| Abstract: | The paper is one of the series researches on biology of Cultellum scalprum (Gould). It reports on pre- liminary research into the gonad development and the histology of Cultellum scalprum (monthly sample 80- 100 ind., total 1270 ind.) from February, 1985 to February, 1986 In Funing Bay, Fujian, China. The gonad development is divided into 4 stages: increase stage (from February to April and July to August); maturation Stage (at the last port of April till May and at the last pert of August till September); ovulation stage (at the last part of May till June and at the An Part of September till October); exhaustion stage (at November till January next year).
