motive organs, deviate in another direction, and almost 
complete the transition from the Pachydermal to the 
Ruminant order. 
Among these genera the Dichobune of Cuvier is the most 
remarkable, inasmuch as the posterior molars (fig. 181, 7 1, 
m, 2, m, 3,) begin to exhibit a double series of cusps, of which 
the external present the crescentic form; and in one species 
(Dichob. murina, Cuv.,) the crescents are acute and com- 
pressed laterally, so that when viewed separately they 
might be mistaken for the teeth of a true Ruminant.* In 
the lower jaw of the Dichobune the penultimate and ante- 
penultimate grinders present two pairs of cusps, the last 
grinder three pairs, of which the posterior are small and 
almost blended together, so that when worn down they 
appear single. In this respect, as well as in the form of 
the ascending ramus of the lower jaw, Cuvier, who is not 
prone to exaggerated expressions, observes that the Dicho- 
bunes prodigiously resemble the young Musk-deer.+ 
This resemblance was well appreciated by Mr. Pratt, to 
whom we owe the discovery of the interesting extinct 
British quadruped which is the subject of the present 
section. The species, it is true, is represented by only a 
single fragment of the skeleton, but this is a characteristic 
one; it consists of the posterior half of the left ramus of 
the lower jaw with the three true molar teeth: it was 
found in the lowest bed of the freshwater marl at Bin- 
stead. 
* La position et le nombre des pointes y (Dichob.) sont les memes que dans 
Vespéce précédente; mais les pointes sont plus aigués et comprimécs latéralement, 
ce que tend encore dayantage 4 les rapprocher des molaires des Ruminans.—‘ Os-

+ Or cette dentition, cette forme de branche montante, cette grandeur méme, 
ressemblent prodigieusement a ce qu’on observe dans les jeunes Chevrotains,—
