the tail nearly equal to the head and body in length; the tarsi very 
slender; the fur very long and soft, and its general hue pale ashy 
grey ; on the hinder part of the back a slight brownish tint, produced 
by a very fine and indistinct pencilling of dusky or pale greyish yel- 
low; the lower part of the sides of the body and the whole of the 
under parts white, but not quite pure, having a faint greyish hue ; the 
head grey-white, pencilled with black ; the sides of the muzzle white ; 
the ears well-clothed with minute greyish white hairs ; the feet white,

This animal is remarkable for the extreme softness and delicate 
colouring of its fur, which on both the upper and under parts of the 
body is of a slate-grey tint next the skin, but on the under parts of a 
pure white colour externally, except on the mesial line of the abdo- 
men, where there is a slight yellow tint; on the upper parts and 
sides of the body the exposed portions of the hairs are of a delieate 
ochreous yellow, but on the back there is a considerable admixture 
of black, the points of the hairs being of that colour ; ears rather large 
and nearly of an oval form, tolerably well-clothed with small hairs, 
of a white colour, excepting on the fore-part of the outer surface, 
where they assume a dusky greyish hue; tail nearly equal in length 
to the body, tolerably well-clothed with hairs, but not so thickly as 
to hide the scales ; these hairs, though short, are longer, more nume- 
rous and much less harsh than is usual in the true Rats; on the sides 
and under part of the tail they are pure white, and on the upper 
surface some are white and others blackish, but chiefly white on the 
apical portion ; sides of the muzzle white; hairs of the moustaches 
moderate, black at the root, but greyish at the point.
