Abstract

The fully embryonated egg of Notocotylus attenuatus is shown to contain a sporocyst, an opercular cord and apparently 2 cells which are situated outside the sporocyst. One of these cells is rich in glycogen whereas the other contains a variety of inclusions. These contents are indicative of a truncated life-cycle which omits the miracidium, an observation as yet unique among the Digenea.
