species, until he has obtained examples of them, when their validity 

 is readily acknowledged*. 



As regards species of which our excellent Foreign INIember has 

 authenticated specimens, every one would wish to hear his views, 

 and will respect them, although he may not agree with them. But 

 it would be certainly more prudent not to condemn in this wholesale 

 manner species with which he is not acquainted autoptically, and 

 described by naturalists in other countries who occasionally have the 

 advantage of examining specimens not yet possessed by the Leyden 

 Museum. 



4. A List of Species of Marine Mollusca found in Port Jack- 

 son Harbour, New South Wales, and on tlie adjacent 

 Coasts, with Notes on their Habits, &c. By Gteorge 

 French Angas, F.L.S., C.M.Z.S., &c.— Part I. 



[Tliose species marked with an asterisk ( * ) have been described from speci- 

 mens ill my own collection. — G. F. A.] 



Class CEPHALOPODA. 

 Fam. OcTOPODiDiB. 



Several species of Octopus, including one of very large size 

 (together with species of Cistojyus, Pinnoctopus, Eledone, 8lc.), are 

 occasionally to be met with in Port Jackson. Unfortunately but 

 little attention has hitherto been paid to animals of this class in 

 Australia. A careful examination and description of all the existing 

 species would, however, well repay the researches of a naturalist in 

 that part of the world . 



Fam. Argonautid^. 



1. Argonauta argo. 



Aryonauia argo, Linn. ; Reeve, Conch. Syst. v. 2, pi. 300. 



Very large shells of this species of Argonaut are occasionally washed 

 on shore upon the sandy beaches along the coast of New South 

 Wales. It seems to be identical with the A. argo of the Mediter- 

 ranean. Length 10 inches. 



2. Argonauta oryzata. 



Argonauta oryzata, Meusch. Mus. Gev. 252. n. 133. 

 A. tuberculata, Shaw, Nat. Misc. xxiii. t. 995. 

 Small examples of A. oryzata are now and then found about Port 

 Jackson, and on the beach at Coodgee and Botany Bay. It is in
