of the tail are elongated and elegantly curved towards 

 and over tiie tip of the tail, so that the total impression 

 is that of a lyre; in an older specimen (from Goram), measuring 

 88 cm., these hairs are still more elongated, but the flat 

 tail ends in the same lyre-shaped figure; in a still older speci- 

 men (from Tidore), measuring 106 cm., the elongated hairs 

 have been weared off so that the tail ends in a flattened strong 

 brush, along the sides the hairs are diminishing in length. 



A few words concerning the ear of niger compared with 

 a papuen sis- ear : as far as can been studied from dried 

 skins it makes the impression as if the ear of papxiensis 

 has in all ages a more or less oval shape, meanwhile in 

 niger the lower half of the outer margin of the ear des- 

 cribes a broad circular line; moreover the ear of niger is 

 larger than in papuensis. 



In our collection are skins from Tidore, Ternate, Goram, 

 and Waaigeou. 



Conclusion. 



The different islands of the East Indian Archipelago are 

 inhabited by the following species: 



Sumatra — Sus vittatus and oi. 



Borneo — Sus barhatus. 



Java — Sus verrucosus and Milleri. 



Celebes (North) — Sus celebensis. 



Celebes (South) — Sus Nehringii. 



Saleyer — perhaps a distinct species, «S. Weheri. 



Timor — S. timoriensis. 



Flores — -S. fioresianus. 



New Guinea with adjacent islands — S. papuensis and S. niger. 

 Pulo Laut, North Natuna islands — *S. natunensis., described 

 in 1901 by Mr. G. Miller Jr. I never saw a specimen of 

 these islands however. 



Amboina — S. amhoinensis Major; Ceram — aS. ceramicus 

 Gray; and Borneo — S. horneensis Major are absolutely 

 unknown animals to me, so that I have no opinion at all 

 as to their specific value.
