524 Dr. 0. I. Forsyth Major on 



tliree quarto plates, twenty-four different types being figured *. 

 The various forms of Sus of the Indian Archipelago are com- 

 prised under the denomination of Nesosus, and the remarkable 

 fact is brought to notice that on the continent, in Cochinchina, 

 occurs an unmistakable member of the verrucosus type. 



It might be a matter of discussion whether a new generic 

 term was needed (if so, Gray's Dasychoerus would have the 

 priority) ; but at any rate its eventual utility is neutralized 

 by deliberately including in it the S. vi'ttatusf. 



Ileude apparently is acquainted with tiie Siwalik Suidse 

 only by what is reproduced of them on pi. ix. (Sus) of 

 Blainvilie's ' Osteogra|)hie' ; this might explain how lie comes 

 to state that " on sait que les origines des terrains tertiaires 

 sous-himalayens ne nous reportent pas an Xesosus^^ ^. It 

 may be seen, from what I have said above, that the contrary 

 is true. 



1. Sus verrucosus mindanensis^ subsp. n. 



Alluding to my paper in the ' Zool. Anzeiger ' §, Nehring || 

 declares that lie cannot completely approve of the somewhat 

 radical manner of my reducing all the living species of Sus 

 to tiiree or four, viz. S. barbatus, S. verrucosus, S. vittatus, 

 S. scrofa. 



My proceeding might perhajo more apj)ropriately be termed 

 conservative, wiiilst 1 woukl call radical the introducing of 

 about 35 new species of Sus by Pere Ileude. xVpart from 

 this, from what Nehring lornierly stated on the same sub-

 Art und Weise, in welcher i^t>r,si/M Major in .seiner . . . .Abhandlung, die 

 sammtlioben lebenden .S'M«-Art<'n auf 3 resp. 4 reducirt, niimliclj auf 

 iS'. barbatus, S. verrucosus), S. vittatus, luid eventuell .S'. scrofa, kann ich 

 nicht ganz billigeu. Einerseits ist S. celebensig nacb nieiner A:isicht 

 eine '^nite Art,' andererseits linden sich unter den von Forsytb Major zu 

 S. vittatus gerecbncten Formen mebrere, welche von einander sicher 

 unterschitdtu werden kiinuen '' [here reference is made to two of the 

 author's papers, ' Zuol. Anz.' 1885, p. 352, and ' Zool. Garten,' 1885, p. .'534, in 

 which similar opinions were expressed] ; " uberhaupt ist die Auscinander- 

 lialtung der einzelneii Looal-Kjissen resp. .Subspecies bei den Wild- 

 schweinen von unzweifelhafter Bedeutung fiir ein tieferes Eindringen in 

 den Process der Artbildung uach Kuum und Zeit. was auch Forsyth 

 Major anerkeniit."
