318 RHINOCEROS. 



Cuvier and of Owen. He admits the partial bony septum 

 described by the latter, and even concedes three fossettes to 

 the upper molars, as in Rhin. tichorhinus, excepting only the 

 last true molar ; while he attributes to it the slender pro- 

 portions inferred by Cuvier, and assigns for its habitat Italy 

 and the Pliocene formations of England. Laurillard ad- 

 mitted also Rhin. megarhinus of Christol, or Rhin. Mons- 

 pessulanus of De Blainville, as a distinct species. He refused 

 to accept the Rhin. Merckii of Jager and Kaup, and the 

 Rhin. elatus of Croizet he regarded as referable either to 

 Rhin. megarhinus or to Rhin. leptorhinus. 



Gervais has devoted much study to the fossil species of 

 Rhinoceros, occurring in the Pliocene and Post-Pliocene de- 

 posits of Auvergue and the South of France. The results 

 are embodied in the ' Paleontologie Pran9aise.' He adopts 

 the Rhin. megarhinus of Christol, yet although that species is 

 described by all original observers, himself inclusive, as 

 devoid of a bony septum, he considers it probable that the 

 Clacton cranium figured by Professor Owen as of Rhin. 

 leptorhinus belongs, notwithstanding its septum, to that 

 form. On the other hand, he doubtingly admits the Rhin. 

 leptorhinus of Cuvier as a distinct species, occurring in Italy 

 and the Yelay. He has applied the designation of Rhin. 

 Lunellensis to the remains of a species discovered in the 

 Cave of Lunel-viel, first named Rhin. minutus by Marcel de 

 Serres, Dubrueil, and Jean-jean, under a mistaken interpre- 

 tation of the age of the teeth, and at a later date described 

 as being identical with the Rhin. Africanus. He has re- 

 peatedly directed the attention of palaeontologists to the 

 important fact, that this fossil species of Lunel-viel is hardly, 

 if at all, distinguishable from the existing two-horned Rhi- 

 noceros of the Cape. 



Pomel, in his ' Catalogue,' published in 1854, after a study 

 of the remains occurring in Auvergne and the Velay, admits 

 Rhin. leptorhinus with a bony nasal septum, as defined by 

 Professor Owen, but under the designation of Atelodus lep- 

 torhinus ; and gives for its habitat England, the Milanese, 

 and the valley of the Rhine. Under another name, Atelodus 

 elatus, he includes the Rhin. elahis of Croizet, and the Rhin. 

 megarhinus of Christol. A third species, exclusive of Rhin. 

 tichorhinus, he designates Atelodus Aymardi, and refers to it, 

 as a synonym, the Rhin. leptorhinus of Gervais. 



Duvernoy, the successor of Cuvier and De Blainville in the 

 chair of Comparative Anatomy, attempted a revision of the 

 Eossil Species of Rhinoceros, in a very elaborate memoir 

 published in 1854. In the section devoted to the Pliocene 

 species, he maintains, with many details, that the Rhin.
