Teeth : combined breadth of upper incisors 11*2 ; antero-posterior length of p^ 4-6, pjj 4-9, P_3 5 7 , t 6*1, ^ 4*8, ™? 4-3; greatest transverse diameter of p^ 6'6, of ml 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 //. hardwickei is proved by the white patches on the muzzle, the white ears, whitish underside, 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. W e may therefore expect that other specimens of it will turn up as the mountain-systems of N. Borneo are more thoroughly explored. 2. HERPESTES SEMITORQUATUS, 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, Temin. 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 higher mountains of the Oriental region. 4 . TUPAIA TANA, Raff. a. 4000 feet. 10/91. 5. TUPAIA MONTANA, Thos.1 a. 3. 5000 feet. 14/10/91. Type. b. 2 • 3000 feet. 25/9/91. c. Immature 3 • 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, hut 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 1 L. c. p. 252. 16* |
