The larvae of some monogenetic trematode parasites of Plymouth fishes

Abstract

Techniques for the rearing of monogenean larvae are described. The new term ‘oncomiracidium’ is proposed for the larvae of monogenetic trematodes. Eleven new oncomiracidia offish parasites are described, bringing the total now known to thirty-five. These oncomiracidia are tentatively classified, and the classification is compared with the existing classification of adult monogeneans.
