5. Frond coarse, stout, branches mostly short and blunt. 5. G. Wrightii. 

 5. Frond less stout; many short, acute branches. 6. 



6. Branching corymbose; short acute branches near summit. 



4. G. damaecornis. 



6. Short acute branches throughout. 7. 



7. Frond pyramidal, branchlets dense, erect. 2. G. ferox. 



7. Frond irregular, delicate, branches scattered, patent. 3. G. divaricata. 



1. G. CONFERVOIDES (L.) Greville, 1830, p. 121; Harvey, 1846-51, 

 PI. LXV; Fucus confervoides Linnaeus, 1763, p. 1629. Kemp, a 

 single plant of typical character; another specimen, marked G. com- 

 prcssa, is probably also G. confervoides. 



2. G. FEROX J. G. Agardh, 1851, p. 592; 1876, p. 414; P. B.-A., 

 No. 1932. Faxon; In shallow water, Moseley; Kemp; Rein, as G. 

 armata; Dingle Bay, Inlet, Heron Bay, Jan., Grasmere, March, 

 Hervey; Grasmere, Aug., Collins. Several species of the general 

 appearance of G. ferox have been described, and it is by no means 

 easy to separate them. There is a good deal of variety in the Bermuda 

 forms we have included under this name, but they seem to agree in 

 the terete but apparently distichously branched frond, with short 

 acute branches, subsecundly placed. We have found it quite com- 

 mon in warm shallow water, such as the lagoons near Grasmere and 

 Fairyland. 



3. G. DIVARICATA Harvey, 1853, p. 109. Mrs. S. A. Boggs; 

 Bailey's Bay, Feb., Wadsworth; reported by Kemp, but no specimen 

 found in his herbarium. The two specimens we have seen agree 

 well w r ith Harvey's description, and there seems no other place for 

 them. The habit is much like that of Ocktodes filiformis J. Ag., and 

 the latter species, from Jamaica, was erroneously distributed as G. 

 divaricata in P. B.-A., No. 789. The Ochtodes has an articulated fila- 

 mentous axis which is not found in Gracilaria. 



4. G. DAMAECORNIS J. G. Agardh, 1851, p. 597; 1876, p. 415. In 

 shallow water, Grasmere, Aug., Collins; Miss Wilkinson. As we 

 understand this species, it is stouter than G. ferox, drying very hard 

 and firm; the branching is more regularly dichotomous, the ramuli 

 short and subulate, near the ends of the branches. We have found 

 it once only, when it grew among G. ferox, but could be distinguished 

 from the latter by its appearance, even as seen from the boat. 



5. G. WRIGHTII (Turn.) J. G. Agardh, 1851, p. 599; Fucus Wrightii 

 Turner, 1811, PI. CXLVIII; including G. Poitei J. G. Agardh, 1851, 

 p. 596 and G. cornea J. G. Agardh, 1851, p. 598. Castle Harbor, 

 Feb., Farlow; Elbow Bay, Dec., Collins. We have carefully examined
