From the shrimp, Pandalus goniurus, taken in Aniwa Bay, Sakhalin, USSR, two encysted digenean metacercariae were described. One of them frequently occurred in the body muscles of the posterior cephalothorax region of the shrimp. It was found out to be the metacercaria of Podocotyle reflexa. Its experimen-tally induced infection to fish, Tribolodon hakonensis, met with failure. Some of the an-atomical features observed were newly added to USPENSKAYAS (1963) description of the metacercaria of P. reflexa. The life-cycle of P. reflexa in Aniwa Bay was briefly discussed. The other metacercaria was rarely found in the dorsal heart wall of the shrimp. It proved to be an unidentified Podocotyle species metacercaria. The well-developed meta-cercaria did not represent in the progenesis. In connection with the identification of the metacercaria, the species of Podocotyle which had been recorded from the northern Far-East seas were discussed.
