Description	Ultrastructural aspects of the early embryonic development of the aspidogastrean Aspidogaster limacoides are described and their phylogenetic implications discussed. Whereas the proximal regions of the uterine lumen usually contain unembryonated eggs or eggs with early embryos, the posterior or distal regions of the uterus are filled with eggs containing a fully-developed cotylocidium. The eggs of A. limacoides can be classified as polylecithal due to the presence of numerous vitellocytes which accompany each fertilized oocyte or ovum during egg formation. The results of the study are described in details under six headings: (1) general characteristics of the intrauterine eggs; (2) eggshell and operculum formation; (3) unembryonated eggs; (4) zygote formation and early cleavage divisions; (5) embryonic envelope formation; and (6) early degeneration or apoptosis of some blastomeres.
