A, B, C: Fasciola hepatica eggs.  Wet mounts with iodine.  The eggs are ellipsoidal.  They have a small, barely distinct operculum (upper end of the eggs in A and B).  The operculum can be opened (egg in C), for example when a slight pressure is applied to the coverslip.  The eggs have a thin shell which is slightly thicker at the abopercular end.  They are passed unembryonated.  Size range: 120 to 150 µm by 63 to 90 µm.
