When Miller gave the name canescens to the Malayan 

 Greater Mouse-deer he compared it with the napu of Lingga 

 Island, later named T. pretiosus by him ' in the belief that the 

 latter represented typical T. javanicm napu. He his since 

 written " Tragulus napu. (of Sumatra) proves to be a greyish 

 animal quite distinct from T. pretiosus but somewhat closely 

 resembling T. canescens of the Malay Peninsula," 2 and again 

 later " The common peninsular Tragulus canescens differs very 

 slightly, if at all, from the Sumatran T. napu. In naming it I 

 was under the impression that the napu of Lingga Island 

 I T. pretiosus) represented the Sumatran animal. '"3 



When Wrought! >n wrote (l.c.s.) of South Tenasserim 

 animals " Geographically they should be the T. canescens of 

 Miller, but differ so markedly in several characters from his 

 description that I prefer to retain the older name," he was 

 perhaps unaware of this or that Miller's description, being 

 wrongly based, might convey a wrong impression. 



I have compared a series ranging from South Tenasserim 

 to Singapore, with specimens from Sumatra and cannot find any 

 differences: and as long as the occurrence of a distinct race in 

 the Peninsula remains unproven, as seems to be the case, 

 we have no right to use a distinct name for Malayan animals 

 which should therefore stand as T.j. napu. 



Habitat: — Sumatra and the Malay Peninsula. 



Specimens examined:- Fourteen.

"Similar to T. canescens of the adjacent mainland but 

 smaller in size and much darker in colour. Throat stripes 

 blackish brown with scarcely a trace of pale speckling. 

 Belly heavily washed with fulvous grey " {Miller). 



We have only one rather immature example from the 

 Langkawi Islands but it closely agree- with the above charac- 

 terization. It is of a richer yellow than the mainland animal 

 and more heavily clouded with blackish — the two colours 

 more finely intermixed — and the sides of neck and body and the
