C); a large bulbous, asymmetrical mass of fused elongate cells (resembling a large gland at the ectal duct orifice when observed in vivo) surrounding a narrow canal that opens to the orifice through a straight or curved slit at 4/5, and a thick-walled section (ca. 20–25 µm in width) entally gradually widened into the ampulla. Ampulla simple, elongate, slightly wider than ectal duct, and not attached to oesophagus. Sperm present in all parts of the ampulla, usually concentrated in the terminal part.
