SEA-WEEDS. 201 



Thebroad, shallow, half-tide pools afford Anthea cereus 

 of the grey variety, Actinia mesembryanthemum, and 

 A. crassicornis ; and in the latter part of summer 

 Padina pavonia grows in them. Those parts of the 

 ledges that are uncovered only at the lowest tides, 

 yield the green-tentacled and crimson-tipped variety 

 of Anthea, very brilliant tmd silky, and in great pro- 

 fusion ; and among the sea-weeds, two or three kinds 

 of Cladophora, Corallina, and Jania, thick tufts of 

 Rhytiphlcea pinastroides, and some Polysiphonite and 

 Gallithamnia. 



After we have passed along for some distance, the 

 cliffs begin to grow more lofty, and more solid and 

 rocky in their character ; the pools disappear, and the 

 ledges become more rough, and more indented with 

 deep narrow fissures, until they terminate in an ab- 

 rupt wall or quay, which protects a tiny mimic bay. 

 This little indentation is a most prolific source of 

 washed sea-weeds in the summer and autumn, and 

 many specimens of rarity and beauty are gathered 

 here. The rich and brilliant Rhodymenia laciniata is 

 not uncommon, and the more delicate and scarcely less 

 heaatiial Nitophyllumpunctafum (See Plate V.), with 

 Delesseria sanguinea and sinuosa, and many other 

 species equally attractive, occur. Some of these are it 

 is true deep-water kinds, washed in by the tides ; the 

 first named, for example, I have never met with in a 

 growing state ; but this little bay is particularly rich 

 in littoral species. At the bottom of the wall or 

 quay-like edge, grow several fine tufts of those very 

 elegant Algse, Griffithsia corallina, and G. setacea ; 

 Ceramium eehionotum (See Plate VI.) and G. cilia-
