ON MOLLUSCA OF THE WEST COAST OF NORTH AMERICA. 169 



province is due to the French botanist, Joseph Dombey. He arrived in 

 Peru in 1778, and brought home several shells, of which eight species are 

 described by Lamarck*. {C. B. Adams. ^ 



24. The earliest authentic collections, however, made on the Pacific shores 

 of N. America were obtained by the celebrated Baron Humboldt and his 

 companion M. Bonpland. In 1803 they reached Peru, whence they sailed 

 to Acapulco. It is to be regretted that they did not themselves describe the 

 shells they brought. They were seen, indeed, by Lamarck, who described 

 eleven species from them; but the detailed account was entrusted to M. Va- 

 lenciennes, and was not published till 1833, the descriptions having been 

 written in Nov. 183 If. In vol. ii. of " Recueil d'Observations de Zoologie et 

 d'Anatomie Comparee, faites dans I'Ocean Atlantique, dans ITnterieur du 

 Nouveau Continent, et dans la Mer du Sud pendant les annees 1799-1803, 



* An important aid in the understanding of the Lamarckian species was given by M. De- 

 lessert, who published a magnificent volume of plates entitled " Recueil de Coquilles decrites 

 par Lamarck dans son Hist. Nat. des An. s. Vert, et non encore figurees. Paris, 1841." A 

 copy may be seen in the library of the Linn. Soc, and a list of species is given by Menke in 

 his ' Zeit. f. Mai.' June 1844, pp. 83-95. 



t The following Table may aid the student in deciding questions of priority : the lists 

 being given in the approximate order of collection ; the order of publication being very 

 different.
