128 THE WANDERINGS OF ANIMALS [OH. 



Hyaenas, since Miocene in England and Asia, now 

 in the whole of continental Africa and the south- 

 west quarter of Asia. Both the striped and the 

 spotted kind, the latter now only in South Africa, 

 lived in interglacial England. 



The dog- tribe date from late Eocene in North 

 America and Europe, now cosmopolitan even in the 

 Falkland Islands, but absent from Antilles, Madagascar 

 and to East of Wallace's line. Australia is overrun 

 by the Dingo, a dog of unknown origin. 



The genus Canis was not ready until the Pliocene. 

 Weasels and otters have the same wide range. 



Bears appear as various genera in Eurasian 

 Miocene. The genus Ursus appeared with the Plio- 

 cene, and with the Pleistocene entered North America, 

 ranging into Mexico and reappearing on the Andes. 

 Although inhabiting all Asia and until recent days 

 all Europe, bears never seem to have found their way 

 into Africa proper, excepting the Atlas range. 



Elephants. 



The earliest archaic elephantine beasts have been 

 discovered in Egyptian Upper Eocene : Moeritherium 

 and Palaeomastodon, the latter with a pair of upper 

 tusks pointing downwards, and a pair of lower, spoon-
