RHINOCEROS TICHORHINUS. 343 
aged animal. The upper incisors appear to be earlier lost ; 
and the traces of those below are generally obliterated im 
specimens of Rhinoceros tichorhinus with the molar series 
complete. 
The characters of other enduring parts of this species, 
as defined by Cuvier, have been satisfactorily confirmed, 
not only by the discovery of the almost entire skeleton 
of the same individual tichorhine Rhinoceros, in the Cave 
at Wirksworth, but by other not less extraordinary and 
instructive instances. 
In 1816 a considerable portion of the skeleton of a Rhi- 
noceros was discovered by Mr. Whidbey, engineer of the 
Plymouth Breakwater, in one of the cavernous fissures of 
the limestone quarries at Oreston, near Plymouth: the 
following parts, most of which were determined by Mr. 
Clift, were recovered and preserved :— 
Two molar teeth of the upper jaw. 
Four do. do. lower jaw. 
Portion of the first vertebra, atlas. 
Portions of four dorsal vertebree. 
Portions of two caudal vertebree. 
Portions of four ribs. 
The symphysial end of an os pubis. 
Portions of the right and left scapule. 
Both articular extremities of the left humerus. 
Do. do. right ulna. 
Do. do. left radius. 
The right os unciforme. 
The middle metacarpal bone of the right fore-foot. 
A phalanx of the same toe.
