Sus vittatus japonica, Nehring, Zool. Garten, vol. xxvi, p. 336, 1885. 



Typical locality Japan, including the Islands of Hondo, 

 Shikoku, and Kiushiu. 



Apparently allied to *S'. vittatits, but provisionally allowed 

 to rank as a separate species, as the fauna of Japan is in 

 general markedly distinct from that of Malaya. 



General colour blackish brown, with a streak from angles 

 of mouth to lower jaw and under-parts white ; ears densely 

 haired ; skull relatively wider than in S. scrofa with a higher 

 lachrymal. The white muzzle-streak is stated by Nehring 

 to occur occasionally in 8. scrofa. 



The range includes Formosa; the two races usually 

 recognised being distinguished as follows : — 



A. Size larger, ears larger S. I. leucomystax. 



B. Size smaller, ears smaller S. I. taivamis.
