Hab. Oakley Creek, Darling Downs, east coast of Australia. 
This species greatly resembles the Mus lineolatus, but differs in 
having the ears smaller, and clothed internally with dusky hairs in- 
stead of white; the incisor teeth rather broader; the tarsi smaller ; 
the fore-feet much smaller; the tail more sparingly clothed with 
hairs, which are of a less pure white on the under side, and the darker 
hairs of the upper surface extending somewhat on to the sides of 
the tail, and in not presenting that strongly-marked line of separa- 
tion between the colouring of the upper and under surface. The fur 
is rather less soft, less tinted with yellow on the upper parts, and 
more so on the sides of the body.
