“Wallaby” of the Colonists of Tasmania, to which island 
it 1s restricted. 
I cannot trace that this animal is in any way gregarious, as 
stated by Mr. Gould, in his ‘ Macropodide.” They are, it 
is true, very numerous in many localities; but not, I think, 
really gregarious. I have had four of them many months 
past in an enclosure at Penquite, and I perceive that they 
all adopt separate hiding-places, considerably apart, during 
the day. 
The Wallaby often inhabits our dense Myrtle (Fagus) 
forests; and as no gramineous plants grow in them, I presume 
it must occasionally live upon the roots of ferns, fungi, &c., 
as indeed I am assured it does.
