Notophorus, Fischer, Zool. 1819. 



These animals do not breed with the Domestic Pig, or any of the 

 genus Sus. They have not been domesticated, and very rarely 

 breed in confinement. The two species, a male {Dicotyles labia- 

 tus) and female {Notophorus torquatus), bred together in the 

 Zoological Gardens, 1864 ; they have only two teats, and have two 

 at a birth. 



Mr. E. Gerrard, in the ' Catalogue of Bones in the British Mu- 

 seum,' has pointed out that the Collared Peccary has six and the 

 "White-lipped Peccary nine caudal vertebrae (p. 289). 



M. F. Cuvier, in 'Dent. Mamm.,' observes that his description of 

 the teeth is taken from the Peccary (iV. torquatus), and the figure 

 from the Tagassu {D. labiatus) ; and he continues, "The hinder 

 molar of the lower jaw of D. labiatus is terminated by a single tu- 

 bercle as large as the others, and not by three small ones." — Dent. 

 Mamm. 211. I cannot see any difference in the form of the crown of 

 the last grinder of the two species. The teeth, like the skull, are 

 much the largest in D. labiatus.
