Of the Order SCYPHOMEDUS only 26 Australian 
species are known, but additional species may be expected 
from better acquaintance with the productions of the seas on 
the north coast. The very curious genus Pseudorhiza is 
peculiar to Australia. The Ruizostomz constitute the chief 
Australian group. The CrEnopHora are present in Australia, 
but in very small numbers, as far as at present known. The 
Orders HURYSTOMATA, SACCATA, and THINIATA 
are each represented by one or two species. A very beautiful 
Beroid has been described from Port Jackson. 
The last Sub-kingdom of the Animalia, the PROTOZOA, 
may be passed over: they are much the same everywhere. 
The Australian representatives of the various classes comprising 
the Sub-kingdom have never been investigated.
