3381. The skull of a Collared Peccary (Dicotyles torquatus). 



The teeth have been removed from the right side of the upper and left side of the under 

 jaw. The skull is remarkable for the strong ridge which extends from the lower border of 

 the malar bone and the malar process of the maxillary. The pterygoids have not the fossae 

 which were noticed in the Babyroussa and Wart Hogs. 



Hunterian. 



3382. The premolars and molars of the right side of the upper jaw of the same 

 Peccary (Dicotyles torquatus). Hunterian. 



3383. The second premolar, p 2, the last true molar, m 1, with portions of the 

 intervening teeth, p 3, p 4, m 1 and m 2, of the left side of the lower jaw of 

 the same Peccari (Dicotyles torquatus). Hunterian. 



The following, to No. 3401 inclusive, are parts of the same skeleton of the Collared Peccari 

 (Dicotyles torquatus). 



Hunterian. 



3384. The skull. 



The right lower canine has been shed and its socket obliterated. 



3385. The atlas. 3386. The axis. 



3387. The sixth cervical vertebra. 



It is remarkable for the size of the pleurapophysial part of the transverse process, which is 

 coextensive with the centrum at its base, and spreads out both forwards and backwards, as 

 it extends downwards and outwards. 



3388. The six hinder dorsal vertebrae. 



They show the backward inclination of the three anterior and the forward inclination of 

 the three posterior neural spines. 



3389. A dorsal or thoracic rib. 



3390. The sacrum. 



The first neural spine is free, and separated from the second by an oval hole ; the neural 

 spines of the second, third and fourth sacral vertebrae, although their limits are definable, 

 coalesce. The lower end of the fourth spine becomes confluent with the succeeding spine, 

 and this with the spines of the anterior caudal vertebrae, forming a rough and broad ridge.
