The common Calif ornian Haliotis was, it seems, first described in the
Zoological Miscellany/ by Dr. W. E. Leach, vol. i. 1814*.

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 :
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 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 :

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 :

The types of the species described from this important voyage have been
scattered. Some have been identified from Admiral Sir E. Belcher's Collec-
tion, which he kindly allowed me to examine for that purpose ; others are
in the possession of Mr. Hanley ; but many appear hopelessly lost.
29. Wood's Ind. Test. In Hanley's Revised Edition of this important
work (London, 1856), several new localities are added from the writer's
varied experience, and the synonymy is most carefully elaborated. No other
book contains such a mass of trustworthy information on the old species in so
small a compass. The following are quoted, either as original authorities, or
for locality or synonymy :

schisma. The Indians have a superstitious dread of handling it. Many more
species have since been detected in the Brit. Mus., from the late Lady
Wigram's valuable donations, including Macoma inquinata, Desh.. described
from her specimens ; but, as they are evidently from mixed localities, it has
not been thought necessary to catalogue them.]
39. Nuttall. The verification of Conrad's species being of considerable
importance, I made diligent search for the original types during a recent
tour in the United States. The supposed collection at Harvard University,
Cambridge, Mass., has not been discovered by Professor Agassiz. The
inquiries which Professor Longfellow kindly made at my request resulted in
information that it was " in Dr. Wyman's Mus. Nat. Hist., in the granite
building on Howard Street ; " but no opportunity has been afforded of col-
lating it, or even of verifying its existence. Dr. Jay rendered me every
assistance in studying the types which he has catalogued in his collection,
now rearranging in his residence at Memironeck, near New York, and gave
such duplicates as could be spared for the Smithsonian Museum. Several
species, however, were not to be found, and some were clearly erroneous, as
e. g. Chama " exogyra, Conr.," which proved to be C. lobata, Brod. ; "W. L,
teste Cuming ; China, Brit. Mus. The most satisfactory information was
derived from an interview with Mr. Conrad himself at the Acad. Nat. Sci.,
Philadelphia, where the honorary curator, Mr. "W. G. Binney, afforded us
nil possible aid in eliminating types from the collections of the Academy and
of private conchologists in the city. Mr. NuttalPs death (the news of which
was received soon after) prevented his revising the corrections thus obtained.
As he had previously presented a duplicate series of his shells to the Brit.
Mus., which had been incorporated with the general collection, and had sig-
nified to me his intention to leave the unique specimens to the nation, I at
once communicated with the survivors and with Dr. Gray, who was fortunate
enough to stop the intended sale, and to secure the shells, which were kindly
presented by the executors. They are now mounted, and kept in drawers
adjoining the Reigen collection, the Vancouver collection, and the Stimp
sonian typical collection of East Coast N. American shells. The following
is a resume of corrections obtained from these different sources, numbered to
correspond with the list, Rep. pp. 194-201 :

Gray. Mr. Nuttall only brought home young specimens of this extraordinary
shell. In its adult state it assumes either a transverse form ( = capax) or
the elongated condition, redescribed in a fossil state as new. Between
these there is every gradation, as can be traced in the magnificent series in
the Smiths. Mus. ; and a caskful of the animals in spirits, of various ages,
has affiliated the large shells to the original Nuttallian specimens.]
