8 MR. J. LEWIS BOXHOTE OX MAMMALS [Jan. ] 6, 



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

 and Sumatran animals were indistinguishable, since they are 

 undoubtedly distinct, the former being of a much yellower 

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

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

 specimen as approaching F. i. diver sus 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 satisfactoi-ily settled. 



The following are the races of Funmnbulus insignis hitherto 

 described : —

a-k.7S,4:2- Mt. Pulai S. Johore, Nov. & Dec. 1904 and 

 Jan. 1905. 



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

 is similar to Mios sahanv.s Thos., but brighter and with a very 

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

 it from all other members of the jerdoni grouj). It would ajopear 

 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 upper and under parts sharply divided. Above rufous 

 buff, thickly grizzled with black, the black being almost absent on 

 the flanks. Under parts white. Feet brownish with white 

 margins. Tail bicolor and with its terminal portion Avhite. 



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

 size of animal, bullte very small. 



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

 45 ; ear 24. 



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



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

 described several island forms of this specie.s in Smithsonian 

 Misc. Coll. vol. xlv. pp. 28 et seq. (1903).
