ON MOLLUSCA OF THE WEST COAST OF NORTH AMERICA. 583 
Thus a large body of species, named from types, was prepared for the New 
World ; but, unfortunately, through 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. Soc. 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 Molluscs, from 
1839-1862,’ Boston, 1862; with “Rectifications,” embodying such changes of 
nomenclature and synonyms as he desired to represent his matured views. 
In 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 
journals 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) 
(@) species certainly identical, (b) 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; while discus has never 
been found there, and is much flatter. ]
