of the Sciurus Prevostii Group. 173 
The next species with which we have to deal is 
Scvurus atricapillus, Schlegel. 
Sciurus atricapillus, Schlegel, op. cit. p. 27, pl. ii. fig. 1. 
Sceiurus redimitus, Boon Mesch, Temm. Esq. Zool. Guin. p, 245 (partim) 
(1853). 
In this species, according to the describer, the underparts 
and inner sides of limbs alone are chestnut. The tail is black, 
shading to rufous-brown. The white lateral stripe is 
narrower and the sublateral black stripe much broader than 
in Se, Prevostit typicus. The top of the muzzle and feet are 
black, the remainder, including all the upper parts, is covered 
with black hairs annulated with fulvous, which is rather 
paler on the thighs, cheeks, and sides of the neck. 
Hab. Kapouas River, east of Pontianak, Borneo. 
The next is a species in which we get a highland and a 
lowland form, the limit being roughly at 1000 feet, and 
neither of these appears to have been hitherto described. They 
come from the Baram district of Sarawak, and the large 
series in the Museum has been almost entirely collected by 
Mr. Charles Hose. For the lowland form I propose the 
name 
Sciurus Caroli, sp. n. 
Sciurus Prevostii, Desm., Hose, Mamm. Borneo, 1893, p. 45 (partim). 
Top of the head, neck, and shoulders dirty fulvous white, 
each hair being dark at its base, with a broad fulvous tip, 
Remainder of back narrowing down towards the root of the 
tail dingy black, each hair being black, with two narrow 
fulvous annulations. Lateral stripe from behind the shoulders 
and the whole of the outer side of the thighs and hind limbs 
white. Underparts, feet, sides of neck, cheeks, face, and rim 
round eye pure chestnut, also the ears, although these latter 
show a tendency to become grizzled. ‘Tail broadly annn- 
lated with black and pale fulvous. Sublateral black stripe 
very faint or absent. ; 
Dimensions (from skin) :—Head and body 275 millim., 
tail 250, hind foot 55. 
Hab. Marudi River, Baram district. 
Type 9, B.M. 99. 12. 9. 59. 26th May, 1898. Col-
