Dimensions (from skin) :—Head and body 275 millim., 
tail 280, hind foot 55. 
Hab, Mount Kina Balu, Borneo, alt. 1000 feet. 
Type &, B.M. 95.10. 4.11. Collected March 1887 by 
Mr. J. Whitehead. Presented by Mr. Oldfield Thomas. 
‘There are also specimens from Mount Dulit up to 5000 feet 
in no way differing from the above. 
I am somewhat doubtful as to the specific distinctness of 
this form from Se. erythromelas of Schlegel from Celebes ; 
but in view of the distinctness of the Bornean fauna from that 
of Celebes, it seemed best to consider it specifically distinct 
until an opportunity occurs of comparing it with Celebean 
specimens. 
Scturus baluensis suffusus, subsp. n. 
Considerably smaller than the previous form. The whole 
of the upper parts as in Se. balwensis, but the colour absolutely 
uniform throughout and without any rufous on the feet or top 
of the nose. ‘Ihe sides of the face and a ring round the eye 
are pure chestnut, but the muzzle is paler. The tail is similar 
incolour to the back, The presence of the light lateral stripe 
is only faintly indicated by a lighter tinge about the centre 
of each side, and the sublateral black stripe, although 
distinct, is very short.
