a range of from about 1200 feet to upwards of 3000 feet (1100 
yards, Watson) above the sea. It descends to about 1500 feet 
above the sea in Yorkshire. Its southern ascertained limit occurs 
in North Wales, in the county of Carnarvon; and it is found again 
in Yorkshire and the Lake district, and more abundantly in the 
Highlands of Scotland, its northern reported limit being Ross-shire, 
Sutherlandshire and Orkney. In Ireland, though the habitats are 
not numerous, they are widely dispersed. There are dubious
