than is the case with the Potoroo. 

 Uuiler (1961) notes that head 

 length is slightly greater in the male 



potoroo. 



PotOIVUS tridaclyloitx Kerr. 



I- ewer dead animals of the Pot- 

 OrOO have been encountered. It is 

 thought that this is due to the animal 

 living in less accessible places. 



Ihe Potoroo is similar in general 

 appearance to the Bettong but is 

 much more ohese and hence is not 

 so graceful. The tail has no crest 

 and" the white tip is longer enabling 

 it to be seen at a distance. Wood 

 Jones (1924) describes a uniform 

 darkening to black at the tip of the 

 tail. He seems to regard a while tip 

 as rare. He gives eye colour as brown. 



The fur is grey-brown to brown, 

 rather variable throughout the popu- 

 lation, hut not apparently over a 

 wide range. An old male was found 

 dead probably within the previous 

 twenty-four hours. 



Fur dense, long, soft, giey brown 

 on dorsal surface, paler hi own later- 

 ally, smoky grey ventially. T

 black hairs for 140 mm., then dirty

 grey at base, then white, but often 

 with brown or black tip. Ears dark
