Sciurus notatus and allied Species. 451 
the race should not be given a separate name, but noted 
under the name of the species from which they are as yet 
but imperfectly defined. 
Mr. Miller took this view with regard to a specimen from 
Pulo Riabu when dealing with S. anambensis, 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. Abbotte. 
Scturus vittatus dulitensts, subsp. n. 
Sciurus notatus, Bodd., Hose, Mamm. Borneo, p. 46 (1893). 
General colour throughout as in Sciurus vittatus typicus, 
with the following exceptions :—The tail is always annulated 
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 stripe is duller and less 
buffy in tint, being cream-buff *, as compared with buff * in 
the typical form. The colour of the underparts is pale orange 
(orange-buff *). 
The skull shows hardly any difference except in being 
- slightly narrower. 
Dimensions (from skin) :—ILead and body 213 millim. ; 
tail 200; hind foot 44. 
Skull (another specimen): greatest length 51 millim.; 
length of palate from henselion 21; zygomatic breadth 30; 
interorbital breadth 17; length of nasals 14; breadth of 
nasals, ant. 7, post. 4. 
Hab. Borneo. 
Type B.M. 94. 6. 2.21, g ad. Mount Dulit, 1000 feet. 
Collected and presented by Messrs. Charles and Ernest Hose. 
The colour of the underparts of this form appears 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 Borneo the converse is the case. The absence 
of the bright red pencil to the tail forms the best-marked 
character by which this species may be distinguished. 
When the underparts of this species are deep chestnut it 
somewhat resembles S$. baluensis, which I described in a 
recent paper, when dealing with the various forms of 
S. Prevostii, SS. baluensis is easily recognizabie by its 
much larger size and darker colour of the upper parts.
