horned species, the best known is the Indian Rhinoceros (^. 

 Indicus QKunicornis} which was probably the ' Unicorn " of the 

 ancients. Another species with one horn (R Sondaicus} 

 inhabits Java, Sumatra, and Borneo. Of the two-horned 

 species, one (R. Sumatrensis) is found in Sumatra and the 

 Malay Peninsula, and is remarkable for the comparative 

 absence of cutaneous folds. The best known, however, is the 

 African Rhinoceros (R. bicornis) which occurs abundantly 

 in Cape Colony and in the southern parts of the African 

 continent (fig. 250). Another African species is the White 

 Rhinoceros (R. simus), distinguished from the preceding by its 

 colour, the shortness of its upper lip, and the great length 

 of the anterior horn.

Fam. 2. Tapiridtz. The Tapirs are characterised by the 

 possession of a short movable proboscis or trunk. The skull

 these are unsymmetrical (the little toe being smaller than the 

 rest and not touching the ground), and the hind-feet have only 

 three toes, all encased in hoofs. The jaws are furnished with

Several species of Tapir are known, of which the most fami- 

 liar is the American Tapir (T. Americanus), which inhabits the 

 vast forests of South America. It is a large animal, some- 

 thing like a pig in shape, but brownish black in colour, and 

 having a mane. It is nocturnal in its habits, and is strictly 

 phytophagous. The proboscis is employed in conveying the
