XXXVIII. — On some new Mammalia from the East-Indiati 

 Archipelago. ]>y Oldfield Thomas. 



The Britisli Museum owes to Messrs. Charles Hose and 

 Alfred Everett a coUeetiou of Mammals from North Borneo, 

 and in working them out the following new species prove to 

 need description. The Mount Dulit species will be more 

 fully described in a general account now in preparation of 

 the Mammals obtained by Mr. Hose in that most interesting 

 locality. 



Hemi(jale Hosei^ sp. n. 



Size and proportions of //. Ilardwickei. General colour 

 above from nose to tail uniform dark smoky brown, without 

 dorsal or nuchal markings, A spot on each side of the 

 muzzle, another over each eye, ears, and chin, white. Teeth 

 markedly smaller than in II. Ilardwickei. 



Dimensions : — 



(c?) Head and body 540 millim. ; tail 320; hind foot 78 ; 

 basal length of skull 89. 



Hab. Mount Dulit, N. Borneo, 4000 feet (C. Hose). 



Tiipaia Everetti^ sp. n. 



Size large ; as large as T. tana. Fur short, close, and 

 rather harsh. Tail-hairs scarcely or not longer than those of 

 the body. General colour unitbrm dull rufous-brown ; the 

 head rather more olive-brown; an indistinct ferruginous stripe 

 over each shoulder. Underside similar to upper, but rather 

 j)aler; throat more rufous. Tail cylindrical, not bushy; its 

 hairs, except at the tip, rarely exceeding 10 millim. in length, 

 its colour quite like that of the back. 



Skull with the elongate tapering form of that of T. tana, 

 though the muzzle is slightly shorter. Zygomatic vacuities 

 very small, only about 1*5 x TO millim. 



Teeth, except ,"3, very large and stout, markedly heavier 

 than those of T. Uma. -L^ nearly twice the height and more 

 than twice the antero-posterior diameter of that of T. tana ; 

 internal lobes of 1^ and ^li very well developed. First and 

 second lower incisors as usual, but the third one minute and 

 ncarl}' vertical, markedly contrasting with the ri of T. tana, 

 ^vhieh is well tleveloped and nearly horizontal, like ~i Ji'id ~j- 

 On the other hand, the lower canine, to match ihe heavy L-r,
