The U. S. National Mu.seuni oontains Oi^ Malayan pig.s (51 skins and 

 ()2 skulls) presented by Dr. W. L. Abbott. This collection, especially 

 rich in local species of the Sus rittiffus group, was made in the region 

 extending from the Natuna Islands on the east to the Nicobar and 

 Andaman Islands on the west, and from Tenasserim and the Mergui 

 Archipelago on the north to Engano on the south. Four particularly 

 interesting specimens from Johore have also been contributed by Mr. 

 C. B. Kloss. Although this material has been gradually accumulating 

 for nearly ten years, I have been able to publish very little concern- 

 ing it, owing to lack of information with regard to the exact status of 

 some of the earlier-described Malayan species. During a recent visit 

 to Europe I was enabled, through the courtesy of the directors of the 

 various institutions, to examine the collections of pigs in the Natural 

 History Museum in Berne, the Natural History Museum and Agricul- 

 tural High School in Berlin, the Natural History Museum in Leyden, 

 and the British ^Museum in London. Observations on all of this 

 material form the subject of these notes. 



I.— THE SUS BARBATUS GROUP. 



^Nluch confusion ha^ existed with regard to the members of the Sus 

 harhafii.^ group occurring in Borneo and Sumatra, some authors sup- 

 posing that there are three species, others that there is only one. 

 This is the result not so much of the lack of specimens as of the 

 circumstance that each writer has worked separatelv and without con- 

 sulting the material studied b}' others. The series that I have exam- 

 ined show that the two islands arc inhabited b}^ at least three species, 

 but that the status of these forms has hitherto been very imperfectly 

 understood. 



The first member of the group to be made known, the Bornean Sirs 

 harhatus^ was briefly described in 1839" by Midler, who subsequently''
