SCIURUS EXILIS. 



Schirns cx///s, S. Miillei'. 



The general colour of this tiny squirrel on the upper 

 parts may be described as oli\'e-b:"own, but the head and the 

 back especially over the neck and shoulders, are moi-e or less 

 suffused with reddish, which, however, is not very prominent 

 nor contrasting much with the general colour. The muzzle 

 is yellowish, and there is a similar ring round the eye, but the 

 sides of the face from the moustache backwards, and the sides 

 of the neck resemble the sides of the body. The limbs also 

 are concolorous with the body. The under parts are whitish 

 or dusky, suffused, more or less, with rufous, and on the 

 scrotum of the males with bright orange. The hairs of the 

 tail have a broad basal band succeeded by a broad black band 

 which is tipped with yellowish ; the under surface of the tail 

 being rather brightly worked with orange. The ears are of 

 moderate size rounded, and clad with very short hairs. 

 The whiskers are black. Nearly one half of the sule of the 

 hind foot is clad. 



The iris is brown; and the u[iper incisors are very pale 

 yellow; th:i lower pair are nearly white. The skull is much 

 arched behind ; the facial portion is very broad at the base, 

 becoming pointed towards t!ie front, and moderatelv long. 



This species is ft)und in Borneo, Sumatra, and Malacca. 

 Its native name is'pukong'; it is common all througli the 

 low country, ascending the mountains to the height of 

 2000-ft. Like S. soriciims and S. ivlu'tclicadf it is usually 

 seen running round the branches and trunks of trees making 

 a curious little sqeaking noise with each movement, and whisk- 

 ing its tiny tail about with an air of importance.

This species is allied and very similar to S. cxi/is, Miill., 

 but slightly larger, and with the ears, instead of being rounded 

 and short haired, narrow, pointed, and with beautiful long 

 black-and-white pencils of hair, nearly as long as the head, and
