3. POTAMOCHCERUS . 



Sancjlier de Madagascar, Daubenton ; Buffoii, H. N. xiv. 39G ; 

 Flacourt's Hist. Madagasc. 151. 



Hab. Madagascar. 



Mr. Sclater informs me that a species of this genus from Mada- 

 gascar is living in the Jardiu des Plantes at Paris. 1 am not aware 

 that any specimens from that country have reached England. 



b. Domestic Swine. Face short. The ear more or less de- 

 pendent, often very large. Animal black, white, or mottled. 

 Young like parent {not yellow-streaked). Skull short ; facial 

 line sunken; forehead and upper surface of the nose flattened, 

 more or less distinct, margined on the sides. 



I do not believe that the Domestic Pig is derived from the Wild 

 Boar of Europe, any more than the Domestic Cat is derived from the 

 Wild Cat of Scotland, or the Dog from the Wolf of Europe ; nor do 

 I know of any exotic species of Pig from which it is likely to have 

 been derived. 



There is no doubt that the Domestic Pig will breed with the Wild 

 Boar, and that there are hybrid breeds which are more like the Wild 

 Boar than the normal domestic animal. On the other hand, (he 

 wild species are often more or less domesticated in the countries they 

 naturally inhabit ; but these animals differ little from the wild pro- 

 genitors, and are very different from the true domestic animals. 



4. SCROFA. 



Face conical, smooth, or nearly so. Skull — sheath of the canine 

 with a more or less distinct longitudinal crest across the base. 



ScROFA DOMESTICA.

 Skull rather short ; crown rather convex {Buffon^. 



Hab. Siam. I have not seen the variety. 



Daubenton describes the skeleton (v. p. 181). This has most unac- 

 countably been confused with the Chinese Pig by Desmarest, Fischer,
