The cysticercoids of Dicranotaenia coronula and Microsomacanthuscompressa are recorded from the stomach contents of Lymnaea peregra and L. stagnalis, and M. compressa also from L. palusiris at the Wentloog level, near Cardiff, South Wales. The cysticercoids of Haploparaksis cirrosa and Kowalewskius parvitla found in the botryoidal tissue of Erpdbdella octoculata from a pool at Llynheilin, New Radnor, are described. The adults of K. parvttla reached maturity in 17 days, in a duckling, and the egg capsules produced contained approximately 100 oncospheres in each.
