NO. 21 FIFTY-ONE NEW MALAYAN MAMMALS — MILLER _'■ | 



Sumatran forms of the group, while it exactly applies to the one oc- 

 curring on Singapore Island, where Raffles obtained much of his 

 material, I have no hesitation in regarding Singapore as the true 

 type-locality. The neglectus of Schlegel thus'becomes an exact syno- 

 nym of femoralis Martin.
