996 ON A COLLECTION FROM NORFOLK ISLAND — MOLLUSCA. 



Purpura neglecta are quite smooth, and have not the characters of 

 Sinusigera. Tlie splendid figure given by De Blainville in the 

 " Nouvelles Annales du Museum," pi. 8, fig. 18, of his Purpura 

 Tritoni/ormis, need never be mistaken for any other species ; 

 Dunker's specific name of typica must stand as a synonym. 



12. Nassa (Alectrion) spirata, A. Ad. 



Naxsa spirata, A. Adams, Proc. Zool. Soc. London, p. 106, 

 1851 ; Nassa spirata, Reeve, Conch. Icon. pi. 2, fig. 13. 



The specimens are in very good condition considering that they 

 were found on the beach ; the species is also found at Lord Howe 

 Island, and on the coast of New South Wales, at Broken Bay 

 and other places to the north. 



13. Nassa (Hima) paupera, Gould. 



Nassa paupera, Gould, Moll. Wilkes' Expedition, fig. 330 ; 

 Nassa (Hima) rufocincta, Angas {non A. Adams). 



The specimens are variable in colour, some being white, 

 yellowish-brown, reddish-brown, or spirally banded with brown 

 broken lines ; they are much stouter than those from Port Jackson 

 and the coast of New South Wales. 



Mr. Angas in his list of Port Jackson Mollusca, quotes this 

 shell as Nassa rufocincta, A. iVdams ; the Nassa rufocincta of A. 

 Adams is a synonym of Nassa versicolor, C. B. Adams, a 

 shell from Panama.
