ON MOLLUSCA OF THE WEST COAST OP NORTH AMERICA. 583 



Iliiis a large body of species, named from types, was prepared for the New 

 World ; but, imfortunately, tkrougb imperfect packing and the practice of 

 marking by numbers only, much of the value of this identification was lost. 

 The new species were described by Dr. Gould in the ' Boston Proc. See. Nat. 

 Hist.,' 1859-1861 ; and on completion of the series, the author collected 

 the papers embodying the new species of the two great scientific expeditions, 

 as well as his other scattered publications, and issued them in a most valuable 

 book, entitled ' Otia Conchologica : Descriptions of Shells and MoUuscs, from 

 1S.'39-1862,' Boston, 1862 ; with "Eectifications," embodying such changes of 

 nomenclature and synonyms as he desired to represent his matured views, 

 lu quoting Dr. Gould's writings, therefore, this table should always be con- 

 sulted. A considerable portion of the specimens have been returned to the 

 Smiths. Inst., of which the larger species are mounted in the collection, and 

 the smaller ones have been sent to the writer to compare with those collected 

 by Mr. A. Adams, which were unfortunately being described in the London 

 joTimals almost simultaneously. The war has unhappily postponed the in- 

 tention of publishing the complete lists of species collected and identified with 

 so much accurate care. The following, however, have already been deter- 

 mined by Dr. Gould from the region in which American species occur. The 

 list is given entire (so far as identified), because species as yet known only 

 on one coast of the North Pacific may hereafter be found on the other. It 

 contains (as in the comparison of the Caribbean and West Mexican fauna) 

 (a) species certainly identical, (5) probably identical, (c) "interesting ana- 

 gues," and (d) representative forms.

The remaining species from these localities are either local or belong to the 

 Philippine and Polynesian fauna. At Simoda and Hakodadi we enter on a 

 mixed fauna.

locally abundant, however, on the West Coast ; wbile discus has never
