 As thus used, the words horse, lion, and elephant

The only region in which these three animals 

 were not found during Pleistocene times was 

 Australia, which was given over wholly to a 

 relatively insignificant and undeveloped fauna 

 of marsupials and into which it is probable 

 that man did not intrude until at a late period. 

 Everywhere else, from Patagonia to the Cape of 

 Good Hope, including regions now faunistically
