Summary Some details concerning the reproduction of 2 Indian species of the supralitoral prosobranch genus Assiminea are described and compared with those of a North Sea species. The eggs are deposited on the mud surface and covered by an oblong cap formed of faecal pellets. The transversal dimension of the cap is correlated with the species-specific size of the pellets, the length corresponds to the number of eggs covered. In the North Sea Assiminea the cap is more or less straight, in the Indian species it meanders or is coiled up. The free-living veliger stage in both tropical species is more extended than in the North Sea species; this observation agrees with the rule of Thorson.
