 numbers, especially that of Galtres, in the vale of York. 

 Its tusks are very frequently found there and in the alluvial 

 deposits of Holderness. The direct testimony as to the 

 existence of wild boars is weaker and less voluminous than

 other kinds — etymological and legendary — suffices to war- 

 rant us in regarding it as formerly common in the county. 



Fam. CERVIDiE. 



56. Cervus elaphus L. Red Deer. 



Semi-domesticated, only in parks. Formerly wild, ranging 

 over the whole county. Have been for centuries kept in 

 Wharncliffe Chase and in Bolton Deer Park; and in these 

 localities are, in all probability, the lineal descendants of
