Coryphodon No. III. 
Plate Ixi. 
The specimen referred to under this head was found at the same time 
and at the locality which furnished the Coryphodon molestiis. It represents 
a different individual, and of smaller size than those previously described. 
The bones are moreover characterized by their black color, Avhich, while 
not conclusive as an index of identity (or pertinence) to one individual, 
indicate a similarity of situation, which adds to the probability that such 
is the case. The bones are supposed clavicles, nearly all the elements of a 
right fore foot, broken scapulae and femur, and three tarsal bones. 
The clavicles are the only ones obtained in any species of Coryphodon. 
Each one is rather slender and slightly curved. The shaft is compressed, 
with one edge narrower, so as to give an ovoid section. The extremities 
are considerably enlarged into subglobular masses, with oval cross-secfion 
and truncate ends. Neither clavicle is preserved entire. The fore foot is 
represented by all the carpals, with the trapezium fortunately attached to 
the first metacarpal, and all the metacarpals with the pollex and third digit 
complete with other phalanges. The carpals present no peculiarities as 
compared with those of other species, excepting that the exposed anterior 
face of the magnum is more transverse. The digits display no marked 
peculiarities. The fifth metacarpal is about two-thirds as long as the third, 
which is nearly twice as long as the first. The basal facet of the first 
metacarpus is squarely truncate; the first phalange is relatively a little 
longer than the corresponding one of the other digits, and the ungual phalange 
is also a little longer; the entire pollex is turned outward, the inner side of 
the two phalanges being a little longer than the outer, the entire digit being 
two-thirds as long as the third, which is a little longer than the second. 
Of the hind foot^ only the calcaneum, astragalus, and navicular remain, 
of which the first two exhibit some peculiarities. The calcaneum is L- 
shaped, but the transverse anterior portion is shorter than the long axis of 
the bone. The posterior free portion is moreover not depressed, as in Nos. 
I and II, but is compressed, altliough short and swollen at the extremity. 
There is no horizontal surface on the external side for the extremity of the 
fibula. The astragalus is generally like those already described, but is
