MARINE ALG^S OF VANCOUVER ISLAND 
127 
Rhodqchorton rothii (Turton) Nageli. Setchell & Gard- 
ner, 1903, p. 347; Harvey, 1853, p. 242, as Callithamnion rothii; 
P. B.-A., No. 49. Victoria, Gardner. 
Gloiopeltis furcata (Post. & Rupr.) J. G. Agardh. Set- 
cheil & Gardner, 1903, p.348; Harvey, 1853, p. 183; P. B.-A., 
No. 945. Port Renfrew, Butler & Policy. 
Gloiosiphonia capxllaris (Huds.) Carmichael. Harvey, 
1853, p. 202; P. B.-A,, Nos. 849, 1700. Departure bay, Am- 
phitrite point, Comox, Macoun; Esquimalt, Harvey. The 
plants collected by Macoun from these stations agree with each 
other and with the Atlantic plant; this confirms Harvey's 
record, which was heretofore the only one for the Pacific. 
G. caUfornica (Farl.) J. G. Agardh, common from Washington 
to southern California, has not been reported from Vancouver 
island. 
G. verticillaris Farlow. Setchell & Gardner, 1903, p. 348; 
P. B.-A., No. 100; Tilden, Centuries, No. 205. Port Renfrew, 
Tilden. To this species should probably be referred Halymenia 
ligulata, from Esquimalt, of Harvey's Lyall paper. 
Aeodes nitidissima J. G. Agardh. Setchell & Gardner, 1903, 
p. 349 ; P. B.-A., No. 946. (121). Amphitrite point, Ucluelet. 
Macoun, a single specimen only. 
Gratelotjpia cuTLERiiE (Binder) J. G. Agardh. Setchell & 
Gardner, 1903, p. 349; P. B.-A., No. XCIX; Tilden, Centuries, 
No. 304. Victoria, Comox, Macoun; Esquimalt, Tilden, 
G. pinnata (Post. & Rupr.) Setchell in P. B.-A., No. 947; 
Setchell & Gardner, 1903, p. 349. Port Renfrew, Butler & Polley. 
Prionitis lanceolata Harvey, 1853, p. 197 ; Setchell & Gard- 
ner, 1903, p. 352; P. B.-A., No. 199. This species passes insen- 
sibly into the following, and most of the material from Van- 
couver island called P. lanceolata belongs under the narrow 
pinnate form of P. lyallii. A few specimens, from Victoria, 
Macoun, agree with P. lanceolata of more southern regions. 
P. lyallii Harvey, 1862, p. 173; Setchell & Gardner, 1903, 
p. 350. An extremely variable plant, as may be seen by the 
numerous forms recorded by Harvey and by Setchell & Gardner. 
What appears to be the typical form, 
Forma normalis Setchell & Gardner, 1903, p. 350, was col- 
lected at Victoria, Departure bay, Macoun.
