VI. On the development of Lichenopora verrucaria , Fabr

The principal results of my examination of the life-history of Lichenopora have already been communicated to the Royal Society. I then showed that embryonic fission occurs as a normal process in the development of that genus, as of Crisia. The general growth of the colony and of the embryo was described, and attention was called to the remarkable fact that the embryonic processes which culminate in the production of the entire first brood of larvæ commence in the earliest stage of the formation of the colony itself.
