the female from the Gardens (1363 6). The skull has adult den- 

 tition, and it is nearly of the same size, but not so aged, as the skull 

 sent by Captain Alexander ; it differs from it in the nose being more 

 compressed and narrowed in front of the orbit. The condyles of 

 this skull are large, and separated by a broad space beneath, as in 

 all the other skulls of the genus, except that received from the 

 Zoological Society. 



A skeleton of a female, from the Camaroons, that lived in the 

 Society's Gardens (Gerrard, Cat. Bones, no. 1363 6). In the 'Ca- 

 talogue of Bones in the British Museum ' the sexes of 1363 a and b 

 are accidentally reversed. The skull had the dentition of an adult 

 animal ; the canines are very imperfectly developed, cylindrical, and 

 smooth, and the sides flattened and grooved longitudinally beneath. 

 The side of the nose of the skull is not swollen nor warty over the 

 canines, and there is only a well-marked ridge at the base of the 

 upper surface of the sheath of the upper canine. 



This skull differs from the others of the genus I have compared 

 it with in the small size of the occipital condyles, which are also 

 closer together on their under edge. The hinder nasal opening is 

 wide and rounded. 



The three skulls also differ in the form of the upper jaws in front 

 of the base of the canines. They are longer and narrower in the 

 two skulls which have been named P. larvatus (1364 a, 1364 b) than 

 they are in the skull from the Camaroons named P. penicillatus or 

 P. po7-cus (1363 a). But the two skulls with the longer intermaxil- 

 laries differ from one another, the intermaxillaries of 13646 being 

 longer and narrower than in the skull 1364 a. 



The ridges on the underside of the Ciinine of P. jieniciUatii'i 

 (1363 6) are fewer, coarser, and more irregular than they are on the 

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

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

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



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

 progeny. It will 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 Brazil ; 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 (lie 

 smaller Lepidoptera of the country, of which they collected very many 

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