and lips as being dirty flesh colored, eye-lids and hoofs black. 



Although the skull may be said to merit to be placed 

 between barbatus and verrucosus with regard to its slender- 

 ness it in reality is of a much more compact shape and 

 higher in proportion to its length ; this highness results 

 from the very high lower jaw, meanwhile its shortness 

 is caused by the shorter jaws, the anterior upper premolar 

 being placed near to the canine and the distance between 

 first and second lower premolar being a very short one, 

 and the like the distance between canine and hindest lower 

 incisor being a good deal shorter than in barbatus and 

 verrucosus] like in barbatus the premaxilla surpasses the 

 anterior border of the upper-incisors; the upper molar 

 series is like in verrucosus pushed backwards, but the bony 

 palate does not extend so far backwards as in that species; 

 the hind-most molars though nearly as broad are much 

 shorter than in verrucosus. 



The profile-line is convexe, in very adult skulls straight 

 or very feebly impressed on the posterior parts of the 

 nasalia; the eye-hole is larger than in verrucosus, the malar 

 deeply excavated ; in vittatus as in verrucosus the parietals 

 never seem to meet so closely behind as to form a crista 

 like in very adult barbatus, and that notwithstanding I 

 have before me skulls of the two species with very used 

 molars and where the sutures between parietals and frontals 

 entirely have vanished. 



Sus vittatus for the rest seems to be a very strong 

 animal, armed with enormously developed canines; indeed 

 Dr. Hagen relates specimens of its boldness (cf. Tijdschrift 

 van het Kon. Nederl. Aardrijksk. Genootschap, 1890). 



Sus vittatus is living in Sumatra. 



5. Sus Milleri, n. sp. 



Very young specimens are broadly banded like in vit- 

 tatus; a nearer inspection shows that the anterior part of 

 the yellowish red bands ends in a large spot, an other
