Notomys fuscus

The dusky hopping mouse (Notomys fuscus) is an Australian native rodent specialised for the deep desert. Like all hopping mice it has strong front teeth, a long tail, dark eyes, big ears, well-developed haunches and very long, narrow hind feet. It weighs between 20 and 50 g (0.71 and 1.76 oz). (Compare with the common house mouse, at 10 to 25 g (0.35 to 0.88 oz).)
