352 AN ELEMENTARY TEXT-BOOK OF BIOLOGY. 



ing only Tarsius spectrum, found in Sumatra, Banca, and Borneo; 

 also outside the Oriental region in Celebes). 



Peculiar Genera (besides those in the above families). Tragulus 

 (chevrotain) ; Cervulus (a deer) ; Bibos (wild cattle) ; three p.g. 

 of antelopes. Platanista (a dolphin found in Ganges and Indus). 

 Three p.g. of Muridce; Pteromys (a flying squirrel) ; Acanthion 

 (a porcupine) ; Gymnura (a hedgehog). Eleven p.g. of bats. 

 Twelve p.g. of V'werridw ; Cuon (a dog); five p.g. of Mustelidce; 

 two p.g. of bears. Loris and Nycticebus (lemurs). Four p.g. of 

 apes, including Simla (orang-utan), and Hylobates (gibbon). 



Peculiar Species. Among these are the Indian tapir, several 

 species of rhinoceros, and the Indian elephant. 



IV. Australian Region. Twenty-eight families represented, of 

 which eight are peculiar i.e., seven out of the eight families o! 

 Marsupials, and the two families of Monotremes. All of these, 

 however, are absent from Polynesia and New Zealand. 



Peculiar Genera (besides those in the above families). Babimsa 

 (a hog), and Anoa (a small kind of cow) in Celebes. Five p.g. of 

 Muridce in Australia, and one of these in Tasmania also. Three 

 p.g. of bats. 



Absent Forms. Australia and New Guinea possess no non- 

 aquatic Mammals higher than Marsupials, except some bats, mice, 

 and rats. This points to extremely long-continued isolation, 

 which has afforded time for the Marsupials to become modified 

 in the most diverse directions, thus enabling them to fill places 

 elsewhere occupied by other orders. New Zealand is remarkable 

 for the absence of all indigenous Mammals, so far as certainly 

 known, with the exception of two bats. 



V. Neotropical Eegion. Thirty-seven families represented, of 

 which seven are peculiar i.e., Bradypodidce (sloths), Dasypodidce 

 (armadilloes), and Myrmecophagidce (true ant-eaters). Chinchillidw 

 (chinchillas) and Camidce (cavies) among Kodents. Cebidce (New 

 World monkeys) ; Hapalidce (marmozets). The Phyllostomidce 

 (leaf-nosed bats) are peculiar, with the exception of a Californiari 

 species. 



Peculiar Genera (besides those in the above families). Chiro- 

 nectes and Hyracodon (opossums). Dicoctyles (peccary, also in 

 Texas) ; Auchenia (llama) ; Elasmognathus (a tapir). Inia (a 

 dolphin, upper part of Amazon basin). Six p.g. of Muridce; six 

 p.g. of Oclodontidce (rat-like forms), two of them peculiar to W.
