auiraal lias recently been published by Dr. Murie, in 

 the Geological Magazine. We justly regard the 

 Mammalian fauna of modern India as one of the 

 noblest in the world ; but it is paltry in comparison 

 with that of the much more limited Miocene India; 

 even if we suppose, contrary to all probability, that 

 we know most of the animals of the latter. But if 

 we "consider the likelihood that we do not yet know a 

 tenth of the Miocene animals, the contrast becomes 

 vastly greater. 



Miocene America is scarcely behind the Old World 

 in the development of its land animals. From one 

 locality in Nebraska, Leidy described in 1852 fifteen 

 species of large quadrupeds ; and the number has 

 since been considerably increased. Among these are 

 species of Ehinoceros, Palaeotherium, and Machairo- 

 dus ; and one animal, the Titanotherium, allied to the 

 European Anoplothere, is said to have attained a 

 length of eighteen feet and a height of nine, its 

 jaws alone being five feet long. 



In the illustration, I have grouped some of the 

 characteristic Mammalian forms of the Miocene, as 

 we can restore them from their scattered bones, 

 more or less conjecturally ; but could we have seen 

 them march before us in all their majesty, like the 

 Edenic animals before Adam, I feel persuaded that 

 our impressions of this wonderful age would have 

 tar exceeded anything that we can derive either 

 from words or illustrations. I insist on this the 

 more that the Miocene happens t< be very slenderly
