Profile last updated: 07 Sep 2017


Gould's mouse (Pseudomys gouldii) lived in eastern inland Australia, and was named after John Gould's wife, Elizabeth. It was slightly smaller than a black rat, and quite social, living in small family groups that sheltered by day in a nest of soft, dry grass in a burrow. It usually dug burrows at a depth of 15 cm under bushes.

Gould's mouse was common and widespread before European settlement, but disappeared rapidly after the 1840s, perhaps being exterminated by cats. Alternatively, it may have been out-competed by the introduced rats and mice, succumbed to introduced diseases or been affected by grazing stock and changed fire regimes. The last specimens were collected in 1856–57, and it is presumed to be extinct.


Sightings of live animals and reports of subfossil remains indicate that Gould's Mouse was formerly distributed throughout south-west Western Australia, eastern South Australia and New South Wales.

Habitat and ecology

  • Little is known of Gould's Mouse. The species is reported to have preferred sandhills and plains, and to make burrows under bushes in loose soil.
