GREAT GAME ANIMALS. 



present exhibited. This animal is allied to the Wart-Hog, but 

 has the skull less specialised. 



The Wart Hogs -^ r * cau Wart- Hogs (Phacochoerus) take 



their name from the large wart-like lobes* 

 GenilS PhacOCllcerilS. pro j ect i ng f rom the sides of the face, but are 

 [Case 65.] m0 re particularly distinguished by the character of the dentition. 



In young animals there is a total of thirty-four teeth, of which 

 one pair (canines) forms huge tusks, while there is one pair of 

 upper, and three of lower incisors. Of cheek-teeth there are six 

 upper, and five lower pairs; the first three upper and the first two 

 lower being premolars, and the remaining three in both jaws 

 molars. In very old animals only the tusks and last molars 

 may remain. The tusks are large in both sexes ; and the 

 last molar is a long and complex tooth, formed of a number 

 of closely-packed vertical columns. Unlike those of ordinary 

 Wild Pigs, the young are uniformly coloured. There are two 

 closely allied species or varieties of the genus ; namely, the 

 Northern P. cdiani (1352), represented by a skeleton, and the 

 Southern P. cethiopicus (1353), of which a male and female, 

 presented by Mr. F. C. Selous, are shown. In habits they 

 resemble the majority of the Pig-family, although they frequently 

 take up their abode in the deserted burrows of the Aard-Vark. 

 When driven out from such strongholds, they rush with great 

 ferocity upon the dogs and hunters. They usually associate in 

 pairs or small family-parties. 



The Babirusa. The Wild Boar ' or Babirusa ("Pig-Deer"), of 



Celebes, Babirusa alfurus ( 1 354 1, alone represents 

 GenilS Babirusa. a g enus distinguished by the extraordinary de- 

 [Case 65.] velopment of the tusks of the male. These teeth grow continuously, 

 and are long, slender, curved, and devoid of enamel.; those of the 

 upper jaw curving upwards, and piercing the skin without entering 

 the mouth. The number of teeth is thirty-four; there being only 

 two pairs of upper incisors, and two of premolars in each jaw. 

 The skin is very rough and almost entirely devoid of hair. A 

 mounted specimen and several skulls are exhibited.
