Type, in the National Museum, Melbourne. 



The native name at Alice Springs is Mulgaruquirra, and at 

 Charlotte Waters is Iwurra. 



With regard to its habits Mr. Gillen says "the Mulgaruquirra 

 scoops out a shallow hole on the surface of the ground just 

 sufficiently large to lie in and thatches it with grass ; habits 

 nocturnal." 



Mr. Byrne says: — "The Iwurra and Tubaija (Charopus 

 castanotis) are almost identical in their habits, and build similar 

 nests of grass and twigs in shallow oval hollows scooped out in 

 the ground. They are captured in the same way, viz., by placing 

 one foot on the nest, pinning the animal down and then pulling 

 him out with the hand." 



Locality. — Burt Plain north of Alice Springs, and sand-hills 

 about forty miles to the north-east of Charlotte Waters.
