MAMMALS OF BORNEO. 47 



Measurements of the type (an adult skin) : — 

 Head and body 175 millim. ; tail, without hairs 109, with 

 hairs 144 ; hind foot, without claws, 40 ; Skull, tip of nasals to 

 bregma (centre of fronto-parietal suture), 36 ; zygomatic 

 breadth, 24*5 ; mterorbital breadth, 14 ; length of nasals, 157 ; 

 breadth of nasals anteriorly, 5" 2, posteriorly, 4 ; palate length, 

 24"2 ; diastema, 12 ; length ot tooth series, 87. 



A second specimen in the British Museum is rather larger, 

 measuring : — Head and body, 180 millim. ; tail, without hairs, 

 118 ; hind foot, 4o"5. This species is superficially by no means 

 unlike S. chincusis, Gr., or S. lokruili, Hodgs., agreeing with 

 both in its general size, and its uniforiu dull grizzled olive 

 colour ; but it may be readily distinguished trom either by its 

 elongated muzzle, which allies it rather to the four follows 

 ing species. Of these, 8. laticmidatus is separated by its larger 

 size, shorter hair, browner colour, nearly white belly, and still 

 longer muzzle ; S. rufigcnis by the brilliant rufous of its cheeks 

 and the underside of its tail ; S.pcnivi hy its similarly rulous 

 tail ; and S. bcrdjnorci by the black and white longitudinal 

 stripes with which its body is ornamented. No other species 

 that I can find has any close relationship to this form, which 

 was discovered by Mr. Everett.

I have met with only two specimens of this squirrel on the 

 mountains of the Baram district, and those only on Mount 

 Dulit at 400c feet. 



Size about equal to that of S. tenuis, Horsf. General 

 colour of upper surface yellowish grey, strongly suffused with 

 orange on the head and along the centre of the back. Hairs 

 dark slaty grey for four-fifths of their length, their tips yellow 

 or orange. Face grey, but with white rim round each eye. 

 Flars extremely short, rounded, their edges white or pale 

 yellow, and standing out in a marked contrast against a patch 

 of woolly black hairs situated just behind them on the sides of 

 the neck. Hairs of chin, chest and belly slaty grey basally, 

 dull yellowish white distally ; line of demarcation on sides 

 quite gradual. Limbs coloured as in S. tcnm's ; hind soles 

 hairy for their proximal 8 millimetres. Tail slender, the hairs 

 being comparativ^ely short, only about 10 or 12 millim in 

 length ; these hairs are broadly ringed with orange basally, 

 and have a black subterminal and a white terminal band.
