The identification of these species is attended with great uncertainty, as
the types have not been seen, and the artist appears to have studied effect
rather than accuracy.

42. Voyage of Sulphur. The types of these species appear to have been
scattered. Only a part are now to be found in the very valuable collection
of Admiral Sir E. Belcher, in which most of the shells are, unfortunately,
destitute both of names and of locality-marks.

Murex Belcheri [belongs to Purpuridse, and may be considered the type of
the genus Chorus].

Ranella California. [After comparing a series with the Cumingian speci-
mens of R. ventricosa, it appears that the diagnostic characters are not con-

Marginella sapotilla. [The type in Mus. Cuming is much smaller than
the ordinary condition of M. prunum=ccerulescens, Lam., to which species
the common Panama shells were referred by Mr. Cuming. In his collection,
however, they stand thus : Ordinary Panamic type " sapotilla, Hds. : 5-13
fms., sandy mud, Panama, H.C" Another tablet of the true Panama shells
" Marginella, n. sp., Panama," " San Domingo" having been crossed ouf.
The small West Indian form, analogous to the typical sapotilla, is given as
" glans, Mke." The large West Indian shells, with violet tinge behind the
labrum, are " ccerulescens, Lam., Panama," without authority. Another series
of the W. Indian type is given as " ccerulescens, var., Lam., 10 fms., sandy
mud, Panama," without authority. Either habitat- errors have crept into the
Cumingian labels, or else Mr. Redpath's observation will not hold, viz. that
the Atlantic shells have a posteri< r pinch on the labrum, which is not seen
in the Pacific. All the authentic series examined irom the two coasts bear
out his view. There will be two opinions as to whether this be more than
a mere local distinction.]

Solarium quadriceps. [On comparing suites of S. granulosum from the
Texan coast with series from the Gulf of California, it appeared that on each
side of the Peninsula the shells went through similar changes in strength of
sculpture, size of umbilicus, number of spiral granules, &e. ; nor could any
clue be obtained by which the coasts could be separated in a mixed collection.
Hinds's shell stands at the furthest extreme of -removal from S. granulatum.~\

43. U. S. Exploring Expedition. The shells of this collection were depo-
fiited in the Patent Office in Washington, D.C., where, notwithstanding the
great care of Mr. Varden, the curator, they were not a little tampered- with.
Dr. Gould laboured under great difficulties in his work of description ; he
had access only to that part of the collection which happened to be unpacked
and exposed to view during the brief period that his professional engagements
allowed of his visiting the capital ; and his request to be allowed to take
doubtful shells to Europe for identification was refused. The materials also
were of an unsatisfactory kind, a large proportion of the specimens being
much weathered, and many of the locality-marks being manifestly erroneous.
,lf occasional errors have been detected in his great work, they may fairly be
let down to causes over which the author had no control. Many of these

have been corrected by Dr. Gould himself, in his ' Otia Conch ologica/
Boston, 1862, which contains the various papers in the 'Proceedings of the
Boston Soc. of Nat. Hist.,' with an appendix. After the organization of the
Smithsonian Institution, all the natural-history collections belonging to the
Federal Government were transferred to its keeping, with liberty to exchange
duplicates. The shells remained unopened, and the types not accessible, till,
at the request of Professor Henry, I undertook the arrangement of the col-
lections. Fortunately, a considerable part of the shells professing to be
the figured types of the new species were found together, with the artist's
marks corresponding with the plates and figures. The result of the exami-
nation, so far as the general collection is concerned, will shortly be prepared
for the press ; it is sufficient here to tabulate the observations on the N.W.
American species, which were, as it happened, the most satisfactorily pre-
served in the whole series. The following additional particulars include the
" Rectifications " in the ' Otia,' the paging of which is continued from the
" Expedition Shells " quoted in Rep. p. 209. The quarto volume quoted in
p. 210 is distinguished as " E. E. Mollusca." The folio atlas of plates bears
date on title 1856, but was not published till 1861, teste Binn. Bibl. vol. i.
p. 504. The comparisons of types were made in 1860, from a proof copy.

and all the others seen from the coast, agree in belonging to Ischnochiton,

trum, Nutt, while 4566 represents the flattened variety of A. persona,
Esch. (approaching the form digitalis, Esch.). As the diagnosis best
accords with the latter shell, P. scabra, Gld., may stand as a synonym of
persona, var. ; the intermixed specimen, accidentally figured as belonging
to the species, being removed to spectrum, Nutt. Thus the name scabra,
not being needed as first described, will remain for Nuttall's species,
described by Rve., but first named in print by Jay.]

rough northern form of Tapes staminea, Conr., which is the Saxidomus
Petitii of Desh., and includes V. ruderata, Desh. But the "specimen,

figured at f. 538, proves to be the adult form of Tapes tenerrima, Cpr.,

44. Middendorff. The synonymy given in Hep. pp. 214-222 is that of
the author, not of the writer of the Report, who is by no means prepared to
accept the learned doctor's identification of species. The three Chitons quoted
with doubt from Tilesius have not been confirmed, as from Kamtschatka, by
any other writer. The Ch. giganteus has the aspect of the large Ischnoclriton
Magdalensis ; the Oh. muricatus belongs to the LopTiyrus group, which is not
known so far north ; and the Ch. setosus has also a S. American aspect. The
treatise " De Chitone Giganteo Camtschatico additamentum ad Zoographium
llosso-Asiaticum, auctore Tilesio," was read March 19, 1823, and publi.-Ouvl
in 1824. It contains a very valuable and (for that period) remarkable account
of the anatomy of Chitons, but it does not profess to name and describe species
in the modern sense. The names, therefore, had better be dropped. Midden-
dorfFs new species were first described in the ' Bulletin de la Classe Physico-
3Iathematique de 1'Acade'mie Imperiale des Sciences de St. Petersbonrg,' a
work of which few complete copies are known in England, under the follow-
ing dates.
