A single metacercaria of the genus Proctoeces ODHNER (Fellodistomatidae: Trematoda) from an abalone, Haliotis discus hannai INO (Archaeogastropoda: Gastopoda), is discribed. The metaercaria was found in a new locality in the northern regions of the Sea of Japan and on a new second intermediate host for the genus Proctoeces. The abalone was collected along the shores of Funadomari, Rebun Island, Hokkaido. The metacercaria, from between the epipodium and mantle of the host, was unencysted with well developed internal organs but was observed to be not of the progenetic form. Althogh it seemed to be morphologically related to P. maculatus (LOOSS) ODHNER or to P. subtenuis (LINTON) HANSON, specific identifications did not prove fuccessful because of only a single specimen and its lack of eggs.
