LOW-WATER MAKE. 97 



Tetraspores are also found on separate plants im- 

 mersed in the frond. 



Both Furcellaria and Polyides are found on rocks 

 and in tide-pools, frequently on the coast of England, 

 Ireland, and in the Channel Islands. 



G-KATELOTJPIA PILICIjS"A. 



(slender grateloupia.) 



A dark purple weed, not very much admired, with 

 small linear fronds, scarcely exceeding two inches, and 

 rare. 



It may more likely be found in bays where a small 

 streamlet runs into the sea. 



At Sidmouth, Exmouth, Ilfracombe, and Cornwall, 

 rather plentiful. 



IEIDEA EDULIS. 



This must long ago have attracted our attention. 

 A flat oval upright frond of dark red, often glittering 

 in the water with bluish and purplish tints, and still 

 more often ragged and eaten into holes by marine 

 animals, who luxuriate on its fronds. It is also eaten 

 by the fishermen in the south-west of England, who 

 pinch it with hot irons to make it taste like oysters. 

 In Scotland they roast it in the frying-pan ; but 

 seldom will you find it in its own pool without a 

 pretty little Sea-slug, or yellow Nerit, or purple 

 Troches, enjoying the pasture Grod has made for them.
