Marine Biology, 1972 Cultures of developing larvae of Gibbula cineraria (L.) were obtained from adults spawning in the laboratory, and these cultures were reared to settlement of the larvae at 9 days. Dispersal of the outer jelly coat of the egg appeared to be delayed in the presence of spermatozoa.

Muscle morphogenesis in primitive gastropods and its relation to torsion
Proceedings of the Zoological Society of London, 1955 SSummaryInHaliotis tuberculata, Patella vulgata and Patina pellucidathe young are hatched at an early trochophore stage and remain only a few days in the plankton, but inCalliostoma zizyphinumthe whole of this phase takes place within the egg membranes and the larva is plantigrade from the time of hatching.In all four genera the larval retractor muscle

Evolution & Development, 2002 SUMMARY Results of this study on two species of vetigastropods contradict the long‐standing hypothesis, originally proposed by Garstang (1929), that the larval retractor muscles power the morphogenetic movement of ontogenetic torsion in all basal gastropods.
