The common Calif ornian Haliotis was, it seems, first described in the 

 Zoological Miscellany/ by Dr. W. E. Leach, vol. i. 1814*. 

 Page 131, pi. 58. Haliotis- Cracherodii, Leach. California. 



Solander made use of the materials he had collected in Cook's Voyage, in 

 compiling a work on Conchology of considerable merit. Dillwyn made a copy 

 of it, and used it in preparing his own, allowing priority to its specific names ; 

 but it was never published. The types were lately parted-with by the Lin- 

 nean Society, who had determined not to keep any collections except those of 

 Linnaeus. The ' Descriptive Catalogue of Recent Shells,' &c., by L. W. Dill- 

 wyn : London, 1817, is considered by Dr. Gray to be the best conchological 

 work arranged according to the old system. The following are quoted from 

 the West Coast : 



Vol. Page. 



i. 301. Mytilus frons, Linn. = Ostrea frons, Sol. Callone. Acapulco, Humphreys ; 



West Indies, auct. 



i. 469. Cyprcca pustulata, Sol. Acapulco. 

 ii. 617. Buccinum plumbeum, Chemn. California. [Monoceros, PS. America.] 



Following Dillwyn, and nearly eclipsing his fame through the originality 

 and excellence of his classification, appeared Lamarck's ' Animaux sans Ver- 

 tebres,' 1818-1822. Coordinate with or preceding this work are his Articles 

 in the ' Annales du Museum ' and the ' Encyclopedic/ The fresh sources of 

 his information are quoted in the first Report, p. 169. 



In Delessert's ' Recueil,' 1841, are figured 



PI. 2, fig. 1. Solen ambiguus, Lam. [ = rudis, C. B. Ad.] "Les mers d'Amerique."

In Deshayes' invaluable edition of the ' An. s. Vert.,' Paris, 1835-45, are 

 quoted a variety of West Coast species which have already appeared under 

 their original authorities. The following may be added : 



Vol. Page.

The last of the early writers whose works should here be quoted, and whose 

 ideas on the relations of genera were considerably in advance of the age, though 

 somewhat fanciful, is Swainson, in his 'Zoological Illustrations/ 1820-1833; 

 'Appendix to the Sale Catalogue of Mrs. Bligh's Shells/ 1822; and <Exoti<t 

 Conchology/ 1821-1835, reissued by Hanley, 1841. These works contain 

 the following West Coast species :
