Sciurus iiotatus nnd allied Species. 451 



the race should not be given a separate name, but noted 

 under the iianio of the species from whicli they arc as yet 

 but im|)crfL'ctly (lefined. 



Mr. Miller took this view with regard to a specimen from 

 Pulo Kiabu when dealing with S. anainbensis, and, as far as 

 I am able to judge without seeing the actual specimens, it 

 seems a pity that he did not act likewise with regard to 

 S. Abhotti. 



Sciurus villains dulilensis, subsj). n. 

 Sciurus notutus, Bodd., Iloso, Mamni. Borneo, p. 4(5 (1893). 



General colour throughout as in iSciurus i-lflalus ti/picus^ 

 with the following exceptions: — Tiie tail is always anniihited 

 right to the end and has no red pencil, though in some cases 

 it has a slight tinge of rufous near the tip, but the annulations 

 are always visible. The lateral light strij)e is duller and less 

 buflfy in tint, being cream-buff*, as compared with buff* in 

 the typical iorm. The colour of the underparts is [)ale orange 

 (orange-bufl*). 



The skull shows hardly any difference except in being 

 slightly narrower. 



Dimensions (from skin): — Head and body 213 millim. ; 

 tail 200 ; hind foot 44. 



Skull (anotiier specimen): greatest length 51 millim.; 

 length of palate from heriselion 21; zygomatic breadth 30; 

 interorbital breadth 17; leiigth of nasals 14; breadtii of 

 nasals, ant. 7, post. 4.

The colour of the under|)arts of this form ai)pears to vary 

 between the same limits as in the typical race, but whereas in 

 Sumatra and the Malay Peninsula the dark form seems to 

 predominate, in l^orneo the converse is the case. The absence 

 of the bright red j)encil to the tail forms the best-marked 

 character by which this species may be distinguished. 



AVhen the underjjarts of this sj)ecies arc deep chestnut it 

 somewhat resembles S. baluensis, which I describe 1 in a 

 recent ])aper, when dealing with the various forms of 

 S. Prevostii. S. baluensis is easily recognizable by its 

 much larger size and darker colour of the upper parts.
