Type locality. — Indragiri River, eastern Sumatra. 



(Teographlc (lUfrihatlon. — Eastern Sumatra; Rhio Archipelago 

 (Pulo Kundur"); Banka. 



Characters. — Upper length of skull of adult male 460-505 mm. ; gen- 

 eral form of skull as in Sn.'< harhatus; last molar both above and below 

 smaller than in the Bornean animal, the upper tooth retaining all its 

 elements, but with its posterior portion much narrowed, the lower 

 tooth (Plate XLIX, tig. 3) lacking the terminal heel, but with the third 

 transverse ridge reduced to a terete heel-like remnant (see also the 

 figure published by Volz). ^ 



Measurements. — For measurements, see table, pages 755 and 756. 



SpeGinneiis examined. — Nine, from the following localities: Indra- 

 giri River, Sumatra, 1; Falembang, Sumatra, 2 (Berne); Banka Island, 

 4; Pulo Kundur, Rhio Archipelago, 2. 



Remarks. —This species is distinguisha))le from Sus harbatus chiefly 

 by the reduced size and complexity of the posterior lower molar, a 

 character shown by the type and by one of Doctor Yolz's Palembaug 

 specimens, the only adults yet known with this tooth in good condi- 

 tion. No tendenc}' toward a similar reduction could be detected in 

 any of the twenty-seven adults of Sus harhatus that I have examined. 

 It is very probable that, as Doctor Jentink states, the skull is more 

 elongated than in the Bornean animal. Though the material thus far 



"Though Pulo Kundur is the only island of the Rhio Archipelago from which 

 specimens have been examined, the animal probably occurs throughout the group 

 wherever sufficiently extensive forests remain. In a letter dated April 21, 1904, 

 Doctor Abbott writes: "Sus oi is found on the other islands of the Rhio Archipelago. 

 A watchmaker named Maw here in iSingapore, who i^ a great shikari, told me that 

 they got four — one big boar, a sow, and two smaller pigs — a few Sundays ago over on 

 Pulo Batam, opposite Singapore, behind the little island Nongsa. He had never 

 seen them before and did not know what they were. They put the four carcasses 

 into a sampan and started to tow them to Singapore by their lannel. But the sam- 

 pan capsized and all were lost." In a more recent letter (May 14, 1904) he adds 

 that seven of these i>igs instead of four were killed on Pulo Batam, and that Maw has 

 never seen tlu' animal in the neighborhood of Singapore, although he has been 

 shooting there for many years.
