Abstract

Crewe1 has recently discussed the possible influence of helminth parasites on sex determination in limpets. Following the earlier observations of Orton2, I have been studying the problem of sexuality in the Mediterranean limpet Patella coerulea L., both statistically and histologically. In contrast to the conditions in Patella vulgata, no larval Trematodes have been observed in several thousands of P. coerulea which I have examined. These parasites-must therefore be at most extremely rare in the present populations of Patella in the Bay of Naples.
