1000 ON A COLLECTION FROM NORFOLK ISLANjj MOLLUSCA. 



A number of living specimens in the collection. I collected a 

 lai-ge number when last at Norfolk Island in 1865. 



It is very common on some parts of the coast of New South 

 Wales, at Bondi and Coogee Bays, and on the outer north head 

 of Port Jackson, Point Piper, Watson's Bay, and Lord Howe 

 Island. 



Lamarck's name of Brasilianum for this species is a misnomer, 

 the shell not having been found in Brazil. I believe the original 

 specimens that came into Lamarck's hands from Madame Paterson 

 came from either Lord Howe Island, Norfolk Island, or New 

 South Wales.

 ■atrata, Angas, Proc. Zool. Soc. Loudon, p. 175, No. 123, 1865. 



One single sea-worn specimen is in the collection. I found 



it very common under stones during 1855-1856, and again in 



-company with Mr. Brenchley in H.M.S. Cura9oa in 1865, 



Found by MacGillivray on Raoul or Sunday Island, Kermadec 



Islands (Voyage of H.M.S. Herald). 



The Rev. Boog Watson is evidently wrong when he asserts in 

 Vol. XV., Zoology of H.M.S. Challenger, p. 133, that Quoy and 

 Caimard state Nerita jiunctata came from New Holland. Quoy 

 and Gaimard state nothing of the sort; they distinctly say that their 

 specimens came from the Isle of France (Mauritius), and I main- 

 tain that their Nerita punctata is distinct in every respect from 

 Nerita melanotragus, of E. A. Smith, our Port Jackson shell. 

 The Nerita punctata of Quoy and Gaimard, I have from
