ROOM III. FOSSIL MAMMALIA OP AUVERGXE. 357 



by Mr. Waterhouse, from the eocene marls and limestones, near 

 Clermont ; fresh-water shells are associated with the bones, and 

 no traces of marine remains of any kind have been discovered. 



The bones and teeth, though friable, are in a beautiful 

 state of preservation ; and Mr. Waterhouse has most success- 

 fully developed some exquisite crania and jaws of an extra- 

 ordinary little extinct Pachyderm (not larger than a rabbit) 

 which inhabited ancient Auvergne. 



There are bones and teeth of many genera of Anoplothe- 

 ridse. 



Anthracotherium, several species. 



Cainotherium : a sub-family of Anoplotheridse. 



A small and very peculiar Ruminant. 



An animal approaching the Musk-deer (Amphitragalus of 

 M. Pomel). 



Hysenodon (found, also, at Hordwell, in Hants). 1 



Many small Rodents of species and genera discovered by 

 Searles Wood, Esq., in the eocene deposits, at Hordwell, in 

 Hants. 2 



Small carnivora, allied to the Weasels. (Mustelidce.) 



Jaws of small marsupials. (Didelphidce.) 



Fresh- water Turtles. (Emydians.) 



Crocodilian and batrachian reptiles. 



Small lacertian reptiles. 



Birds : several species and genera. 



Eggs of birds, and probably, also of reptiles. 



For the above list of this highly interesting series of mam- 

 malian remains from the tertiary lacustrine deposits of the 

 volcanic regions of France, I am indebted to the kindness of 

 Mr. Waterhouse ; when this collection is thoroughly arranged, 

 and the characters of the species and genera are determined, it 

 is to be hoped this accomplished naturalist will lay before the 

 public a full account of these palseontological treasures. 



TROGONTHERIUM CUVIEKI. Wall-case G. The rivers of 

 England and of the Continent were inhabited by Beavers at 

 no very remote period, and in more ancient times extinct 

 species or sub-genera of this family, of a large size, were de- 

 nizens of modem Europe. In the lowermost compartment of
