H92.] MAMMALS FROM NORTH BORNKO. 223 



breadth 18"S ; tip to tip of postorbital processes 22'5 ; inter- 

 temporal breadth 14'3 ; palate, length 54, breadth at posterior 

 corner of p^ 25 ; length of palatine foramina 5*2 ; greatest diameter 

 of infraorbital foramina 59. 



Teeth : combined breadth of upper incisors 1 1*2 ; antero-posterior 

 length of pi 4-6, F] 4-9, p! 57, P_' S'l, ^^ 4-8, ^ 4-3; greatest 

 transverse diameter of p^ 6'(i, of i^^ 5"5. 



This striking species is certainly the chief prize of the collection, 

 as new Carnivores are very rare, and so distinct a new species has 

 not been described for many years. 



That H. hosei is not simply a melanism of H. hardwickei is proved 

 by the white patches on the muzzle, the white ears, whitish under- 

 side, and also by the differences in the size of the teeth. 



Some animal similar to this, and possibly of the same species, was 

 seen by Mr. Whitehead on Mount Kina Balu, and it is certainly 

 very unlikely that an animal of this sort should be confined to one 

 mountain. We may therefore expect that other specimens of it will 

 turn up as the mountain-systems of N. Borneo are more thoroughly 

 explored. 



2. IIerpestes SEMiTORauATUS, Gray. 



a. 2000 feet. 23/9/91. 



The Museum possesses a specimen of this rare Mungoose from 

 Baram, besides the type, of which the exact locality in Borneo was 

 not recorded. 



3. Rhinolophus luctus, Temm. 



a. 2- 4000 feet. 29/9/91. 



As remarked by Dr. Dobson, this Bat is a regular highland species, 

 and seems to occur on all the hiirlier mountains of the Oriental 



4 . TUPAIA TANA, Rilff. 



a. 4000 feet. 10/91. 



5. TUPAIA MONTANA, ThoS.' 



a. d. 5000 feet. 14/10/91. Type. 



b. $ . 3000 feet. 25/9/91. 



c. Immature 6- 4000 feet. 10/91. 



Size much as in Malaccan specimens of T. ferruyinea (Bornean 

 ones are rather larger), but the tail shorter in proportion. General 

 colour above dusky olive, with a strong rufous suffusion ; head clearer 

 olive. Back, in fully adult specimens, with a deep black median 

 line running from the withers to the rump, but broadening out and 

 becoming less sharply defined in its posterior half. Under surface 

 greyish orange, the hairs grey at their bases, broadly washed 

 terminally with rich olive-yellow. Tail concolorous with the body, 

 not greyer, as it is so markedly in T. ferruginea ; grizzled black and 

 shining ferrugineous above ; below the central short-haired part is
