IV. MAMMALIA. 27 



The Eared Seals --{Otarmlre) have small external ears, and a 

 beautiful soft under-fur. They are better able to get about on 

 land than the Phocidce. The Seals found on the coast of N.S. W. 

 are { Arctocephahis cinereus, and {Stenorhynchus leptonyx) the 

 former i& a Fur or Eared 8eal ; the latter commonly called the 

 Sea Leopard, is one of the Phocidce. Specimens are shown in 

 the Upper Floor, (_ entral Hall. 



The Walrus — [Trichechidce) of which there are two species, are 

 distinguished by their immense canine teeth, which project 

 downwards like tusks to a length of twenty inches or more. 

 Skulls of both species are exhibited in the Osteological collection. 



Order IV— INSEOTIVORA.— This order comprises a 

 number of small animals, such as Moles, Shrews, and Hedo-ehoo-s 

 which feed on insects and worms. They are found in all parts 

 of the world, except Australia and South America. The molars 

 of animals of this order are sharp serrated teeth, but the teeth 

 vary considerably in the different genera. They are nearly all 

 nocturnal animals, that is they come out by night to search for 

 food and sleep by day ; and some of them hybernate, or remain 

 dormant during the winter months. 



The MOLES {Taljndce) are formed for burrowing in the earth. 

 They have short powerful claws, very small eyes, and beautifully 

 soft fur, which will lie either way, and offers no impediment to 

 the animal's progress through its tunnels. But one group of 

 Moles [Myogale) has its feet and tail modified so as to fit it for an 

 aquatic life. They are represented by : — 



The Coninion 'NLo\e—[Talpa europcea) of Europe. 



The Water Mole — [Myogale pyrenaka) from the Pyrenees. 



The Golden Mole — (Ghnjsochloris capensls and 0. villosa) from 

 the Cape of Good Hope. 



THE SHREWS (Soricidce) are little animals very like 

 mice in outward appearance. 



THE K^DGEKOGrS—iFrinaceidce) are well known by 

 their spines, and their habit of rolling themselves into a 

 ball for defence purposes when frightened. 



The Common Hed^elaO^—iErinaceus europceus) is a native of 

 Great Britain and other parts of Europe.
