• Experiments were conducted with nearly the same methods as those of Senô and his collaborators who worked on the eggs of Ostrea gigas, with the following results: - 1) The development of the eggs of Mactra sulcatria up to young shelled larvae was observed within a range of temperatures from 16° to 32°C, the optimum being 22°-28°C., and within that of salinities from 19.61‰ to 36.67‰ with the optimum 24.78‰-32.57‰. 2) The formation of larval shell is accelerated by higher temperatures up to 30°C., but it is retarded above this temperature. 3) The shell-formation is hastened by lower salinity down to 19.61‰, but it is slackened below this limit. 4) The percentage of abnormality of the fry varies inversely with the hatch-rate in relation to temperature.
