ON BRITISH FOSSIL MAMMALIA. 295 
tion of the lateral surfaces for the attachment of the ligaments; the produc- 
tion of the inferior border of the distal articulation into a process for the 
insertion of the flexor tendon; and the greater curvature or portion of a 
circle described by the distal articular extremity, which indicates a greater 
extent and freedom of flexion and extension of the toe than the cold-blooded 
reptiles possess; all prove the fossil to have belonged to the more agile, 
warmer-blooded and higher organized Pachyderm. This fossil phalanx forms 
part of the collection of the Marchioness of Hastings. 
A fine fragment of the right ramus of the lower jaw, including the two 
posterior molar teeth, of a large Lophiodon, was dredged up from the bottom 
of the sea between St. Osyth and Harwich on the Essex coast. It is in the 
possession of Mr. Brown of Stanway. 
Genus Paleotherium. , 
Most of the British fossils referable to this genus have been obtained from 
the freshwater eocene marls at Binstead or Seafield in the Isle of Wight. I 
am indebted for the opportunity of determining the specimens here recorded 
from this locality to Mr. S. P. Pratt, F.R.S., and the Rev. Darwin Fox. 
They are as follows :— 
Paleotherium magnum . . . Antepenultimate molar, upperjaw. 
cots medium ... Posterior molar, lower jaw. 
eyes Do. ..... Portionofditto ditto. 
Basere Do. .... . Posterior molar, upper jaw. 
et es Do. .... . Penultimate molar, upper jaw. 
sesans Do. ..... Antepenultimate molar, upper jaw. 
chee Do. .... . Anterior spurious molar. 
fhe Do. ..... Crown of canine. 
panes Do. .... . Complete incisor. 
ests erassum ... Second molar, right side, lower jaw. 
“FE curtum (?). . A molar tooth. 
eases minus .... Portion of the base of the skull. 
“tae Do. ..... Right ramus of the lower jaw with six grinders. 
ia Do. ... .. Proximal end of the right radius. 
Cenren Do. ..... Shaft and distal end of right tibia. 
oh minimum .. Anterior molar tooth. 
A shaft and distal articular end of a humerus, black, heavy and completely 
mineralized, from the eocene clay at Hordwell Cliff, Hampshire, in the col- 
lection of Mr. Wickham Flower, belongs to the genus Paleotherium, and 
agrees in its size and proportions with the humerus of the Pal. crassum. 
Mr. Wickham Flower likewise possesses an inferior molar tooth of a species 
of Palezotherium, corresponding in size with the Pal. crassum, from the same 
stratum and locality. / 
Genus Anoplotherium. 
The remains of this genus have hitherto been met with in Great Britain 
only in the freshwater eocene deposits in the Isle of Wight, associated with 
quadrupeds of the same extinct genera as those with which the Anoplotherium 
was originally discovered by Cuvier in the eocene gypsum quarries at Mont- 
martre. The British fossils consist of molar teeth referable to the Anoplo- 
therium commune and A. secundarium. 
Genus Dichobunes. 
The most complete fossil referable to the Anoplotherioid family indicates a 
species of the subgenus Dichobunes, differing from those therein placed by 
Cuvier, and which I have named Dich. cervinum*. The fossil consists of the
