6. C. taxifolia (Vahl) Agardh, 1822, p. 435; Weber, L898, p. 292; 

 Borgesen, 1907, p. 363, figs. 9-10; 1913, p. 131, figs. 104-10.'); Collins, 

 1909, p. Ill; Fucus taxifolius Vahl, L802, p. 36. Farlow; Walsing- 

 ham, a single plant, Hervey. Apparently rare, but may have been 

 mistaken for the commoner C. crassifolia or C. sertularioides, from 

 both of which it can he distinguished by the opposite, sickle-shaped, 

 narrow pinnules, with contracted base. 



7. C. sertularioides (Gmel.) Howe, 1905a, p. 570; Collins, 

 1909, p. 414; Fueus sertularioides Gmelin, 1768, p. 151, PI. XV, fig. 1. 



Forma longiseta (J. Ag.) Svedelius, 1906, p. 114, fig. 10; Collins, 

 1909, p. 415; P. B.-A., No. 1873; C. plumaris forma longiseta Weber, 

 1898, p. 295. Harrington Sound, Oct., Hervey; Cliff Tool, April, 

 Collins. 



Forma BREVIPES (J. Ag.) Svedelius, 1906, p. 114, fig. 7; Collins, 

 1909, p. 415; C. plumaris forma brevipes Weber, 1898, p. 294. Wal- 

 singham, March, Hervey; Ely's Harbor, July, Collins. 



8. C. peltata (Turn.) Lamouroux, 1809* p. 332; 1809c, p. 145, PL 

 III, fig. 2; Weber, 1898, p. 373, PL XXXI, figs. 9-11; Collins, 1909, p. 

 421 ; Fucus chemnitzia var. peltatus Turner, 1819, p. 8, PL CC. Faxon, 

 a single quite typical specimen; Bethel's Island, Dec, Collins. 



9. C. racemosa (Forsk.) J. G. Agardh, 1872, p. 35; Weber, 1898, 

 p. 357, PL XXXI, figs. 5-8; XXXII, figs. 1-7; Collins, 1909, p. 419; 

 Fucus racemosus Forskal, 1775, p. 191. A very variable species, 

 with no acknowledged typical form, apart from the many forms and 

 varieties into which it has been divided. It is uncertain to which of 

 these should be referred the C. clamfera of Rein and Moseley. 



Var. clavifera (Turn.) Weber, 1898, p. 361: Vickers, 1908, p. 28, 

 PL XLV; Collins, 1909, p. 420; Fucus clamfer Turner, 1808, PL 

 LXXVII. Harrington Sound, March, Wadsworth, No. 71; Hamil- 

 ton, Farlow; these are the only records of the typical form of this 

 variety, but forms between this and vars. uvifera and laetevirens are 

 not uncommon. 



Var. uvifera (Turn.) J. G. Agardh, 1S72, p. 35; Weber, 1S98, p

Var. occidentals (J. Ag.) Borgesen, 1907, p. 379, figs. 2s 29 

 1913, p. 152, fig. 124; Collins, 1909, p. 420; P. B.-A., No. 2021. C 

 chemnitzia var. occidentalis J. G. Agardh, L872, p. 37; Walsingham 

 Jan., March, Tucker's Town, Feb., Dec., Hervey; Cliff Pool, Hungry 

 Bay, April, Hamilton Harbor, dredged down to 18 meters, Dec, 

 Collins. Agrees well with Borgesen's description and figures, and with
