On studying this list of Australian Tertiary species of Echinoidea ? 

 it will be observed that there is but one species (Schizaster ventri- 

 cosus) which belongs to the recent fauna. It has not an Australian 

 habitat, but is found widely in the Pacific area and as far north as 

 Japan. Of the nineteen genera found represented in the Tertiaries, 

 only seven, possibly, have species in the recent Australian fauna,
