them may range as far south as Wide Bay, Queensland, and 
some are known to reach Port Jackson, New South Wales. 
2. South Australian subregion, including Tasmania and the 
mainland coast south of 35°S. Lat. It merges on the 
east coast with the East Australian subregion, and 
some of its characteristic species reach Port Jackson. 
This is the typical Australian marine fauna and 
includes about one hundred and twenty species or 
approximately 30% of the known Echinoderms. 
More remarkable, however, is the fact that the great 
bulk of this fauna is endemic or at least is not at 
present known from elsewhere. Apparently not more 
than a dozen of the Echinoderms known from the 
southern coasts of Australia range north of Lat. 28° 
or east or west of the Australian region. A very few 
(of which Ophionereis schayeri is a conspicuous example) 
occur in New Zealand. One (Hchinus horridus) is 
known from South America and South Africa and 
perhaps more will ultimately be found with that range. 
One starfish (Luidia maculata) has the very unusual 
range of encircling the Australian continent and 
reaching China and Southern Japan on the north. 
The following are some of the most characteristic 
species of this remarkable fauna :— 
CRINOIDS. 
Comanthus trichoptera. 
Ptilometra macronema. 
Compsometra incommoda. 
ASTEROIDS. 
Nectria ocellata.
