PROSOBRANCHIATA. 193 



present species. Thus the Sub-apennine shells, described by Brocchi, and those from 

 Perpignan and Cassel, recorded by Sismonda, have been separated by Bronn under 

 the name C. Brocchii ; while to those from Dax and Gaas, described by Grateloup, 

 M. D'Orbigny has given the name C. Grateloupi ; and he has referred to the same 

 species certain shells described by Pusch, to which Eichwald had given the name 

 C. argillcecola. The cones described by Mr. Sowerby as belonging to the present 

 species are young shells of C. diadema. 



Dr. Beyrich (' Die Conchylien des Norddeutschen tertiiirgebirges,' vol. i, p. 24) 

 has described some shells from the North German tertiaries, which he has referred to 

 C. Allioni (Michel.), but which agree so well with the present species, that it is 

 difficult to separate them. That author states that, in C. deperditus of the Paris 

 basin, the shells are comparatively wider, the concentric lines on the margins of the 

 whorls more strongly marked, and the angles at the shoulders sharper than in 

 the German specimens. These differences do not appear to be greater than may be 

 fairly attributed to variations of local conditions, and I have therefore cited Dr. 

 Beyrich's shell, but with a query. The English shells are wider, and appear to have 

 attained a greater size, than the French shells ; and the edges of the shoulders, instead 

 of being somewhat sharp and elevated, as in the latter, are rounded or flattened 

 obliquely ; in all other respects our shells agree so well, that I have no doubt of their 

 specific identity.
