68 SOME VISITS TO BATAM ISLAND. 



think it will be the P. cana, Miller, of Pulo Kuhdur 

 and E. Sumatra rather than P. rhionis, Miller, of 

 Bintang Island. These are local forms of P. femoraUs 

 which, though found in the Peninsula and Sumatra, 

 does not occur on the islands of the Rio-Lingga Archi- 

 pelago. 



3. Macaca nemestrina, Linn. The. " beroh " was said to 



occur but has not yet been taken in the Archipelago. 



4. M. fascicularis, (Raffles). The " krah " is common 



everywhere. 



5. Cynopterus montanoi, Robin. Bats, apparently of this 



species, were fairly common and were the only kind I 

 obtained. Malay nama " klawar." 



6. Galeopithecus volans, Linn. The " kubong " was said to 



occur. 



7. Tupaia ferruginea batdmana, Lyon. This new sub- 



species of the " tupai tanah " was exceedingly common. 

 Externally it only differs from T. ferruginea, Raffles, 

 in its slightly greyer tail. It is easily separated how- 

 ever by its longer and wider skull. 



8. Arctogalidia simplex, Miller. This is the Archipelago 



form. A specimen, the third known, was shot early 

 one morning while it was running along the branch of 

 a high tree. As the people called it a "musang" 

 which they said was common I presume that 



9. Paradoxurus hermaphroditus, Pallus, or an allied form 



occurs. 



10. Mus concolor, Blyth was taken in the Kampongs where 



it was not uncommon. 



11. Mus fir mus, Miller, is the Sumatran form of the Penin- 



sula M. validus, Miller. I have never taken these 

 except on the banks of fresh water streams. 



12. Mus lingensis, Miller. The Sumatran form of Mus 



surifer, Miller. A dry jungle rat and exceedingly 

 common. It seems to begin feeding at early twilight 



Jour. Straits Branch.
