258 THE PROCEEDINGS OF THE LTNNEAN SOCIETY 



Very closely resembles the figure of N. Grayii, Deshayes, of 

 the Icon. Conch., which, however, is believed to represent a larger 

 and more ventricose shell than that of Kiener. 



[This may be N. rufocincta, A. Adams, which, however, he 

 states came from the Honduras, Port Jackson, and on all the 

 N. S. W. coasts. J. E. T. W ] 



(Loc. cit. p. 337.) — Clathurella peregrina. 



T. avato-fusiformis solida, obscure fulva, plicis obtusis ad 18, 

 filis transversis (ubi plicis decussantibus) ornata ; anfr. 6, ventricosis. 

 Aperture |- totius longitudinis lineata, postice rotundata, labro acuto, 

 intus lamellato, canali brevi, angusto, abrupte incepto. Ax 12, 

 diam. 5 millim. Hab. Sydney Harbour. 



Closely allied to C. assimilis, but less colored, and the strise 

 less crowded. 



[This shell is very common in Port Stephens, and appears to 

 have been re-named lately in the Zool. Proc.) 



(Loc. cit. p. 3S6.) — Cerithium lacertinum. 



T. turrita fusiformis, tenuis, cinerea, fusco maculata; anfr. 10, 

 convexiusculis, bene discretis, posticis plicatis, et fills granulosis 4, 

 ad anfr. ult. demum simplicibus cinctis, minoribus plerumque inter- 

 venientibus. Apertura semilunaris, labro acuto, rostro abbreviato. 

 Ax. 13, diam. 4 mill. Hab. Sydney Harbour. 



Exceedingly like C. lima Brug. It has no varices, is less 

 slender and differently colored. It is also like C. granarium 

 Kiener. 



[This is evidently C. lawleyanum of Crosse, which must give 

 way to Gould's name. J. E. T. W.] 



(Loc. cit. p. 409.) — Rissoina flexuosa. 



T. fusiformi, turrita, straminea, anf. 7, convexiusculis, plicis 

 obtusis, fiexuosis circiter 15, clathratis et lineis volventibus nume- 

 rosis cinctis, apertura satis magna, semicircular is, peritremate sim- 

 plici expanso, antice effuso. Axis 6, diam. 2. Sydney Harbour. 



[This shell is not known to me, but may have been redescribed 

 amongst our numerous species of the genus. J. E. T. W.]
