20 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [June 16, 
register provisionally the Hordle fossils here described under the 
name of Paleotherium medium. 
Grinding surface of lower molars. Paleotherium medium ? 
Part I.—Description of Lower Molar Teeth from Hordle, indica- 
tive of a distinct generic form in the Paleotherioid family. 
Some fragments of inferior molar teeth of a smaller Palzeotherioid, 
among which was an entire crown (figs. 5 & 6), proved most decidedly 
the former existence of a species of this family of Pachyderms in the 
Hordle deposits, distinct from any of those previously recorded by 
Cuvier or other authors. 
Lower molar. Paloplotherium. 
The two semicylindrical lobes 0, o', were less angular than im the 
preceding species of true Paleothere from Hordle; but the basal 
ridge was absent from the inner side of the crown (fig. 6), and 
was reduced at the outer side (fig. 5, 7) to a rismg at the bottom 
of the median fissure, and to two terminal and very oblique ridges, 
the posterior of which ended by forming a distinct tubercle (¢) behind 
the hinder semicylindrical lobe (0’). 
These characters indicated something more than a distinct species 
of Paleotherium. But as other and more decisive characters of its 
generic distinction were afforded by more complete specimens of jaws 
and teeth of the same species from the same formation and locality, 
subsequently transmitted to me by the Marchioness of Hastings and 
Mr. Falconer, I shall proceed to the description of these specimens 
without further dwelling upon the earlier and more fragmentary 
evidences. 
Part Il1.—Description of the Lower Jaw with the deciduous and 
permanent Teeth of a new genus of Paleotherioid, for which the 
name of Paloplotherium zs proposed. 
(Pl. IIT. figs. 3 and 4.) 
Aw almost entire lower jaw (PI. III. figs. 3 & 4) obtained from Hordle 
Cliff, and kindly transmitted to me by Alex. Pytts Falconer, Esq., 
has an uninterrupted series of six entire grinding teeth on each side, se-
