NOTICE.

In presenting this series of illustrated monographs to the public,
the editor wishes to express his thanks to those friends who have
assisted him by permitting the use of their specimens, and by drawing
up those monographs which appear under their names. He is also
grateful for the general support with which he has been honoured
during the progress of the work. The difficulties experienced in col-
lecting the necessary information, the great labour and expense of the
illustrations, and the comparatively slow return of the capital employed,
are the reasons for those long intervals between the appearance of the
Parts, which have been so much complained of.

As the latter difficulty gradually gives way, the former will be over-
come, as the editor will be enabled to give more time to the work, and
to obtain increased assistance in the subordinate departments.

The editor having heard of those who would wish to possess the work,
but are deterred from doing so on account of its slow appearance, begs
to suggest that their subscriptions would contribute towards the re-
moval of the evil which they deprecate. If a small number of additional
subscribers were obtained; if a few of the more affluent subscribers
would take a second copy; and others, by shewing the present volume
to their friends, were to induce them to join in patronizing the under-
taking, there would be no difficulty in producing the parts at short and
regular intervals. Those who are anxious for such a result may pro-
mote it in this way.

As one effect of that increased support which has already commenced,
it will be seen that in the latter Parts a larger number of plates has
been given, and the letter-press has been fuller in proportion, than in
the earlier Parts. It is intended to carry on the work in future on
the same scale of increased liberality ; and- the editor cherishes a hope
that the successful termination of the present volume will so far add to
the list of subscribers as to enable him to proceed with greater rapidity
with the successive monographs.

The ‘ Thesaurus Conchyliorum’ will in future be published at No. 70,
Great Russell Street, Bloomsbury, to which place Mr. G. B. Sowerby,
Sen., F.L.S., is removing his stock of Books, Minerals, Fossils, and
Shells. Among the latter will be found many of the species described
and figured only in the monographs, as well as others more generally
known, G.B. Sowerby, Jun., having made arrangements to assist in
the business, will be happy to supply the desiderata of those who may
favour him and his father with their commands.

N.B. The binder will observe that Pages 83 to 186 have been, by
error, repeated; but the table of contents will prevent confusion.

*,* Tn binding his own copy, the editor intends placing the plates
in one cover, and the letter-press in another, and thinks the subscribers
will find it most convenient to do the same.
