174 ^Iv. J. L. Bonhotc on the Squirrel/! 



In some specimens tlierc 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 griseicaudttf subsp. n. 

 Scinriis Preoostii, Desm., Hose, he. 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 toell 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 Sciurus Caroli. 



flab. Mount Kalulong, Baram district, alt. 2000 feet. 



Type (?, 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 Sc. 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 baiuensis, 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.
