ORDER PACHYDERM ATA. 40? 



Guineensis of Brisson and Klein, and the Sus Porcus of 

 Linnaeus. It is known only by the account and figure given 

 by Marcgrave. Its size is small, like the Siamese, but it 

 is particularly distinguished from all other races by its 

 elongated and pointed ears, and its tail descending almost 

 to the ground. Its coat is frizzled, but soft in comparison 

 with other pigs. It is of a reddish colour. The head seems 

 rather slender. It is said to be frequently exported from 

 Guinea to America. 



The Masked Boar, (Sus Larvatus.) This species is dis- 

 tinguished by a fleshy prominence on the fore part of the 

 head, entirely enveloping the upper half like a mask. It 

 is a native of the Cape, nearly the size of the European 

 Boar, and has all its proportions. The only distinction is in 

 the fleshy protuberances. From the head to the eyes it is 

 of the usual figure, but from under the eyes commences 

 this protuberance, which gradually diminishes towards the 

 snout. Thus there appear to be two heads, the half of the 

 one being as it were enclosed in the other. This Boar 

 also appears, according to the figure of Daniel, to have on 

 each side of the face, under the eyes, two other very large 

 excrescences, the surface of which is very irregular and 

 wrinkled. The peculiar characters of the skull correspond 

 with this facial mask. They principally consist in the 

 great developement of the external edge of the alveolus of 

 the upper canine. This edge, in the Common Boar, does 

 not exceed an inch in elevation ; whereas in the species of 

 which we are treating, it is developed into a long apo- 

 physis, and terminates in a broad tuberculated swelling, 

 corresponding to the similar tubercles of the middle part 

 of the bones of the nose. 



The head of this species is, moreover, distinguished by a 

 large arch formed by the cheek-bones, and by the long 

 surface to which the muscles of the trunk are attached. 



The habits of this animal are little known, but it ap- 

 pears to be very wild, dangerous, and intractable.
