POMEL ON THE PALEONTOLOGY OF AUVERGNE. 63 



in Auvergne. The Hyenas of Perrier, one of which also occurs in 

 Tuscany, are quite distinct from those of St. Privat and Tormeil, 

 which last are identical with the cavern species. The remarkable 

 subgenus of Felis named Stenodon is peculiar to the Pliocene de- 

 posits ; and the other Feles cannot be confounded with the more re- 

 cent species of La Tour de Boulade and of Coudes. 



The Pachyderms and Ruminants present even more striking di- 

 stinctions : the Mastodon of Auvergne is replaced in the diluvial beds 

 by the Elephant ; and the remains of the two are never found mixed 

 together. The Rhinoceros of the Pliocene beds of Perrier is quite 

 distinct from the clumsy-proportioned R. tichorhinus of the Dilu- 

 vium, A negative character of these two deposits may be noticed : 

 the Pliocene beds do not contain the Horse or Hippopotamus ; while 

 the Diluvial beds are marked by the absence of the Tapir. 



The numerous species of Cervus of the Pliocene age have no real 

 resemblance to any existing ; while those of the later ftiuna approach 

 modern types, and one is even identical with a recent species. 



The JBoves of the Pliocene period are characterized by slender 

 forms approaching the Antilopes ; whilst, as in the case of the 

 Rhinoceros, the Diluvial species are heavy and clumsy in their pro- 

 portions. 



The Rodents cannot supply such strong proofs, owing to our igno- 

 rance of their specific forms ; at the same time the Arctomys of 

 Perrier differs from that of the Diluvium of Paris, which appears to 

 be identical with that of the synchronous beds of Auvergne. But 

 even if no appreciable difference could be detected, it is evident no 

 weight could be laid on this circumstance in considering genera so 

 prolific in species, whose very extremes are so nearly related. 



M. Pomel proceeds to show that the same character of non-iden- 

 tity of species does not obtain for the two faunas of M. Bravard, the 

 Elephantine and the Diluvian. That naturalist considers the follow- 

 ing localities as belonging to the former : — Champeix, Peyrolles, 

 Tormeil, Malbatu, Paix, La Tour de Boulade, to which M. Pomel 

 adds Anciat ; and to the latter, Neschers and Coudes. 



The Elephant is only well-known from the remains found at Mal- 

 batu, and in the alluvium extending from the foot of the Domes : 

 they present the two forms which have been named JE. primigenius 

 and E. meridionalis, which, according to M. de Blainville, are one 

 species. The Hippopotamus has only been found in the newest 

 tufaceous alluvia of Tormeil, and near Montaigu ; and all the remains 

 seem referable to the diluvial species. The Boar is also rare, and 

 the remains are found at La Toar de Boulade and Coudes ; also in a 

 cavern in the Bourbonnais, with the Reindeer, Badger, &c. ; but 

 they belong to young individuals, and cannot therefore be charac- 

 terized. The Rhinoceros is more abundant, and always with the 

 short heavy proportions of R. tichorhinus , so abundant in the Dilu- 

 vium of all Europe. 



The Horse presents here, as elsewhere, the remarkable fact of its 

 abundance in all the localities of this zoological system, under the 

 form of two species, or races ; the one tall and powerful, at Cham-
