MAOBOFOSID^. 



Hah. South-eastern South Australia, Victoria and Tasmania. 



Type in the Paris Museum. 



M. billardieri is the common small Wallaby of Victoria and 

 Tasmania, where it is excessively abundant. It has been very 

 often confused with the next species, the specimens of it in many 

 museums and zoological gardens being labelled as M. hrachyurus, 

 which it resembles in its general colour and proportions, but which 

 it exceeds very considerably in size, to say nothing of the very 

 obvious differences between the two species in cranial and dental 

 characters. 



The length of the molars in this species is very remarkably con- 

 stant, as in all the twelve specimens measured the combined 

 lengths of ms.^-^ falls between 16-5 and 17*1 millim., a range of 

 only 0-6 miUim.
