54 NOTES. 



LTNTHIA AUSTRALIS. 



I doubt if this species has ever been obtained in Port Jackson, 

 most of the specimens so labelled in the old collection prove to 

 be Brissus carinatus. The only specimen we have at present 

 a denuded test was probably found on one of the adjacent 

 sea-coast beaches. It is stated to be not rare on the coasts of 

 South Australia, but as yet I have seen no specimens from that 

 Colony. 



SCHIZASTER VENTRJCOSUS. 



We have occasionally dredged this species near the Heads of 

 Port Jackson in 6 to 8 fathoms, but at all times it is rare.
