Chapman's pebble-mound mouse lives in dry grassland in Western Australia's Pilbara region. It builds mounds from small stones on the ground.
Its back and sides are fawn-colored, with a darker head. The paws, throat, and belly are cream to white.
It eats seeds of native grasses and shrubs, other plant material, and small insects. It gathers stones into a mound above ground, with an entrance into the nest.
