5. Characteristic Forms of the Three Eocene Divisions. 



The few Lower-Eocene mammals which have been preserved pre- 

 sent characters of great importance. Not only are the marsupials 

 represented by .a living genus, Didelphys (Opossum), but, as Prof. 

 Gaudry has pointed out§, decided traces of a marsupial ancestry are 

 to be observed in theArctocyon and the Palmonictis — the former beiug 

 allied to the bear in its dental characters and to the Marsupials in 

 the low organization of its brain, and the latter in its teeth re- 

 sembling the Tasmanian Dasyure. They show that at this time 

 the European Carnivores were intermediate between the Marsupials 

 and the Placental mammals.
