1889.] MAMMALS OF KINA BALU. 235 



11 to the centimetre ; short-haired, sharply bicolor from base to tip, 

 brown above, yellowish white below. 



Dimensions, 2 : — Head and body (probably stretched), 177 m ilir. 

 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 lij ; interorbital breadth 7*4 ; palate, 

 length 1 9 ; 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 alticola is confined to the 

 higher parts of Mount Kina Balu. 



18. Mus MUSSCHENBROECKI, Jcnt. 



a, b. 1000 feet. 3/87. 



c,d.S 2- 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 EPHippiuM, Jent. 



a, 6. ad. andjiiv. 1000 feet. 3/87. 



It appears rather doubtful whether this species is really distinct 

 from Mus concolor, Ely., 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 with them. 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. S. 1876, p. 739. 

 a. juv. 3000 feet. 3/4/88. 



This specimen is the fourth example of the interesting genus 



> Ann. Mus. Geuov. (2) v. 1889.
