Taxonomy 
A taxonomic revision of Cassiopea is needed as there are 
a number of difficulties in recognizing species within the 
genus with currently used character suites (Holland, 2004; 
Gershwin etal ., 2010; Shapiro, 2014). On the basis, however, 
of characters highlighted by Mayer (1910) and Gershwin et 
al. (2010) in comparison with paratypes of C. maremetens 
in the Queensland Museum (QM G.6645, Fig. 2I-L) and 
other specimens in the collections of the Australian Museum 
(AM), it is apparent that two forms are present in the samples 
from New South Wales, identified here as C. ndrosia (Lake 
Illawarra) and C. cf. maremetens (Wallis Lake).
