Cladophora inserta var. ungulata (Brand) 
Setchell 1926: 75, pL 22, fig. 1; B^rgesen 
1948: 8, fig. 2. Cladophora mauritiana var. 
ungulata Brand 1904: 180, pi. 5, figs. 10, 11 
(Hawaii) 
LOCAL distribution: Epiphytic as tufts to 
2.4 cm. high on saxicolous red algae, Sta. 6 
(11232); small and poorly developed on in- 
tertidal rocks, Sta. 2 (11083). 
Cladophora patentiramea forma longiar- 
ticulata Reinbold, in Weber van Bosse 
1913: 84 (Indonesia; type of the species 
from Tahiti); B0rgesen 1940: 36, fig. 12a-e 
Fig. le 
LOCAL DISTRIBUTION: Forming a low, loose 
mat on intertidal rocks, Sta, 11 (11413). 
Eotocladia viridis Reinke 1879: 476, pL 6, 
figs. 6-9 (Naples, Italy); Kylin 1949: 38, 
39 Kg. 7/ 
LOCAL DISTRIBUTION: Abundant in the cell ' 
wall of Cladophoropsis herpestka from Sta, 4 
(11197a). 
Halicystis pyriformis Levring 1941: 612, 
fig. 3L-P (Juan Fernandez Islands) 
Fig. ^a-c 
LOCAL DISTRIBUTION: Attached to crustose 
corallines on old coral dredged from 2-3 m., 
Sta. 2 (11382). 
The several plants at hand, the largest about 
2.2 mm. high, are in excellent agreement with 
Levring’s species. The chromatophores are 
like those of the type but average smaller, 
mostly 4-5 m in diameter. My plants are ap- 
parently young, corresponding with his fig- 
ures 3M-N. 
Valonia ventricosa J. Agardh 1887: 96 (St. 
Croix, Virgin Islands); Okamura 1936: 32, 
fig. 13; Egerod 1952, pL 29, fig. a 
Fig. Se 
LOCAL DISTRIBUTION: Occasional, attached 
to lower parts of coral masses dredged in 2-3 
m., Sta. 2 (11370). These are of rather small 
size, mostly 1 cm. in diameter or less, and 
tend to occur in somewhat clustered groups. 
Valonia aegagropila C. Agardh 1822: 429 
(Venice, Italy); Egerod 1952: 348, pL 29, 
“S' “ F» 8/ 
LOCAL DISTRIBUTION: Forming small mats 
on rocks, Sta. 4 (11155); forming extensive, 
succulent mats dominating rock surfaces at 
about + 0. 5-1.0 foot tide level, Sta. 11 
(11355). 
Boergesenia forbesii (Harv.) Feldmann 
1938: 588, figs. 3-5; Yamada 1950: 174. 
Valonia forbesii 1859^: 333 (Ceylon) 
Fig. ^d 
LOCAL DISTRIBUTION: Occasional on inter- 
tidal rocks subject to gentle surf, Sta. 11 
(11411). These plants are identical with those 
illustrated by Tseng (1936b) from nearby 
Hainan Island. 
Dictyosphaeria versluysii Weber van Bosse 
1905: 144 (Indonesia) 
Fig. 8^, / 
LOCAL DISTRIBUTION: On coral rocks, Sta. 
1 ( 11126 ). 
These plants are rather small compared to 
D. versluysii from some other areas, and their 
segments are smaller, but it appears unwise in 
this account to attempt to assign them to 
D. vanbosseae, D. setchellii, or D. australis, all 
of which seem unsatisfactorily distinguished 
from D. versluysii. 
Dictyosphaeria cavernosa (Forsk.) B0r- 
gesen 1932^: 2, pi. 1, fig. 1. Viva cavernosa
