longed to the Pachydermata and was most nearly allied to the Pec- 
cari. In some points, however, in which these remains deviate from 
the Peccari, they were shown by Mr. Owen to indicate an approach 
to the carnivorous type, and this affinity he showed is further exhi- 
bited in the specimen found by Mr. Fox, in the prolongation back- 
ward of the angle of the jaw, a character which in the class Mam- 
malia has hitherto been found almost exclusively in the carnivorous 
order, and certainly in no pachydermatous or other ungulate species 
of Mammal. In the jaw from the Isle of Wight the angle is more 
compressed and deeper than in the bear, dog, or cat tribe; and it is 
not bent inwards in the way which peculiarly distinguishes the mar- 
supial jaws, and which so neatly characterizes the Stonesfield mam- 
miferous remains. The condyloid process in the Cheropotamus is 
raised higher above the angle of the jaw than in the true Carnivora; 
and it is less convex than in the hog or peccari; and the coronoid 
process is more developed than in the peccari. In the wavy out- 
line of the inferior border of the lower jaw, and in the teeth, which 
are well developed in the jaw described by Mr. Owen, a close re- 
semblance is displayed in the Cheropotamus to the peccari. The 
jaw contains three true tuberculated molars and three conical false 
molars with double fangs, which molars are relatively larger than 
in existing Suid, and an anterior tooth, which Cuvier in the Paris 
basin specimens considered to be a canine, but which is situated 
closer to the symphysis of the jaw than in any of the Suide. 
Mr. Owen then observed, that the occasional canine propensities 
of the common hog are well known; and that they correspond with 
the organization of the genus which offers the nearest resemblance 
among the existing Pachydermata to the carnivorous type of struc- 
ture. In the extinct Cheropotamus we have evidently another of 
those beautiful examples in paleontology of links tending to com- 
plete a chain of affinities which the revolutions of the earth’s sur. 
face has interrupted, and for a time concealed from our view. It is 
interesting also to perceive that the living subgenus of the hog tribe 
which most resembles the Chxeropotamus should be confined to the 
South American continent, where the Tapir, the nearest living ana- 
logue of the Anoplotherian and Paleeotherian associates of the Che- 
ropotamus, how exists. 
The author then offered some remarks on a jaw discovered by 
Mr. Pratt in the Binstead quarries in 1830, and considered by him 
to be allied to the genus Moschus*. On comparing the jaw with 
‘the corresponding part of the Moschus moschiferus, which it resem- 
bles in size, Mr. Owen has found that in the fossil the grinders are 
relatively broader, that the last molar has the third or posterior tu- 
bercle divided by a longitudinal fissure, that the grinding surface is 
less oblique, and that the coronoid process differs from that of the 
Moschus and other ruminants, but strongly bespeaks an affinity with 
the Pachydermata.
