CODIACEAE 
Chlorodesmis Harvey & Bailey, 1851 
Clolorodesmis comosa Harv. and Bail. 
Philippines. Luzon I.: Pangasinan Pr., Ala- 
minos, Fenix, x 28. 
Chlorodesmis hildebrandtii A. and E.S. Gepp 
Philippines. Sulu Pr.; Sibutu I., Abbott, 19 
ii 57 (bish). Marianas islands. Saipan I., 
Tanapag Harbor, Kruckeberg, 3 vii 45 (mich). 
Chlorodesmis torresiensis Taylor 
Philippines. Luzon L: Cagayan Pr., Menabel, 
Edano 79001, 78993 A, iv 30. Filament diame- 
ters to 350p. Segments transverse-ended, with 
the constrictions equally placed. 
Avrainvillea Decaisne, 1842 
Avrainvillea erecta (Berk.) A. and E.S. Gepp 
Philippines. Palawan Pr., Balabac I., Abbott, 
2 iii 57 (bish). malaya. Singapore, Holttum, 
1928-30, Tanjong Ponggol, Holttum, 27 xi 27. 
Avrainvillea lacerata J. Ag. 
Philippines. Luzon I.: Pangasinan Pr., 
Alaminos, Fenix 13, 7 x 28. Indonesia. Java: 
Pangendaran, Setchell JP347, 349c, v 29. 
Avrainvillea obscura J. Ag. 
marianas islands. Saipan I., Tanapag Har- 
bor, Kruckeberg, 5 vii 45 (mich). The habit 
of these plants agrees excellently with this 
species, better than with A. erecta, but the sur- 
face filaments show a little brown discolora- 
tion. 
Cladocephalus Howe, 1905 
Cladocephalus sp. 
Philippines. Palawan Pr., Balabac I., Gnat 
Reef, Abbott, 4 iii 57 (bish). These specimens 
were in the form of a small tuft, with several 
short, stout, erect stems terminating in groups 
of rounded, slightly zonate blades 1-2 cm broad. 
The central blade filaments reached 15.5p diam. 
Those at the surface were 5.5-7.8p diam, less 
densely entangled than those of the West Indian 
C. luteofuscus (Crouan) Bprg. This is a most 
interesting thing to find in the area, but one 
hesitates to describe it as new on so little 
material, and material which is possibly 
dwarfed. 
Tydemania Weber-van Bosse, 1911 
Tydemania expeditionis Weber-van Bosse 
Philippines. Sulu Pr., Tawitawi I., Abbott, 
12 ii 57 (bish). Indonesia. Java: Thousand 
Islands, Kostermans 177, 5 x 38 (mich).
