In this animal the third molar is only just coming into place, and its very large multicuspi- 

 date posterior lobe is not so far forward relatively as in the European Wild Boar (fig. 5) 

 nor in other Indian hogs of greater age. It shows, however, very plainly the points, several, 

 if not always all of which have, by their presence in every specimen of Sus cristatus which I 

 have examined, enabled me to distinguish it from Sus scrofa, var. ferus. It has the relatively 

 short lacrymal — a tape, stretched as an arc across the long axis of the skull, from the anterior 

 inferior angle of the bone on one side to the homologous point on the other, passing over the 

 frontals, and not over any part of the nasals ; the naso-frontal suture, which lies entirely in 

 front of such an arc, is straight, and not convex backwards ; the portion of the frontal which 

 is bounded internally by the supraorbital channel, and externally by the lacrymal bone, is 

 markedly convex. The nasals are broader, as is nearly always the case, and shorter also, which 

 is not by any means always the case, relatively to the fronto-parietal region of the vertex, 

 than in Sus scrofa, var. ferus.

Fig. 7. Skull of Sus barbatus, Borneo. 1519 d, Oxford University Museum. 



This skull, like the other three skulls of the same species examined by me (of which two are 

 in the British Museum), differs from those already described in large points as well as in small 

 ones; and there can be little reason for hesitating to accept it as specifically distinct from 

 them and, indeed, from all other Suidse. 



The contour described by the middle line of its nasal and fronto-parietal regions superiorly, 

 the relations of the greatest width and greatest lengths both of the entire skull and of the nasal 

 bones, the position of the plane of its greatest interzygomatic width, not posteriorly, but in the 

 middle of the zygomatic arch, are points of large difference. The exceeding simplicity of its 

 third molars and the persistence of the mesopterygoid as a distinct bone, are points of small 

 difference, but yet of great morphological importance. In the shortness of its lacrymal bone it 

 resembles the other Suidae without facial warts. 



Its naso-frontal suture and lacrymo-frontal ridge are more like those of these pigs than those 

 of Sus scrofa.
