles shows that the internal condyle is the more elevated, and 
the external the more oblique. 
The shaft of the tibia is normally remarkably compressed at its distal 
third, so as to have an oval section, with the long diameter antero-posterior. 
The distal end has a remarkably produced malleolus, whose inner side, like
