32 GUIDE TO THE AUSTRALIAN MUSEUM. 



implies that the animals composing it have an odd number of 

 toes, one or three, on each hind foot. The existing genera are 

 Avidely separated in other respects, but fossil forms complete 

 the series and justify their being grouped together. 



The Rhinoceroses (Hhinoceros sondaicus and Ceratorhinus 

 unmalniisisj^ ou the lloor of the Central Hall, are natives of 

 .Java and Sumatra, wlicre they live in the marshes and swamps. 

 They have three toes on each foot ; species of the former genus 

 have one horn, the latter two, placed on the snout. There 

 are mounted specimens on the floor of the Central Hall, and 

 also a skeleton in the Osteological Hall. 



The Tapir (Tajm-us sumatranus) is in a case; and {T. leucogenys), 

 is on tloor of Central Hall. These are usually nocturnal in 

 their habits and are found in the swamps and rivers of South- 

 eastern Asia, and of South America. Their snout is prolonged 

 till it may be called a short trunk. 



The Horse. The genus Equus includes wild and domesticated 

 horses of all kinds, asses, and zebras. These have one toe only 

 in use on each foot, corresponding to our middle finger, and they 

 walk on the point of it. A skeleton of a horse is exhibited ou 

 the first landing of the staircase. 



The Zebra {Equus hurcheWA to be seen on the floor of the Central 

 Hall, is a native of South Africa. Two mounted specimens are 

 exhibited, and a skeleton is in the end case of the Osteological 

 Hall. 



Sub- Order IV.— Artiodactyla (derived from Gr. artios, 

 even ; daktylos, a finger), implies that the number of toes on 

 each foot is even — two or four. This sub-order is aofain divided 

 into non-ruminant and ruminant animals. In the former the 

 teeth have tuberculated crowns ; in the latter they are crescent 

 shaped. 



THE NON-KUMINANTS are the Pigs or Boars and the 

 Hippopotamus. 



Section I., Suina. The Pigs have four toes visible, two of 

 whicli are covered by hoofs, but the other two are not fully 

 developed; they have a long snout capable of considerable 

 motion, and very small eyes. In some of the Wild Pigs the 

 canine teeth grow into large curved tusks. In America the Pigs 

 are represented Ijy the Peccaries, which differ in a few respects
