OlllKIUMI \T MOUNI ARAPIl.t-.S 



On i November, IWJ, a small 

 Jcposit of bones and debris was 

 lonml on a sheltered ledge of a clitf 

 ;il Mouni Arapiles in far-western Vic- 

 loria. In 'he deposit were several 

 typical rock-wallaby faecal pellets. 

 Ihcse were light grey in colour and 

 tfppetfed to have been preserved in 

 the deposit for at least several 

 decades. Associated hone material 

 included specimens of Conilunis 

 ulhipc* and fifeqdomys spp., which 

 evidently disappeared from W. Vic. 

 some time last century, as well BS 



of the introduced mouse (A/ia mm- 

 riilii.t) and rabbit (Ontiolaxux cuiti- 

 ruhn). 



riirlhcr search brought to light 

 about 25 similar roek-wallab\ Faeces, 

 located in crevices in other pans of 

 the cliff system. '1 he extensive broken 

 outcrop of Devonian sandstone which 

 comprises much of Mount Arapiles. 

 appears lo be ideal rock-wall, ihy 

 habitat, and the species probably 

 lived there until the general reduc- 

 tion in status of the species about 50 

 years ago. There is little doubt that 

 the species which occurred at Mount 

 Arapiles would have been the same 

 as thai in the Grampians and the 

 Hyaduk Caves.
