1 Dana remarks that perhaps this is only the E. cordata, Morris {Am. Jour. Sc. ISIS, v. p. 434>>. 



2 The genus Inoceramus was proposed and described in a paper read before the Linnean Society 

 on Nov. 1st, 1814, by Mr J. Sowerby, "On a fossil shell of a fibrous structure, &c." The dtscription 

 appeared in pt. 2, vol. xiii. Linn. Trans., which Mr 11. Ki])pist, Librarian to the Society, informs me 

 was published in Dec. 1823. In the mean time Parkinson published a description of the genus {Trans. 

 Gc'ol. Soc. V. p. 55), the latter work beariiiK date 1819. This must therefore be accepted as the 

 nal date of the publication of Inoceramus, and not ISli, as is usually given in catalogues and works.
