laries differ from one another, the intermaxillaries of 1364 b being 

 longer and narrower than in the skuU 1864 a. 



The ridges on the underside of the canine of P. penicillatus 

 (1363 h) are fewer, coarser, and more irregular than they are on the 

 canines of the two other skulls (1364 a and h). The back and front 

 sides of the canines are rounded in 1363 a, while they are flat in 

 1364 a and h ; but the two latter differ considerably, in flatness. 



This species has bred in the Society's Gardens, and reared the 

 progeny. It wiU not breed with the Domestic Pig, or at least has 

 not done so. 



Marcgrave describes it as having a cyst on the navel, and says 

 that it had been introduced by the negroes, and naturalized in 

 Brazil. 



I suppose that the Pig has not been found profitable, or was not 

 fitted for the American climate, as the breeding of it has been dis- 

 continued. I have inquired of persons who have lived in different 

 parts of BrazU; they all state that they have never seen or heard 

 of the Painted Pig in that country ; nor do I find any account of it 

 in the modern works on the natural history of the country. Mr. J. 

 Miers, F.R.S., has observed that Marcgrave only knew of the north- 

 ern provinces of Brazil, then in possession of the Dutch, and that 

 perhaps it still breeds there. My son and daughter, who travelled 

 in those districts, and first made entomologists acquainted with the 

 smaller Lepidoptera of the country, of which they collected very 

 many new species, state that they never saw any Eed Pig there.

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

 gascar is living in the Jardin des Plantes at Paris. I am not aware 

 that any specimens from that country have reached England. 



b. Domesticated Swine. Face short. The ears more or less dependent, often 

 very large. Animal black, white, or mottled. Young like parents (not 

 yellow-streaked). Skull short ; facial line sunken ; forehead and upper 

 sii/iface of the nose flattened, more or less distinct ; nose margined on the 

 sides. — Gray, I. o, p. 38. 



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, the
