Habitat .—Alice Springs, Central Australia, June, 1895. 
This specimen is an adult female, and was suckling at the time of capture. 
The great length of the tail, the size of the ears, and the small hind foot-pads are 
points which should assist in identifying the species. It is to be hoped that 
further examples will be obtained when the cranial characters can be recorded and 
the foregoing description amplihed if necessary.
