Rhinoceros lemanensis (Pomel ! ). 

 Syn. Aceratherium lemanense, Pomel 2 . 



This species is usually of rather larger size than E. incisivus ; 

 and is distinguished by the slight development of the " crochet," 

 which is entirely wanting in half- worn teeth; there is a large 

 " antecrochet." The upper premolars and the lower cheek-teeth 

 have a strong cingulum ; and there is an incomplete one in the 

 upper true molars. A large Rhinoceros from the Quercy phosphorites 

 hap been provisionally identified by Filhol (Ann. Sci. Geol. vol. viii. 

 art. 1, p. 126) with R . incisivus (tetradactylus) ; but the specimens 

 io the Museum from the same deposits cannot be distinguished from 

 the present species a circumstance much more in harmony with 

 the respective geological age of the two species. 



Hob. France. 



29624. Cast of the left upper cheek-dentition, in a half- worn con- 

 dition. The original is from the Lower Miocene of the 

 Auvergne, France ; and is figured in De Blainville's 

 ' Osteographie,' genus Rhinoceros, pi. xii., as R. incisivus 

 d'Auvergne. The length of the series of seven cheek-teeth 

 is 0,260.
