POLYPODIACE^. 
Caernakvonshire. — On nearly all the Caernarvonshire hills 
this fern appears in small quantities, and occupies a considerable 
range as regards elevation : it occurs in the interstices of stone 
walls, between the lakes of Llanberis and the town of Caernar- 
von, at a very slight elevation above the level of the sea, and 
ascends to the very summit of Snowdon, Glyder, and the neigh- 
bouring heights, 3500 feet and upwards. 
Cheshire. — We find it recorded in the ^Botanist’s Guide,’ 
on the authority of Mr. Bradbury, as occurring on the top of 
Tag’s Ness, a hill near Macclesfield.

fern, in some abundance, on the slate mountains of Cumberland.
