This was first pointed out by Nathusius * with reo^ard to 

 S. verrucosus proper, from Java. He stated that in Sas the 

 transverse section of tlie lower canine forms a triangle ; but 

 whilst in Sus scrofa the posterior side is, next to the anterior 

 one, the broadest, and the outer side only half as broad as the 

 first named, in Sus verrucosus the outer side has almost 

 double the breadth of the posterior one. A similar state- 

 ment was made by Riitimeyer f, who, in his last paper on 

 the subject t, figures transverse sections of the lower canines 

 of Sus verrucosus, vittatus, and scrofa. 



The character alluded to, as well as the other distinctive 

 characters of S. verrucosus, escaped the notice of J. E. Gray, 

 when, in 1873 §, he figured and described three skulls belong- 

 ing to the verrucosus-type, classing them into three distinct 

 genera : the Sus verrucosus of Java, and " S. celebensis, 

 Mull. & Schleg.," of Celebes, are called Dasychoerus; a variety 

 of the same from Amboina (Moluccas) is mistaken for 

 a S. vittatus, and figured and described as the type of 

 "Aulacochoerus vittatus " ; whilst an immature skull of the Sus 

 verrucosus from Java is introduced as a new species of Sus, 

 S. mystaceus \\ ; and an immature skull of the Celebes 

 variety of S. verrucosus^ from Macassar, is called Sus 

 timorensis. 



The Wild Hog from Ceram was rightly considered by 

 Gray, in 1868^, to be a variety of S. verrucosus; in the 

 Hand-list (1873) the " var. ceramicus " is cancelled again, 

 the Ceram Wild Hog figuring simply as Sus verrucosus.
