them black and white mixed. In about half the series the hairs of the 
distal half of the tail are black tipped. 
S. jinlaysont jfinlaysoni has been recorded by Anderson from the 
mainland, by Flower from the Banpakong River, by Bonhote from the 
Menam at an altitude of 75 metres, by Wroughton from the Menam 
and Cambodia, and by Gyldenstope from the Korat Plateau. 
Sciurus finlaysoni folletti. 
Type. Adult female (skin and skull) No. 1991/CBK. Collected 
on Koh Phai, Inner Gulf of Siam, 2nd February, 1915. 
Characters. Pelage generally greyish yellow ; size small. 
Colour. Hairs of pelage above deep neutral grey at base, at tips 
ivory yellow, top of head slightly deeper yellow ; the sides of head, fore 
and hind limbs greyer owing to decrease in the yellow element, pro- 
bably due to wear. Below, the base of the fur is light grey and the 
yellow tips are less distinct. Axillae and groin slightly washed with 
tawny. ‘Toes of fore and hind feet blackish, the hairs only slightly 
tipped with yellow. Tail above rather paler than back, below slightly 
yellower, the distal half obscurely banded grey and ivory yellow: the 
tip blackish. Vibrissae black. 
Skull and Teeth. Do not differ the from the Koh Si Chang race of 
S. finlaysont either in size or characters. 
Measurements. Har 21, Skull: basilar length 36.6, braincase 
breadth 22, proximal breadth of nasals 3.4, distal breadth of nasals 6. 
For other measurements see table p. 162. lars of the series * 19— 
23 mm. 
Specimens examined. Thirty-eight ; seventeen males and twenty- 
one females, all from the type locality. 
Remarks. This squirrel is subject to a certain amount of varia- 
tion. When the pelage is abraded, as is frequently the case, the dorsal 
region is considerably darker and greyer than as given above. Insome 
animals there is no tawny wash on axillae and groin, in others these 
areas are pale chesnut and the lower abdomen is also suffused with this 
colour. 
One example has the tail ivory white throughout as in S. jinlaysoni 
portus from the neighbouring island, two or three have the tip only 
darkened, while in a number of the specimens the tail is throughout 
* Measured by native collector.
