TAHAN EXPEDITION. 



23. MI'S CILIATUS, BONHOTE, 



Mus ciliatus, Bonh., P.Z.S., 1900, p. 879. 



a.m. Gunong Tahan. 3,300 ft. 24 th June, 1905. 



This individual agrees very closely with the type specimens in all 

 particulars. As there was some slight confusion over the exact mea- 

 surements in the former specimens, I append the measurements of the 

 present example taken in the flesh : 



Head and body, 245 mm. ; tail, 333 mm. ; hind-foot, 47 mm. ; ear, 

 '27 mm. 



[Though nowhere common, this magnificent Eat seems widely 

 spread over the mountains of the Peninsula. The types are from 

 Grunong Inas in the north of Perak, while the Selangor Museum 

 possesses a fine specimen trapped on Bukit Kutu, Ulu Selangor, at 

 a height of about 3,000 ft. — H. C. E ] 



2A. MUS CREMORIVEXTER, Mill. 



Mus cremoriventer, Miller, Proc. Biol. Soc. Wash., xiii., p. 144 

 (1900) ; Bonh., op. cit., p. 36. 



a. /. Gunong Tahan. 4,700 ft. 4th July, 1905. 



This specimen appears to be rather larger than the typical series 

 from which this species was described and from the specimens in the 

 British Museum, but it agrees in all its other characters with the 

 description, so that I have no hesitation in referring it to M. cremori- 

 venter, and more especially so as the hind-foot measurements agree. 

 The dimensions of this specimen are : 



Head and body, 134 mm. ; tail, 185 mm. ; hind-foot, 28 mm. ; ear, 

 18 mm. 



to. Mi s IX as, Bonh. 

 Mus inas, Bonh., P.Z.S., 1906 (1), p. 9, pi. 1. 

 a. /. Gunong Tahan, Pahang. 3,303 ft. 1st June, 1905. 

 Agrees very well with the type, but is slightly paler. 



2C>. MUS COXCOLOR, Blyth. 



Mus concolor, Blyth, J.A.S.B., xxviii., p. 295 (1859) ; Blauf. Mamm., 

 p. 408 : Flower, op. cit., p. 361 ; Bonh., op. ext., p. 38 ; id., P.Z.S., 1906 

 (L),p. 11.

 Hystrix grotei (Gray) ; Bonh., op. cit.. p. 39. 

 a. Kuala Tenibuling, Pahang River. 2l>0 h. August, 1905. 

 An immature specimen, closely resembling the type.
