H. Syriacus, they are exclusively confined to Africa. They 

 are all gregarious little animals, living in holes of the rocks, 

 and capable of domestication. Some forms (Dendrohyrax) 

 are arboreal in their habits. The "coney" of Scripture is

believed to be the Hyrax Syriacus, which occurs in the rocky 

 parts of Syria and Palestine. Another species the Hyrax 

 Capensis, or "Klipdas" ("badger of the cliffs ") occurs com- 

 monly in South Africa, and is known by the colonists as the 

 " badger." 



No fossil remains have as yet been discovered which can 

 with certainty be referred to this order. 



ORDER XI. PROBOSCIDEA. The eleventh order of Mammals 

 is that of the Proboscidea, comprising no other living animals 

 except the Elephants, but including also the extinct Mastodon 

 and Deinotherium. 



The order is characterised by the total absence of canine teeth; 

 the molar teeth are few in number, large, and transversely ridged 

 or tuberculate; incisors are always present, and grow from per- 

 sistent pulps, constituting long tusks (fig. 417). In living Ele- 

 phants there are two of these tusk-like incisors in the upper jaw, 

 and the lower jaw is without incisor teeth. In the Deinotherium 

 this is reversed, there being two tusk-like lower incisors and 

 no upper incisors. In the Mastodons, the incisors are usually 

 developed in the upper jaw, and form tusks, as in the Ele- 

 phants, but sometimes there are both upper and lower in-
