DESCRIPTION. 
In size this species is smaller than the house mouse. I he uppei foie- 
teeth are slightly grooved. The head is short, the forehead arched, and 
the nose rather blunt. Eyes small, but prominent ; whiskers longer than 
the head. The ears are rather long, and have a very conspicuous incurva- 
tion of their anterior margins, which are fringed with hairs ; they are 
thickly clothed on both surfaces with very short hairs. The legs and feet 
are small and slender, hairy to the nails. The thumb is almost entirely 
composed of a short convex nail. The tail is long, clothed with short 
hairs, rounded in the living animal, but square when in a dried state. 
The fur, which is of moderate length, is thin, soft, and silky. 
COLOUR. 
The incisors are light yellow, tipped with black ; eyes black ; point 
of the nose, lips, chin, fore-feet, and nails, white. Whiskers dark brown. 
There is a narrow fawn-coloured ring around the eyes. Ears, legs, and 
tail light ashy brown. The fur on the back and sides is from the roots 
of an uniform light plumbeous colour ; the under surface is scarcely a 
shade lighter.
