This is apparently an easily recognizable local race rather 
intermediate between the two preceding. In size it is 
practically the same as S. n. orestes, while it differs from it 
in the absence of the light patch behind the ear and in the 
dull ochraceous of the cheeks, chin, muzzle, and sides of the 
neck, approaching very closely in these last two characters 
the typical race. 
The skull apparently differs in no way from that of 
S. n. orestes.

Note. 
Since the above paper has been in the press Mr. Miller * 
has published a list of the “* Mammals of the Natuna Islands,” 
in which he describes five new forms of this group. They 
are as follows :— | 
(1) Sccurus lutescens.—Sirhassen Island. “ Allied to the 
S. notatus from Borneo (8, vitt. dulitensis, J. L. B.), 
but considerably smaller. Colours very pale, under- 
parts buff or cream-buff.” 
(2) Scturus seraie.—Pulo Serai, S. Natunas. “ Most 
nearly allied to S. dutescens, but the upper parts 
slightly less pale and the underparts and pale side- 
stripe buff-yellow, the former without admixture of 
grey.” 
(3) Sedurus rutdliventr?s—Pulo Midei, 8. Natunas. “Size 
slightly greater than S. dutescens and S. seraie, but 
not equal to that of the Bornean or Bunguran 
representatives of S. notatus |S, vittatus, J. L. B.].
