Two new species of Paramphtstomum from cattle are described, namely, P. hiberniae n.sp. and P. scotiae n.sp., first collected from Irish and Scottish cattle respectively.A brief account of gametogenesis and early cleavage division is given.The chromosome number for P. scotiae is n=8, 2n=16, for P. hiberniae no definite number is given but it is believed to be n = 8 (6–8), 2n=16 (12–16). Notes are made on some specimens received from the Netherlands and France.P. hiberniae and P. scotiae are compared with P. cervi and P. leydeni.
