84 MR. J. BRAZIER ON NEW-SOUTH-WALES CYPR^EID^E. [Jan. 16, 



1 7. Cyprcea helvola, Linn. 

 Hab. Bellinger-River beaches. 



18. Cyprcea poraria, Linn. 

 Hab. Bellinger and Redbank rivers. 



19. Cyprcea clandestina, Linn. 



Cyprcea moniliaris, Lamarck. 



Hab. Cape Banks, Botany Bay ; Watson's Bay, Port Jackson ; 

 Port Macquarie ; Macleay, Nambuccra, Bellinger, Redbank, and 

 Clarence rivers. 



I obtained living examples of this species at Botany during a very 

 low spring tide under stones, but have not seen it any further south. 



20. Cypr.«a xanthodon, Gray. 



Hab. Watson's Bay, Port Jackson {Mr. G. F. Angas) ; Broken 

 Bay ; Port Stephens ; Port Macquarie ; Macleay, Nambuccra, Bel- 

 linger, Redbank, Clarence, Richmond, and Tweed rivers. 



This species I have very rarely found in good condition. 



21. Cyprcea stjbviridis, Reeve. 



Hab. Port Stephens, Port Macquarie ; Bellinger, Redbank, and 

 Clarence rivers. 



Mr. Sowerby, in his ' Thesaurus Conchyliorum,' erroneously states 

 that this species inhabits the Cape-Verd Islands. New-Caledonian 

 specimens are more pyriform and lighter in colour than those fonnd 

 on the Australian coast. 



22. Cyprcea tlaveola, Linn. 



Hab. Botany- Bay Heads; Broken Bay ; Lake Macquarie ; Port 

 Stephens ; Port Macquarie ; also Macleay, Nambuccra, Bellinger, 

 Redbank, and Clarence rivers. 



This species is not very common at any of the above localities. 



23. Cyprcea spurca, Linn. 



Hab. Cape Solander, south head of Botany Bay (Mr. Hargraves) ; 

 Newcastle beach, near Redhead, north of Port Jackson. 



This species may be distinguished from C. Jlaveola and C. gan- 

 grenosa by the back being always clouded and ocellated with 

 yellow. 



24. Cyprcea lutea, Gronov. 



Cyprcea humphreysii, Gray. 



Cyprcea commixta, Wood. 



Hab. Lake Macquarie ; Newcastle beach ; Redbank and Clarence 

 rivers. 



The variety humphreysii has the back of the shell olive-brown, 

 with two narrow milky-blue zones, and comes from Nichol Bay, 

 North-west Australia.
