Specimens Examined. — Twenty-four from East and one from 

 West Perlientiau Island. 



Remarks. — The black colour on the rump |H)S8ess»Ki by the i\]ni \» 

 frequently absent, the under- parts vary from buffy-wliite t«» lemnn 

 yellow, and the short hair, clothing the lower side of the tail, from 

 buffy-white to pale ocliraceous. 



The long tail, wliich generally exceeds the l.-iigth of head uiid 

 body, renders the species conspicuous. It needs no comparisou with 

 T. lacernata, which is a small member of the same suft-group. nor with 

 the yery different T. helatigeri and T. (ihscnm \ with exception of the 

 tail it is in all dimensions, botli body and cranial, a trifle smaller than 

 the typical form inhabiting Singapore.* 



I have not been able to compare T. Joiuilrtnnii with s)HH-ini(>uii of 

 T. pulonis, Miller, from Aor Island, foun(h'd on two examples only. 

 The latter race is said to l)e {larger than T. ferrii>jiii»'(t. but the cruniiil 

 measurements of the type are consideral)Iy less than thos«« of nuuiy 

 Singapore animals, though the collector's external mejuJun-mentH 

 are, as Miller states, considerably larger. As the tail xn sliorter tluin 

 the length of head and lioily. the colour of the fmck that of T. Jr-rnhjinf^t. 

 and the rostrum relatively l>roader and more robust than th.- latt^-r. 

 the Perlientian Island aniinal does not aj.pear to n.i-d elos4« com|Niriiiuu 

 with it. 



Of the numerous; species of T///'<»/<' whi.-h I havi« colhvtiMi 

 personallv, T. longimiKJa with T. nirohnrini. /♦•lelmr. and itii »ul>- 

 species T. (N.) snrda, Miller, f alone are truly arl)on'al in habit. An a

 where thev live and feed. or. at most. «'limb o.-ca.Hionally into low 

 bushes: in them the tail is shorter than th.' h.-ad and \»hU Imirlh. 

 The above-named animals, which an' m«'t with i; 

 have the habits of squirrels, all posse.ss ;t ».iil fl> 'f i- •
