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 : 



" FOSSIL 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.Gr.S. It is the left ramus of a 

 young, but nearly full-grown individual of the Rhinoceros 

 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 cubitus to the ' espece cloisonnee ; ' 

 and again, with regard to the ' os innominatum, 1 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
