Parasit. Hung. 5. 17-38. 1972. Investigations on the Eggs, the Process of Embryo-Formation and the Structure of Miracidium of Paramphistomum daubneyi Dinnik, 1962 Dr. Ottó SEY Zoological Department,Teachers' Training College, Pécs Since the first description of- the development of amphistoma /LOOSS , 1892/, several authors have dealt with the investigation of the developmental stages and biology of other amphistoma. Of the species belonging to the family Paramphistomidae , most but not all data relate to Paramphistomum cervi in the old sense /NÖLLER and SCHMID, 1928; TAKAHASHI , 1928; BRUMPT, 1929; SZIDAT, 1936; KRU3K0VA, 1957/. BENNETT /1936/ gave a detailed and full description of the developmental phases of the species he considered Cotylophoron cotylophorum , described by PRICE and McINTOSH /1944/ as a new species / Paramphistomum microbothrioi- des/ . LENGY /1960/ regarded this latter as P. microbothrium . The developmental stages of P. microbothrium were examined by DINNIK and DINNIK /1954/, LENGY /1960/, and recently by REINHARDT /1969/. The developmental stages and biology of Cotylo- phoron cotylophorum were described by LE ROUX /1930/, KRULL /1932, 1934/, SINHA /1950/, and VARMA /1961/. The full life cycles of Ceylonocotyle streptocoelium , Paramphistomum ichikawai and Calicophoron calicophorum were studied by DURIE /1953,1956/ that of Gigantocotyle explanatum by SINGH /1958/, of Paramphis- tomum ichikawai by KISILEV /1967/, of Liorchis scotiae by NIKITIN /ly6b/ and GLUZMAN /1969/, those of Ceylonocotyle scolioco- elium , Paramphistomum phillerouxi , P.daubneyi by DINNIK /1956, 1961, 1962/ and that of P. sukari by DINNIK and DINNIK /1957/. Surveys Were carried out in connection with the embryonal growth and the morphological structure of the miracidium of
