The entire dentition was in place ; the portion of the third molar which is 

 posterior to the four primary cones is very small as compared either with the rest of 

 the tooth or with its homologue in the Indian wild boar (fig. 6). It is, however, 

 considerably in front at a line drawn as a perpendicular to the plane of the cutting- 

 edges of the molars from the lachrymal canal. This skull differs markedly from the 

 skull just named in the greater length, relatively to the height, of its lachrymal bone, 

 in the greater length of its nasals relatively to the length of the fronto-parietal region, 

 in the absence of any great convexity in the part of the frontal abutting upon the 

 lachrymal, and in the convexity backwards of its fronto-nasal suture.

 No. 72. 



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

 multicuspidate 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 speci- 

 men of Sus cristatus which I have examined, enabled me to distinguish it from Sus 

 scrofa, vax. ferus. It has the relatively short lachrymal — 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,
