Choristodon rubiginosum, Adarus and Angas. 



dementia Tasmanica, Petterd !, is a synonym. 



Venurupis carditoides and V. crenata, Lamarck, are rightly 

 identified according to the British Museum naming. 



Tapes fabagella, Deshayes, of my collection agrees with the 

 type in the British Museum. 



Chione gallinula, Lamarck, as so named from South Aus- 

 tralian waters, agrees with the type. Venus australis, Sow., 

 is perhaps not the same species, the type specimens have finer 

 and closer concentric ribs than the type of V. gallinula, whilst in 

 outline it is more triangular, the post-ventral margin rising more 

 quickly. 



The locality of Lamarck's type is King Island, that of 

 Sowerby's King George Sound. 



C. australis has not been found in South Australian waters. 



Chione Peroni, Lamarck !, with which C. aphrodinoides I 

 should be united. C. conularis ! may be the young state. This 

 species in my Revision, IX., p. 92, is quoted as C. scalarina. 

 Reeve, in Mon. Venus, gives an excellent figure of it (t. 17, f. 73) 

 under the name of C. aphrodinoides. 



Chione strigosa, Lamarck !. C. aphrodina, Lk., is obviously 

 from descriptions and figures a synonym. In my Revision the 

 species is quoted as C. aphrodina. 



Chione sp. unnamed. The shell incorrectly referred in my 

 Revision, IX., p. 92, No. 67, to C. strigosa, I failed to identify in 

 either the Paris or British Museum. It may possibly be C. 

 scalarina, Lamk., which I have not seen, or any examples 

 attributed to it. It agrees very fairly well in outline with 

 Reeve's figure of it, which represents a shell of medium size, par- 

 ticularly in the somewhat arched post-hinge line, but no descrip- 

 tion of C. scalarina alludes to the very distinctive ornamentation 

 of our shell. 



Dosinia Diana, Adams and Angas, id Tate, op. cit., IX., p. 93. 



The type of this species and the shell I figured as D. grata are 

 certainly the same, but they are different from D. grata. 

 D. diana appears as if it were a worn D. crocea without the 

 coloration on the escutcheon. D. crocea is slightly coarser ribbed, 

 and more depressed than D. diana. 



Dosinia crocea, Deshayes. This is a wrong identification, but 

 it agrees with D. histrio, var. from Swan River, in the British 

 Museum. It has the concentric ribs coarser and wider apart 

 than in D. grata. 



Meretrix alatus, Reeve. This is in substitution for Cytherea 

 lutila, Sow., and in harmony with the British Museum record. 

 M. rutilus is a different species. 



Meretrix mxdtistriatus, as quoted from Tasmania, can only be
