The regions which these animals inhabit are lonely and barren, with but very 
small amount of vegetation. In such places there are numerous perpendicular 
faces of rock, up and down which these tiny creatures dart with such hghtning-

by no means shy, the report of a gun is sufficient to send them at once to their 
holes; and a spot which at one moment may be seen covered with hundreds of 
these creatures, will be left deserted in an instant. The natives hunt them with

large quantities are annually imported.

about 16 to 20 inches, and that of the tail, exclusive of the hair at the tip,
