i\.-c. 2 in., 3 f. Kuala Teku, Tahan River, Pahang. 500 ft. July and 

 August, 1905. 



A very typical series. 



[Common in submontane tracts and deep jungle throughout the 

 southern part of the Peninsula. — H. C. R.] 



U. SCIURUS HIPPURUS, Geoffr. 



Sciurus hippurus, Is. Geoffr. Etudes Zool,, No. 6, pi. 6 (1832)

b. m. Kuala Teku, Tahan River. 500 ft. 31st July, 1905. 



Evidently a somewhat scarce species in the Peninsula. 



15. SCIURUS CONCOLOR, Blyth. 



Sciurus concolor, Blyth, J.A.8.B., xxiv., p. 374 (1855) ; Bonh., op. 

 cit., p. 20. 



Sciurus caniceps, Gray, Blauf. Mamm., p. 380 ; Flower, op. cit.,

a., b. /. Kuala Tembeling, Pahang River. 200 ft. August, 1905. 



[Though very common in Selangor and Pahang, this squirrel seems 

 to reach its southern limit in the territory of Malacca. It is not re- 

 corded from Johore. — H. C. R.] 



16. SCIURUS TENUIS, HofcSJ?. 



Sciurus tenuis, Horsf., Zoo!, lies. (1824) ; Flower, op. cit., p. 357 ; 

 Bonh., P.Z.S., 1906 (1), p. 5. 



a.-f. -1 m., 2 f. Gunoug Tahan, Pahang. 3,300 ft. June, 1906. 



These belong to the dark-coloured form of this squirrel and re- 

 present, therefore; the true Sc. tenuis. 



On Gunong Tahan three specimens of a squirrel, nearly allied to 

 Sc. tenuis, were procured, which I propose to call. 



17. SCIURUS TAHAN, sp. mv. 



Very similar in general appearance to Sc. tenuis, from which it 

 differs in being larger and darker. The general colour of the back is 

 very dark with numerous yellow annulations to each hair. The general 

 greyish appearance of the true Sc. tenuis is quite absent. The 

 yellowish-patch on the outside of the thighs, a noticeable feature in 

 the true Sc. tenuis, is hardly to be made out. Tips of the hairs of the 

 tail are yellow not white, and the tail shows distinct black and yellow 

 annulations, a good distinctive character.
