Howe: CHINESE MARINE ALGAE I4I 
The plant from Pei-tai-ho referred by Collins to P. ferulacea 
belongs here; perhaps also the poor specimen from the 
Kiautschou region referred doubtfully to this species by 
Reinbold. In Cowdry’s list the species is referred to 
genus only. No. 555, 0n rocks, may be a form of the present 
species, but the plant is usually corticated almost to the 
apices and it has more divaricate branches; it is possibly P. 
Stimpsoni Harv. 
SYMPHYOCLADIA GRACILIS (Mart.) Falkenb. P, 2095; C, 545 and 
960 p.p. 
RHODOMELA SUBFUSCA (Woodw.) Ag. C, 543, thrown up on a 
sandy shore. A single tetrasporic plant differing somewhat 
in habit from European and American plants, the difference 
due, perhaps, chiefly to the more curved and contorted tetra- 
sporic branchlets. Also several loose denuded basal frag- 
ments in a bundle of ‘“‘duplicates’’ supposed to have come 
from Pei-tai-ho. The species has been recorded from Chefoo 
by Cotton and from Wei-hai-wei by Gepp. 
DASYA PEDICELLATA Ag. Dasya elegans (Mart.) Ag. P, 297; 
C, 965. Rather small tetrasporic plants, 9-13 cm. long. 
Collins was the first to ascribe this species to China, basing 
the record on plants from Pei-tai-ho. Okamura, in the 
Cowdry list, refers the specimens doubtfully to Dasya 
punicea Menegh. 
CERAMIUM JAPONICUM Okam. P, May, 1919, without number; 
CC) 557; tetrasporic plant in rock pool, determined by 
Okamura. ae 
CERAMIUM BoyDENII Gepp. P, May, 1919, without number, 
cystocarpic; C, 966, p.p., thrown up on a sandy shore, 
tetrasporic. Type from Wei-hai-wei. The cystocarps, 
which seem to be hitherto undescribed, are mostly terminal 
on short lateral proliferations; they are subtended and more 
or less enclosed by a sort of calyx of 2-8 (usually 4-6) mostly 
incurved bracts. 
CERAMIUM RUBRUM (Huds.) Ag. P, 298 and jor; C, 542. Re- 
ported from Tsingtau by Reinbold 
GLOIOPELTIS COLIFORMIS Harv. C, 530, in small clumps on 
rocks, often ee at low tide. Plants about 2 cm. 
high, irregularly furcat 
GRATELOUPIA FILICINA (Wulf. ) Ag. C, 535 (tetr.) and 537 p.p.
