HORN EXPEDITION—MAMMALIA. 
31 
The ears, wlien laid foi’ward, reach (in spirit specimens) at least half way 
between the anterior end of the eye and the tip of the snout. 
The tail varies in length, but is relatively longer than the specimen of which 
measurements are given in the British Museum Catalogue and than that of 
mature specimens from the coastal district. It is incrassated and light grey in 
colour all over, the ventral being little, if any, lighter in colour than the dorsal 
surface. 
The following are the dimensions of eight of the specimens :—

In specimen a ten mamnue are present, to four of which young ones are 
attached. 
In specimen b ten mamnue are present, to five of which embryos are attached. 
In specimen c ten mamma3 are present. 
In specimen d only six mammae can be seen, though the animal is mature; 
these correspond to the anterior three of each side present in the other specimens. 
Except in regard to this point the specimen is closely similar to the others, and 
evidently belongs to the same species. It was captured at Charlotte Waters on 
the same sandy plains in which specimens a, and c were caught. 
In specimen_/ten mammae are present, two on one side and four on the other, 
having embryos attached. Specimens with end^ryos attached to the teats were 
captured in November and December, which are evidently breeding months. 
Specimen h* did not come from Central Australia, and its measurements are 
inserted for comparison with those from the latter district. It will be seen that 
the tail is proportionately shorter. With the exception of this example, all the
