8 MR. J. LEWIS BOXUOTE ON MAMMALS [Jan. 16, 



when I stated (Fasc. Malay., Zool. vol. i. p. 26) that the Malay 

 and Svimatran anhnals were indistinguishable, since they are 

 vindoubtedly distinct, the former ' being of a much yellower 

 and warmer tint. On the other hand, Messrs. Stone and Rehn 

 (Proc. Acad. Nat. Sci. Philad. 1902, p. 133) mention a Sumatran 

 specimen as approaching F. i. diversas Thos., in which the colours 

 generally are much brighter and the sides of the body nearly pure 

 chestnut. Further Sumatran material is, however, necessary 

 before this matter can be satisfactorily settled. 



The following are the races of Funambulus insignis hitherto 

 described : — 



F. insignis typicus F. Cuv. Mamm. 1821, pi. 233. Sumatra.

a-^-. 7c?,4$. Mt. Pulai S. Job ore, Nov. & Dec. 1904 and 

 Jan. 1905. 



As stated by Mr. Miller in his original description, this species 

 is similar to 2rus sahanvs Thos., but brighter and with a very 

 long tail. The extreme length of the tail is .sufficient to distinguish 

 it from all othei- members of the jerdoni group. It would appear 

 to be somewhat local, as the specimens in this collection are all 

 from Mount Pulai. The following is a short description that 

 may enable this species to be recognised : — 



Colour of uppei'and undei parts sharply divided. Above rufous 

 buft", thickly grizzled wdth black, the black being almost absent on 

 the flanks. Under pai'ts white. Feet brownish with white 

 margins. Tail bicolor and with its terminal portion white. 



Skull of typical jerdoni group, /. e, rather elongated, small for 

 size of animal, bullfe very small. 



Dimensions. Head and body 229 mm. ; tail 382 ; hind foot 

 45 ; ear 24. 



Skull — greatest length 56 mm. ; zygomatic breadth 26. 



Since the publication of my paper quoted above, Mr. Miller has 

 described several island forms of this species in Smithsonian 

 Mi.sc. Coll. vol. xlv. pp. 28 et seq. (1903).
