THE SEAWEEDS 
Z. crenata J. Agardh. Eastern Bays, Holdfast 
Bay, Port Noarlunga, Investigator Strait. 
Z. Diesingiana J. Agardh. Eastern Bays. 
Some authors (e.g., Setchell and Gardner 1925) 
include both Gymnosorus and Homoeostrichus under 
Zonaria, believing that J. Agardh ’s segregation is 
unwarranted, and although we recognize that the 
three genera are very closely related we have fol- 
lowed Agardh here. It is interesting to note the 
name Zonaria is really a misprint for Zornia in 
J. G. Agardh ’s 1872 monograph, but the name has 
been accepted by the International Committee and 
cannot be changed. 
Chlanidophora J. Agardh 1894. 
C. microphylla (Harv.) J. Agardh. Eastern Bays. 
In J. Agardh ’s 1894 monograph the name Chlani- 
dote appears in the key instead of Chlanidophora , 
and de Toni and some other authors have called the 
genus Chlanidote , but as Setchell and Gardner 
(1925) point out the correct generic title is 
Chlanidophora. 
Padina Adanson 1763. 
P. Pavonia Gaill. Would be expected to be found 
here, but has not as yet been definitely col- 
lected, 
Harvey includes P. Frazeri in his P. Pavonia.

gioni Tozzetti 1819.
