Me. III and the smaller for Me. [V. In Daphenus the latter facets are divided in 
about the same proportions as in the present genus.

Unciform. —The facet for the cuneiform does not extend so far down on the 
ulnar angle as is the case in Daphanus, otherwise I cannot see any difference in the 
unciform in the two genera. On the dor- 
sal face the bone has a transverse exca- 
vation and lacks the heayy convex ru- 
gosity for muscular attachments seen in 
the tiger, nor is the palmar tuberosity so 
well developed ; otherwise the bones in 
the two forms are not greatly dissimilar. 
From Canis the unciform in Daphaenodon 
is at once distinguished by the lateral

position of the facet for the cuneiform, the 
the bones in the true dogs. The radial 
face is deeply excavated by a sulcus which corresponds to the one described on the 
ulnar face of the magnum. Around this sulcus is a large continuous, although ir- 
regularly shaped, facet for the magnum, which is altogether different from the four 
separated facets for the magnum in Canis. Immediately above the facet for the 
magnum there isa second facet, which articulates with the scapho-lunar. The ante- 
rior portion of this continues into the facet for the magnum in an imperceptible 
manner, while further back there is a decided ridge separating the two facets. Dis- 
tally the bone is entirely taken up by the large facets for Mc. IV and V.

Metacarpal I. —In their general characters the metacarpals are feline rather 
than canine. The first metacarpal is of approximately the actual length of that in 
an adult specimen of Canis lupus, but it is heavier, its proximal end is more expanded,
