SCIUEUS. 263 



A specimen from Malacca differs from all the others in the yellowish-brown 

 colour of the upper parts generally ; and in the red tint of the thighs being but 

 little pronounced and tending more to yellow than red ; the under parts are pure 

 white. 



Length, from muzzle to tail 7 '50 inches ; tail reaching forwards to nearly the 

 head. 



The skull has a rather narrow and pointed facial portion, and no great breadth 

 between the orbits. 



In S, insignis the two wrist-pads are largely developed, especially the inner of 

 the two, which is enlarged internally by a peculiar development, as it were, of the 

 metacarpal of the thumb, which projects outwards ; and the other bones of the digit 

 appear as if they were bent inwards on themselves, towards the front end of the pad, 

 acting as a kind of support to it. The small nail is flat and placed near the end of 

 this hook. I have not observed a similar arrangement in any other squirrel. But 

 in all the Southern Asiatic species the thumb can always be detected, generally, 

 with a small flattened nail ; but in some species, such as S. palmaruniy it is most 

 rudimentary. 



This species occurs in Sumatra, Java, Borneo, and has also been found at Canton. 

 In these islands it is essentially an inhabitant of the mountains, and is seldom found 

 upon trees. Miiller and Schlegel observe that it builds its nest in the trunks of 

 fallen trees.

This small lineated squirrel, with white pencils to its ears, has the general colour 

 of the fur olive-brown, each ban- having a dark brown or nearly blackish tip, with a 

 sub-apical yellow band, the base of the hair being slaty black. A pale, yellowish band 

 commences in the types of S. maclellandi, S. pembertoni, and S. barbel on the side 

 of the nose, and passing underneath the eye and ear along the side of the neck, is
