hunts in companies ; and when these long-bodied 
creatures sit up erect, glaring with beady eyes, 
grinning and chattering at the passer-by, they look 
like little friars in black robes and grey cowls; but 
the expression on their round faces is malignant 
and bloodthirsty beyond anything in nature, and 
it would perhaps be more decent to ken them to

find few to quarrel with his doctrine. 
Of Edentates there are four. The giant armadillo 
does not range so far, and the delicate little pink

and wedge-shaped tail admirably fitting imto the 
deep-cut shell side by side; and the quirquincho 
(Dasypus minutus), all inhabit the pampa, are
