The Australian Crinoid Fauna. 



All the crinoids knowu from the Australian coasts belong to unstalked 

 groups, no stalked forms yet having been discovered there. 



Of these uustalked forms, or comatulids, Australia possesses forty-six 

 species, distributed among twenty-two genera and subgeuera, eleven families 

 and subfamilies, and two suborders, as follows: 



I. OliyopJireata. 



Comtisteridae. 



1. Capillasterinae '2 genera and 3 species 



2. Comactiniinae 2 1 ) ,, ,, 6 ,, 



3. Comasterinae 4 ,, ,,9 ,, 



4. Zygometridae 1 genus ,, 3 ,, 



5. Himeromelridae 3 genera ,. 7 ,, 



6. Stephanometridae 1 genus ,, 1 



7. Mariametridae 1 ,,4 ,, 



8. Colobometridae 4 genera ,, 6 ,, 



9. Tropiometridae 1 genus ,, 2 ,, 



10. Thalassometridae 2 1 ) genera ,, 3 



II. Macrophreata. 



Antedonidae. 



11. Antedoninae 1 genus ,, 2 



All of the families and subfamilies are characteristically East Indian, 

 and all but the Tropiometridae and the Comasterinae possess additional 

 genera in that region. 



The genera are all characteristically East Indian except two, both of 

 which, peculiar to Australia, are confined to the southern portion of the 



1) One of these genera is confined to southern Australia.
