222 Proceedings of the Royal fiovictij of Victoria. 



Obs. — We previously followed several authors in setting this 

 do^\^l as Choristodon lapicidum, Chemnitz, but not having 

 access to Chemnitz's work we were unable to see his treatment. 

 As, according: to Dr. W. H. Dall (Proceedings of the National 

 Museum of the United States, vol. xxvi., p. .339), a gi-eat deal 

 of Chemnitz's work is not binomial, we should apparently accept 

 Lamarck's naming. The type of C. lucinalis, Lamarck, origin- 

 ally came from King Geoi'ge's Sound, New Holland. 



•Chione striatissima, Sowerby. 



See part vii., pp. 125, 126, to replace Chione cardioides, 

 Lamarck. 

 Obs. — In our last paper we stated that it was Venus car- 

 dioides, Lamarck, from the West Indies which would require a 

 change of name if it proved to be a Chione. Mr. Hedley has 

 drawn our attention to the fact that Deshayes, in his British 

 Museum Catalogue of the Veneridae, did class this species as 

 a Chione, and on referring to the work we find that Deshayes 

 lias also correctly included Cytherea cardilla, Lamarck, as a 

 •synonym. In dealing ^vith Chione striatissima. Sow., however, 

 Ave overlooked the fact that Sowerby gave this name for Erycina 

 cardioides, Lamarck, owing to his rather obscure method of 

 doing it without any comment or explanation. 



Circe pythinoides, T. W^oods. 



See part vii., pp. 131, 132. 

 Obs. — This shell, as already indicated in the previous part of 

 this catalogue, is in the National Museum Collection, Mel- 

 bourne, and is labelled as from Port Phillip Heads. We have 

 not hitherto seen any other specimens in any Victorian collec- 

 tion, and a re-examination of the type specimens of the above 

 has convinqed us that it is synonymous with Circe gibbia, 

 Lamarck (Cytherea), from Queensland and the Pacific. We 

 therefore think that it is highly probable that some mistake 

 may have been originally made in attributing this species to 

 Victorian waters. The ty]De is only a partially grown, shell, 

 and therefore not so tumid or elongate as the full grown C. 

 gibbia, but agi-ees well in all other respects.
