36 MAMMALIA GLIRES. [LEPUS. 



of the tail two inches six lines ; of the fore leg, from the olecranon to the 

 end of the toe-nails, seven inches three lines; of the hind foot, from heel 

 to toe, six inches. 



DESCRIPT. In general somewhat smaller than the Common Hare, with 

 shorter ears and more slender legs : tail shorter. Fur in summer grayish 

 tawny mixed with black, here and there inclining to ash-colour; in 

 winter wholly white, with the exception of the tips of the ears, which 

 remain always hlack. 



Inhabits the Scotch mountains : keeps near the summits, and never 

 descends into the valleys, or mixes with the common species. Change of 

 dress effected in the months of September and April; caused by an 

 actual change of colour in the hair itself, without the shedding of the 

 fur. Obs. The L. variabilis of Pallas is probably a distinct species.

DESCRIPT. Varying extremely in the domesticated state in size and colour, as 

 well as in the form and direction of the horns, which last are sometimes wholly 

 wanting. A wild breed, (Bewick, Quad. p. 38.) formerly met with in Scotland, 

 but now extinct, said to have been characterized by their white colour, with the 

 muzzle and ears black. 



Is capable of breeding at the age of two years. Goes nine months with young, 

 and produces one, rarely two, at a time. The two central incisors are shed in the 

 tenth month ; the adjoining ones in the sixteenth ; by the end of the third year the 

 change is wholly completed.
