1889. | MAMMALS OF KINA BALU. 235 
11 to the centimetre ; short-haired, sharply bicolor from base to tip, 
brown above, yellowish white below. 
Dimensions, ? :—Headand body (probably stretched), 177 m ilm. 
tail 162; hind foot 32; heel to front of last foot-pad 16. 
Skull: tip of nasals to lambda (junction of sagittal and lambdoid 
sutures) 34; nasals, length 15; interorbital breadth 7:4 ; palate, 
length 19; length of anterior palatine foramina 6; upper molar 
series 5'8. 
This species is most nearly allied to the Nepalese M. niveiventer, 
Hodgs., but may be distinguished by its unspeckled back, by the 
more gradual passage of the upper into the lower colour, and by its 
larger size. 
So far as its collector has observed, Mus ulticola is confined to the 
higher parts of Mount Kina Balu. 
18. Mus wuUSSCHENBROECKI, Jent. 
a, 6. 1000 feet. 3/87. 
e,d.3 9. 3000 feet. 18 and 20/3/88. 
It is of considerable interest to find this species, previously only 
known from Celebes, in Borneo, on a different side of the line 
separating the Oriental from the Australian regions. Its occurrence 
here suggests that other members of the Oriental element in the 
peculiar Celebean fauna may also prove to have survived on the tops 
of the Bornean mountains. 
19. Mus eEpurprium, Jent. 
a, b. ad. and juv. 1000 feet. 3/87. 
It appears rather doubtful whether this species is really distinct 
from Mus concolor, Bly., found in Burma and the Malay Peninsula; 
but for the present I do not feel justified in definitely uniting the 
two forms, and the Kina Balu individual clearly belongs rather to 
the Sumatran ‘ ephippium’ than to its northern ally. 
20. CHIROPODOMYS GLIROIDES, Bly. 
a. 1000 feet. 1/88. 
This specimen is immature, but would not apparently have ever 
reached the dimensions of the two individuals obtained by Mr. 
Wallace at Sadong, and now in the British Museum. However, it 
exactly matches some of those collected by Signor L. Fea in Burma 
and Tenasserim, and is evidently specifically identical withthem. In 
the general account now in course of publication of the collection 
made by that gentleman’ some further details as to the character 
and synonymy of this beautiful little species will be found. 
21. TRICHYS GUENTHERI, nom. nov. 
Trichys lipura, Giinth. P. Z. 8S. 1876, p. 739. 
a. juv. 3000 feet. 3/4/88. 
This specimen is the fourth example of the interesting genus 
' Ann. Mus, Genoy. (2) v. 1889.
