(as in the last family), but the great toe is represented by a 
small tubercle, while the cutting teeth are -J, growing from 
persistent pulp through life, as in the rats, squirrels, and 
guinea-pigs (fig. 9). 
We may now pass to a very different family of animals 
belonging to the kangaroo’s order. We pass, namely, to the 
Dasyuriclce , or family of the native-cat, wolf, and devil, so

Dasynrus , which gives its name to the family) may be taken 
as a type ; but two others merit notice. 
The first of these is Myrmecobius , from Western Australia,

geographical and zoological relations, to be shortly referred to. 
With respect to this creature, Mr. Gilbert has told us —
