174 Mr. J. L. Bonhote on the Squirrels 
In some specimens there is a tendency for the shoulders to 
become tinged with rufous. I have examined specimens of 
this squirrel from the Miri River and from the lower slopes of 
Mount Dulit. 
Sciurus Caroli grisetcauda, subsp. n. 
Seiurus Prevostii, Desm., Hose, loc. cit. p. 45 (partim). 
The whole of the upper parts, including the feet, crown of 
head, sides of face and neck, and tail, of a uniform grizzled 
greyish, darker on the fore limbs and slightly lighter on the 
sides of the neck and thighs, occasionally white on the latter, 
the sides of the face more or less suffused with rufous. ‘The 
lateral white line narrow and starting well behind the 
shoulder, but widening out slightly on reaching the thighs. 
The sublateral black stripe always broad and well marked. 
Underparts, inner sides of limbs, and a ring round the eye 
chestnut, as in the preceding form; the insides of the ears 
are also slightly suffused with the same colour. 
Dimensions as in Scturus Carolt. 
Hab. Mount Kalulong, Baram district, alt. 2000 feet. 
Type 3, B.M. 93. 6. 1. 5. February. Presented by 
Mr. Charles Hose. 
This squirrel, which shows a wide limit of variation, with 
a great tendency towards the preceding form, may never- 
theless always be readily distinguished by the very broad and 
well-marked black sublateral stripe, which in Se. Caroli 
typicus is generally absent, but if present is very faintly deve- 
loped. It appears widely distributed in the Baram district, 
specimens having been received from most of the mountains, 
including Mount Dulit, Batu Song, Niah, Bakong. 
Sciurus baluensis, sp. n. 
Whole of the upper parts, including the sides, neck and 
face, and outer sides of the limbs and feet, uniform grizzled 
brownish olive, slightly darker along the median line, the 
top of the nose, feet, and sides of the face being more or less 
suffused with chestnut, each hair being dark brown with one 
or two fulvous annulations. The lateral light stripe is short, 
narrow, and light yellow in colour, and loses itself before 
reaching the thighs. The sublateral black stripe is broad and 
well marked and of equal length with the lighter stripe. The 
remainder of the underparts, muzzle, and a ring round the 
eye chestnut. Tail deep black, with no sign of annulations.
