Communal spawning, egg capsule formation, oviposition, and the morphology of the egg capsule are described. Embryogenesis is outlined from the maturation divisions through the first torsional stage. Organogenesis which begins with consolidation of nervous and digestive anlagen is described in relation to the individual organ system. The organogenetic process is followed through the first planktotrophic veliger stage. Origin of natatorial independence, developmental variants in a related species, Purpura (=Thais) lapillus, and the taxonomic characters of the first planktotrophic veliger stage are outlined.
