Abstract: Heretofore, observations on the spawning and development of the internally fertiltizing intertidal snails, L. planaxis and L. scutulata have been limited to studies conducted by Hewatt(1938) and by Glynn (1963). Recent observations at Hopkins Marine Station on the central California ceast further elucidate the reproductive biology of these littorines. These studies, conducted in the laboratory and in the field in the period April 21 to May 29, 1964, shed some light on spawning behavior and suggest relationships between development and ecological conditions pertaining to these two species.
