UNGULATA. 



This well-known species is very nearly allied to the living 

 H. amphihius of Africa, and it at one time extended its range 

 over the whole of the south of Europe, and abounded in 

 Britain. 



By some paleeontologists the genus Meryco2wtamus, of the 

 Upper Miocene of the Siwalik Hills, is referred to the Hii)- 

 2)02)otamida', and it certainly has strong affinities with this 

 family. On the other hand, its molars exhibit selenodont 

 characters, which would ally it with the Euminants, while 

 it has other characters which bring it very close to Antlira- 

 cothermm among the Suida. 



Fam. 2. Suida. — The group of the Suida, comprising the 

 Pigs, Hogs, and Peccaries, is very closely allied to the pre- 

 ceding ; but the feet (fig. 624) have only two functional 

 toes, the other two toes being much shorter, and hardly touch- 

 ing the ground. All the three kinds of teeth are present, 

 but they vary a good deal. The canines (fig. 641) typically

formidable tusks projecting from the sides of the mouth. 



The incisors are variable, but the loM^er ones are always
