NEW PROPOSED WORK, BY G. B. SOWERBY, F.L.S.

GENERIC FORMS OF SHELLS ILLUSTRATED.

The Author has long been engaged collecting materials for this Work, which is to contain a harmonization of existing systems, in which a balance will be struck between a too negligent and too minute subdivision. Comparative susceptibility of _definition_ will be the guiding principle in deciding the claims of certain groups to generic separation. The illustrations will be copious and of full size, embracing every marked form, whether recent or fossil, and whether adopted as a genus or not. The price is not yet fixed, but is expected to be about £3 3s. To appear between March and May, 1866.

G. B. S., jun., will be glad to receive the names and addresses of those who desire to see the Work when published.
