60 THE MAMMALIA. 



had two different forms of Mastodon and the 

 Dinotherium, the principal giants among the 

 four-footed animals. Africa has only one kind of 

 giraffe. Attica possessed a giraffe surpassing all 

 the living antelopes in size, and the Helladothe- 

 riurn, an animal with short legs, it is true, but 

 larger than the giraffes in bulk. Among the living 

 Kuminants there are none that can be compared 

 with the Helladotherium ; the camel is much 

 inferior in size. Africa has but one species of 

 rhinoceros, distinguished by its rudimentary 

 incisors, whereas in Pikermi are found a rhino- 

 ceros of the African type, another of the Asiatic 

 species, and in the Acerotherium, probably also a 

 genus related to the rhinoceros. The huge thick- 

 skinned animal, the Chalicotherium, which is said 

 to have been discovered in Greece, is unequalled 

 by any in our day. The skull of the Eryman- 

 thian boar exceeds that of the wild boar by 

 one third ; and among the latter are some larger 

 than the wart-hog and the masked boar of South 

 Africa. The earth-hog (Orycteropus), the largest 

 of the Edentata in the Old World, is a miserable 

 creature compared with the Ancylotherium of 

 Attica. Lastly, the lion is surpassed by one of the 

 Carnivora of Attica, the panther by another.
