Extract

1. Coitocaecum anaspidis sp.nov. is a Trematode which exhibits precocious genital activity whilst encysted as a metacercaria in the Tasmanian Mountain Shrimp, Anaspides tasmaniae Thomson.

2. Eggs are laid by the Trematode whilst in the encysted condition, and in some cases the eggs hatch in the cyst giving rise to miracidia which swim freely in the contained fluids.

3. Two hundred specimens of Anaspides tasmaniae were examined and one hundred and twenty-seven found to contain the encysted Trematode.

4. A systematic description of the Trematode is given.
