Habitat .—Central Australia, Alice Springs. The animal is terrestrial, living 
in holes amongst rocks and under stones. 
The first specimen was secured by Mounted-trooper South, of Alice Springs, 
and by him presented to Dr. Stirling, for whom it had been intended. Dr. 
Stirling kindly handed it over to me for description, as officer in charge of the 
zoological department of the expedition. 
Subsequently, whilst staying at the Alice Springs, I was able, through the 
kindness of Mr. F. J. Gillen, to secure two more specimens, both of them females. 
The animal is evidently in the main terrestrial, being captured by the blacks 
(two specimens also were caught by cats) in holes amongst stones.
