THE RECENT CRINOIDS OF AUSTRALIA — CLARK. -fiTT 



Queensland on the east, and the coast north of Dirk Hartog 

 Island on the west. The southern coasts are tenanted by seven 

 species peculiar to Australia, but belonging to one endemic and 

 four tropical genera, which lend to that region an aspect very 

 characteristic, and yet at the same time without any especial 

 zoogeographic significance. 



The extent of the intrusion of the various tropical species into 

 Australian territory varies greatly, though possibly much of this 

 apparent variability is due to the present lack of accurate know- 

 ledge. 



On the eastern coast the following species are not known to 

 occur except at Cape York, or in the immediate vicinity of that 

 peninsula : — 



Comaster multijida 

 Comanthina belli
