CERVINE ANOPLOTHERE. 443 
broader in the fossil, and that the last molar (i 8) has the 
third or hindmost tubercle distinctly divided by a middle lon- 
gitudinal fissure, which is not the case in the Moschus. The 
grinding surface is less oblique in the fossil than in the 
Musk-deer or any other Ruminant ; and the shape of the 
coronoid process differs in a still greater degree from 
that of the Moschus and other Ruminants, and by its 
superior breadth bespeaks the Pachydermal character of 
the fossil in question, 
These differences forbid its association in the same genus 
with the Musk-deer. On the other hand, we perceive, 
both in the structure of the teeth and the form of the jaw, 
a much closer resemblance between the Isle of Wight 
fossil in question and the genus Dichobune. But besides 
being somewhat larger than the Dich. leporinum, the 
ascending ramus of the lower jaw differs in form and 
approaches nearer to that of the true Anoplotherium. In 
this family (Anoplotheriide), however, Mr. Pratt’s inter- 
esting fossil indicates a new species, which I have referred 
to the genus Dichobune, under the name of Dichobune cer- 
ommum. 
In cut 181, the upper figure gives a view of the fossil 
from the outside; the lower figure a view from the inside, 
with an outline of the impression left by the jaw upon the 
matrix: to the right are given the grinding surface of the 
teeth.
