Hab. Common on rocks, stones, &c., in the sea. /3. Coast of Mo- 

 ray, Mr. Brodie, Mr. Borrer and Hook. 



From 4 — 6 inches long, of a blackish brown colour, bushy. In C. ni- 

 grescens, the branches are fewer and straighter ; I suspect, the 

 effect of injury. /3. is small, reddish and fibrillose at the extremity, 

 — probably only the young state of the plant. 



4. H. urceo/ata, filaments very much branched bushy, brancblets 

 short and s])reading, lower articulations much longer, upper 

 shorter than broad, capsules urceolate. Conferva urceolala.^

 From 4 to 6 — 8 inches long, very bushy, of a line deep pellucid red 



when fresh, blackish brown when dry.

 elongated, brancblets abbreviated remote subsiniple, articula-?

Hab. 8]iores of the Firth of Forth, near Kirkcaldy, Mr. Greinlle. 



Mr. Dillwyn says " this is intermediate between the fucoides and nrceo- 

 lafa, from both of which it may be distinguished by its articulations^ 

 which are nearly of the same length throughout." If that be the case, 

 it cannot be the //. badid of Agardh (who indeed quotes Dillwyn^ 

 the original authority for the name, doubtfully) ; for he expressly 

 says, that tlie lower articulations are twice as short as they are broad, 

 and that the upper ones are thrice as long; and he compares his 

 plant with //. siricta, from which he tells us it difl'ers in colour. 



G. H. siricta, filaments branched nearly equal slender fastigiate 

 purplish red, branches dichotomous nearly erect, articulations 

 about thrice as long as they are broad, jlg.p. 56^. Conferva 

 stricia, Dillw. Corf Syn. p. 83. 



Hab. Rocks, Szc, in the Firth of Forth, near Kirkcaldy, Mr. Greinlle. 



About 4 — 5 inches long, remarkable for its slender straight twiggy 

 branches, long joints, and fine colour. 



7. H. Brodicei, filaments very much branched purpli.sh black, 

 branches elongate, brancblets scattered patent fascicidatcd 

 multifid, articulations of the main branches obsolete, those of 

 the brancblets about half as long again as broad. Conferva
