PETROGALE XANTHOPUS, Gould, 
Yellow-footed Rock- Wallaby. 
A SINGLE Figure of the entire Animal, of the size of life. 
Two reasons have induced me to give double figures of this animal — one to show its 
peculiar brushy tail and richly coloured ears, of the size of life, while, in the scenery 
accompanying the reduced figures, I have endeavoured to portray the kind of country 
inhabited by this new and very fine species. It was one of the last discoveries made 
by one who sacrificed his life in the pursuit of natural history on the east coast of Aus- 
tralia ; and it would have been well if the name of Frederick Strange had been associated 
with the species. Dr. Gray has, however, seized upon a good specific character in the 
name of /nanthopus, which will for ever serve to distinguish this fine species of the 
genus Petrogale.
