Extract

1. A new genus of trematode (family Allocre-adiidae) from the intestine of freshwater eels is described, and named Stegodexamene anguillae.

2. The genus is related to Aephnidiogenes, Lepidapedon and Neophasis, but differs significantly from each of them.

3. The life cycle followed is from the adult in Anguilla dieffenbachii to the redia in Potamopyrgus antipodum (fresh-water gastropod). The cercaria encysts in the eloetrid fish Gobiomorphus gobioides.

4. Progenetic production of eggs and spermatozoa occurs in the metacercariae.

5. Metacercarial excretory spherules are composed of calcium carbonate.
