RHINOCEROS TICHORHINUS. 347 
eastern coast, have yielded very fine remains of more than 
one extinct species of Rhinoceros. 
The Cambridge Advertiser, for the 26th of February, 
1845, contains the following announcement :— 
“ Fossin REMAINS; Cromer.—The late high tides have 
partly uncovered the lignite beds along the base of the 
cliffs, and among the fossil remains of that stratum have 
been found a fine specimen of the lower jaw of a Rhino- 
ceros, with the seven molar teeth in good preservation ; 
together with molars of the Elephant, Hippopotamus, and 
Beaver.” 
The jaw of the Rhinoceros has been obligingly trans- 
mitted to me for examination by its present possessor, 
Robert Fitch, Esq., F.G.S. It is the left ramus of a 
young, but nearly full-grown individual of the Lhinoceros 
tichorhinus. The socket of the first small premolar is not 
obliterated ; the second and third premolars, the last deci- 
duous molar, and the first and second true molars, are in 
place: the crown of the last true molar is just about to 
emerge from its alveolus; the last premolar is concealed 
in the substance of the jaw, beneath the third much worn 
tooth in place. This interesting specimen, which exem- 
plifies one of the later stages of the dental changes of the 
extinct Rhinoceros, will be again adverted to in compa- 
rison with a corresponding fossil of the Rhinoceros lep- 
torhinus. 
With regard to the most instructive remains of the Rhi- 
noceros from Lawford near Rugby, Cuvier (loc. cit. p. 
80) expressly refers the cnbitus to the ‘ espece cloisonnée ;’ 
and again, with regard to the ‘os immominatum, he says, 
that it seems to belong to the species with the osseous 
septum, viz. the Rhinoceros tichorhinus: in reference 
to the tibia and the cervical vertebrae, Cuvier confines his
