both double-rooted. Lower teeth as in T. minor except that c is 

 smaller and P and p larger in proportion, so that the tooth-row 

 appears as a whole to be more uniform.

Head and body 12.5 millim. ; tail 136 ; hind foot 29*7. 



Skull : basal length 30 ; greatest length 36, greatest breadth 17-7 ; 

 nasal length 13 ; interorbital breadth 10 ; intertemporal breadth 14 ;

This beautiful little species is the most interesting of the Tupaite 

 obtained, as it forms a connecting-link with the two species belonging 

 to the genus Dendrogale. That genus was founded by Dr. Gray and 

 recognized by Dr. Anderson in his recent review of the Tupaiidce 

 mainly on account of its cylindrical tail, black-and-white banded 

 cheeks, and the absence of the usual shoulder-stripe. Now T. mela- 

 nura on the one hand has a tail even slenderer and more cylin- 

 drical than D. murinu and B. frenata, and has no shoulder-stripe, 

 while on the other its face-markings are quite as in Tupaia. One 

 character, however, distinguishes Dendrogale, or at least D. frenata, 

 from all the Tupaia;, namely the extremely small size of the claws, 

 both fore and hind; and so far as this character is coucerned 

 T. melanura is a true Tupaia, as it has claws quite as large in 

 proportion as the other species. For the present therefore I consider 

 it to be a Tupaia, and leave the validity of " Dendrogale " as an open 

 question to be settled when further, and especially spirit-, specimens 

 are obtained. 



8. SciTJRUs BicoLOR EPHippiuM, Tcmm. 

 a. $. 4000 feet. 10/91. 



9. SciURUS PREVosTii, Dcsm. 



a,h. cJ ?. 5000 feet. 10/91. 



Both these specimens are of the grey-backed form of this species, 

 like specimens a-c of the Kina Balu collection. 



10. SciuRus NOTATUS, Bodd. 

 a. <S- 3500 feet. 20/9/91. 



This specimen, like the Kina Balu examples of the species, is of 

 the blue-bellied type, and Mr. Hose remarks that he obtained 13 

 skins, all like this one, during the same month. 



11. SCIURUS BROOKEI, ThoS.' 



a. <S. 3800 feet. 25/9/91. 



b. 2. 5000 feet, 10/91. Type. 



About the size of Sciurus lokriah, Hodgs., or rather smaller ; 

 decidedly larger than S. tenuis, Horsf. General colour above plain 

 olive-grey, grizzled with yellow, but not so finely as in -S*. tenuis.
