MAMMALS OK HORNKO. 29 



species is from Ttipaia ferru^s^iuca, young examples of the 

 latter can hardly be externally distinguished frcm Tnpaia 

 jmHinkd ; and one of the specimens examined and named 

 Tupauz javamca by Horsfield is clearly the young of the 

 larger species, as it is proved by its undeveloped dentation." 



I have ne\'er met with Ttipaia javauica in Bojneo. and 

 I think perhaps it is possible that specimens considered to 

 be javamca from Borneo, are merelv forms of Tiipaia minor ^ 

 which is very common in all parts of the Island. 



TUPAIA FERRUGINEA LONGIPES. 



Tnpaia ferrnginea longipcs, Thomas, Ann. and Magazine 

 of Natural History, Ser. 6, vol. xi., May 1893. 



Hind feet conspicuously longer than in the typical 

 Sumatran form. General colour less ferruginous above, but 

 more so below ; the shoulder-streak also, instead of being 

 yellowish or whitish, is rich rufous. Upper-side of tail con- 

 colorous with the back, instead of being markedly greyer. 



Skull and teeth apparently as in the typical sub-species. 



Dimensions of type (a skin) : — Head and body, J 92 

 millim. ; tail, 190 ; hind foot, 45 "5. 



This tree shtew is a long footed form of Tnpaia fcr- 

 ruginca, exapiples of which have constantly been found 

 in Borneo by Mr. Low, Mr. Everett, and myself. The 

 true Sumatran form of Tnpaia ferrnginea to the best of 

 my knowledge has not been met with in Borneo, its place 

 being taken by this longfooted sub-species. It occurs both 

 on the mountains and in the low country, ascending the 

 mountains only to the height of 2000-ft. It is rare and very 

 difficult to see in the jungle on account of its colour.

TUPAIA TANA.

p- 257 ; 



Fur moderately long and fine. It consists of two kinds 

 of hairs — long, entirely black; rather stiiT hairs, and shorter 

 hair with a sub-apical orange or dark rufous-brcwn band. 

 The former kind occurs most numerously on the interscapular 

 black band and on the hind quarters ; the orange-banded hairs 

 cover the head, where they are very short the shoulder 

 band, and a rather broad area below the interscapular
