tailj 25^ inches; heel to end of toes^ 11 inches; ear 

 to tip of muzzle, 8 inches; length of ear, 3 inches 7 

 lines. The female measures from the tip of the nose 

 to the root of the tail, 33 inches ; tail, 26 inches ; 

 tarsus, 10 inches 2 lines. These dimensions are

 can only be regarded as approximations. The total 

 length of the animals in all probability should be 

 rather more than here mentioned.
