Abstract
Cercaria laevicardii sp. nov. is described from the marine lamellibranch, Laevicardium mortoni. The cercaria develops in simple sporocysts and is similar to the larva of Bacciger bacciger. The excretory formula is 2 [(3 + 3) + (3 + 3)] and the structure and development of the excretory system is such that the larva is interpreted as having been derived from the furcocercous type. Various caudal modifications in fellodistomatid cercariae are discussed and the possible phylogenetic significance of some types is mentioned.This publication has 0 references indexed in Scilit:
