ENTEROMORPHA PROLIFERA (O. F. Miill.) J. Ag. C, 526, 527. 
CLADOPHORA sp. , 528. 
Bryopsis pLUMOSA (Huds.) Ag. P, 293; C, 531. 
CODIUM FRAGILE (Sur.) Hariot. P, 285; C, 529. Codium muc- 
ronatum of Cowdry’s list. Setchell and Gardner (Univ. 
California Publ. 8: 171. 1920) have recently reduced the 
more widely recognized Codium mucronatum J. Ag. to the 
position of a synonym of C. fragile, the type of which was 
Japanese. Codium mucronatum was originally described 
with three named forms (no specified or implied type) from 
Tasmania, Alaska, California, New Zealand, and Chatham 
Island. 
PHAEOPHYCEAE

SCYTOSIPHON LoMENTARIA (Lyngb.) J. Ag. P, 286; C, 550.

LEATHESIA DIFFORMIS (L.) Aresch. C, 550 p.p., a minute form,

making cushions 5-8 mm. broad. 
CHORDARIA FIRMA Gepp. P, 288a; C, 538, in rock pools. 
Chordaria Chordaria (Harv.) comb. nov. Cladosiphon Chor-

attached to Chorda Filum. 
The plants are 8-12 cm. tall and are more slender and 
smaller in every way than in the type (from Port Phillip, 
Australia) figured by Harvey, who says that specimens from 
Georgetown, Tasmania, are ‘very much larger and more 
robust than our figure.’’ Kiitzing’s figure is based upon a 
plant from Port Fairy, Victoria, and is somewhat similar to 
Harvey’s. Okamura has referred the present number to 
Chordaria Cladosiphon Kiitz. (in herb. Cowdry) and it is 
apparently this that bears that name in Cowdry’s Pei-tai-ho 
list, although the label in the Cowdry herbarium indicates 
that the plant really came from Chefoo. Collins also has 
listed the same species from Pei-tai-ho.
