HORN EXPEDITION—MAMMALIA. 
The tail is considerably more than half as long as the body, with a terminal 
crest which, on the dorsal side, commences at about 70 mm. from the tip. At first 
the hairs of the crest are of a dark brown colour, but at the tip, where they 
measure 22 mm. in length, they are white. On the ventral surface there is also a 
smaller crest of white hairs, commencing at about 30 mm. from the tip and 
reaching a length of 12 mm. 
The mamma? as described are eight in number.

Habitat .—The inland parts of Victoria and New South Wales, South and 
West Australia, and Central Australia. In the British Museum Catalogue the 
locality of Northern Territory is cjueried. There is no doubt but that the range of 
the animal extends widely over the central area. in the Adelaide Museum is a 
specimen from Barrow Creek, which lies well within the tropics, and throughout 
the whole of our expedition all the natives were well acquainted with it. My 
specimen was dug out of a hole in a sandy plain by a native black woman. Mr. 
Lydekker* has given an account of its habits derived from notes by Mitchell and 
Krefft. It appears to have been at one time fairly common in such parts as the 
Murray district, but is now very difficult to find, and is evidently rapidly 
becoming extinct, except perhaps in the more central districts. 
Chceropus is, again, one of the border-land forms of marsupials and not found 
in the Euronotian region. 
Note .—In August I received from Mr. Byrne a female with two well-developed 
young in the pouch. These, judging from their .size, must have been born not less 
than a month, probably the breeding-time was near to the end of June, though the 
date most likely varies to a certain extent with the nature of the seasons. This 
specimen was captured at Charlotte Waters, and is of considerably darker colour 
than the one described above.
