PACIFIC SCIENCE, VoL VIII, October, 1954 
LOCAL DISTRIBUTION: Sta. 10 (11342). 
My plants appear to agree with this little- 
known species according to Yamada’s treat- 
ment of it, but it has not been possible to 
compare with any east Atlantic specimens. 
The type is presumed lost.

LOCAL DISTRIBUTION: Two small plants 
found creeping on a coral fragment, Sta. 7 
(11249). 
Chondria baileyana (Mont.) Harvey 1853:

LOCAL DISTRIBUTION: Dredged from 2-4 
m., Sta. 2 (11297); dredged from 5-7 m. off 
north end of lie de Tre (11276). 
The specimens at hand are small and in 
part fragmentary, but seem to agree with this 
species in diameter, branching, branch shape, 
cortex, and tetraspore production. They cor- 
respond well, except for stature, with spec- 
imens distributed as No. 43 in Phyc. Bor. 
Amer.

LOCAL DISTRIBUTION: Attached to a piece 
of coral dredged in 2-3 m., Sta. 2 (11372); 
on coral rocks at —0.5 foot tide level, Sta. 
1 (11130). 
These two collections, one sterile and one 
tetrasporic, are in excellent agreement with 
Dangeard’s African plant. In the sterile ex- 
ample shown in (Figure 62/ branch primor- 
dia are present in small pits on the thallus 
surface, while in the tetrasporic examples 
these have grown out into short branchlets 
as shown in Dangeard’s figures. 
The flat thallus with pinnate primary 
branching is characteristic.
