and the north of England. There is, however, a tradition of 

 its former existence in the fens of Norfolk ; it was reported 

 nearly half a century ago as common in Worcestershire, and

 shire, Yorkshire, and Westmoreland, and in Scotland in the 

 Edinburgh district, and Perthshire. Abroad it is well dis- 

 tributed in Norway and other parts of northern Europe, the 

 Alps, the mountains of Germany and Galicia, and in 

 Armenia.
