Habitat. — Central Australia, near Lake Amadeus. Terrestrial. 



Our attention was drawn to the first specimen seen, by 

 Mounted Trooper Cowle as we were riding over sand-hills 

 covered with tussocks of porcupine grass (Triodia irritaiis). It 

 ran about from tussock to tussock. A second specimen was seen 

 in the same district but not captured, and Mr Cowle has since 

 informed me that he has seen the same animal near Illanmrta in 

 the James Range.
