RHINOCEROS TICHORHINUS. 343 



aged animal. The upper incisors appear to be earlier lost ; 

 and the traces of those below are generally obliterated in 

 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 vertebra?. 



Portions of two caudal vertebrae. 



Portions of four ribs. 



The symphysial end of an os pubis. 



Portions of the right and left scapulee. 



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. 



Both articular extremities of the right femur. 



Part of both extremities of the left femur. 



The left patella.
