Habitat. — Islands of the Rhio Archipelago (type from Batam). 



Type.— Adult female. B. M. No. 9,4,1, 511. Original number 

 927. Collected 15th July, 1908. 



Four specimens examined. 



The pigs from the islands of Batam and Bintang prove to 

 belong to a species conspicuously different in the size of their teeth 

 from 8. rJiioms, all the teeth being markedly smaller, the difference 

 being especially noticeable in the second upper incisor and the premo- 

 lars, as Avill be seen by measurements given above. With regard to 

 No. 1349, labelled as from Karimon, wlienc-e Mr. Miller records 

 Sus rhionis, we can only say that it agrees in every respect with 

 S. andersoni but whether both species realW occur on that island, or 

 the specimen has been wrongly labelled, we ai-e at present unable 

 to say. 



We have named this distinct Wild Boar in honour of Sir John 

 Anderson, g.c.m.g.. Governor of the Straits Settlements, and High 

 Commissioner for the Federated Malay States, who has actively sympa- 

 thised with the objects of the expedition. 



[We are absolutely certain that three, and three only of the 

 rhionis type of pig were collected on Batam and Bintang, and Mr. 

 Seimund is equally positive that the two pigs labelled as collected in 

 Karimon came from that island and no other. — H. C. R. and C. B. K.] 



02. TRAGULUS KANCIIIL RUBEU.S. Mill. 

 ? 730, 731, 744. Pasir Panjang, Bintang Island, Rliio Archipelago. 

 [Nowhere on the islands are mouse deer of the " kanchil " group 

 so common as the larger species or " napu," though oiu- collections from 

 the mainland are richer in the former. This group is also much less 

 liable to variation. — H. C. R. and C. B. K.] 



63. TRAGULUS KAXCHIL FULVIVENTER, Gray. 

 3 1031 ; ¥ 1121. Changi, Singapore Island. 



Com-parison with the type shows that these are undoubtedly 

 G-ray's species. Whether Miller's ravus is also identical, or whether it 

 is a northern local race, we are not at present in a position to decide. 



Topotypes of T. ravus, Miller, from Trang are now available, so that 

 this question will be shortly decided.

Though unfortunately the exact tyjie locality of T. stanleyco^vs. 

 Gray, is unknown, the present series is so closely like that species in all
