A histochemical and cytological study of the development of the shell in the gastropod, Helisoma duryi eudiscus.

The mechanism of the formation of the molluscan shell has been the subject of controversy since the first observations were made by Reaumer in 1709 on the normal growth and regeneration of shells. There is considerable agreement on the sites of secretion of the shell materiel and the histological id...
