NO. 1976. TREESHREWS: FAMILY TUPAIIDJ3—LY0N. 85 



Its chief distinguishing feature is the lack of annul ations on the hairs 

 of the tail, generally dark color, and the small size of skuU. On 

 Sumatra, Singkep, and the Anamba Illands are Tupaias which, 

 wliile evidently belonging to this splendidula group, are much closer 

 to T. glis ferruginea than is T. splendidula itself. I have not seen 

 Kolilbrugge's Tupaia millleri, but the description would indicate it 

 to be an example of T. splendidula. Neither have I seen Glipora 

 rufescens "b" and "c" of Jentink's Catalogue,^ judging by the 

 name they may be examples of this species, Mivart's Tupaia rufi- 

 caudata was an accidental publication of Gray's manuscript name. 

 Gray had evidently intended to call the species ruficaudata, but really 

 published the name as splendidula, forgetting to change ruficaudata 

 on the label of the specimen. As Kolilbrugge points out, attention 

 to this species was first called by Miiller and Sclilegel' who con- 

 sidered it a hybrid between "Hyl. tana and ferruginea." Not un- 

 likely it is specimen "(Z" under Tupaia ferruginea fromBanjermassin 

 in Jentink's catalogue of mammals in the Leyden Museum.^ In the 

 Berlin Museum is a skull witliout skin from Kutei, a district on the 

 east coast of Borneo somewhat north of Klumpang Bay, where 

 Doctor Abbott collected two examples. I have identified it as 

 Tupaia splendidula, but not without some reservation, as I was un- 

 able to make a direct comparison with known splendidula skulls. 



Specimens examined. — Five, four from southern Borneo, and one, 

 the type, probably from Borneo. See table, page 87.
