MAMMALS COLLECTED IN SIAM. 369 
Crawford writes of the Si Chang Islands, “The only quadrupeds 
which we observed on these islands, were a large species of rat, and 
a small squirrel about a foot long. This last was numerous in the 
forest, and we obtained several specimens. It was of a milk-white 
colour, the paws excepted, which were black. “(2nd Ed. Vol. I, pp. 
296, 7 (1830 ), and in a footnote states, “ This appears to be a new 
species, and Dr Horsfield has appropriately named it after the late 
Mr. Finlayson.”

underparts without any distinct rufous areas. 
Upper parts:—hairs at base neutral grey on the back, paler 
on the head and side; the distal halves dirty yellowish white (pale 
olive buff) the extreme tips black. The middle back is generally 
blacker owing to local reduction of the pale annulations, but this 
dark area is very variable in extent and in two or three animals is 
practically absent. The limbs and sides of the head and neck are 
grey slightly tinged with brown and finely and faintly grizzled with 
whitish ; hands and feet blackish slightly grizzled ; ears like the head, 
their backs grey bordered with whitish. 
Below a variable sullied grey largely grizzled, but axillary _ 
and inguinal regions and the undersides of the thighs whitish. The 
median line is slightly darkened and the underparts are faintly 
margined from the sides. 
Tail cream-colour generally grizzled with black at the base, 
the central hairs of the pencil black. Some of the hairs between base 
and tip have faintly blackened ends and the median line of the 
underside is nearly always somewhat blackened — in many specimens 
markedly so. 
In a few animals there are indications that rufous areas may 
occur down the median line of the chest and abdomen and at the
