| Abstract |
Two piscicolid leeches, Notostomum cyclostomum and Johanssonia arctica, were found on the exoskeleton of snow crabs Chionoecetes opilio from the continental slope in the Sea of Japan off Kyoto, Japan. The finding of J. arctica constitutes the first record from the Sea of Japan and extends its southernmost limit of distribution from Funka Bay (Hokkaido, western North Pacific) to the Sea of Japan off central Japan. Chionoecetes opilio is recorded as a new substratum for J. arctica in Japan to deposit its cocoons. The external morphology of the leeches is briefly described. The cocoons of N. cyclostomum mostly occurred on the dorsal carapace surface, whereas those of J. arctica on the ventral femoral surface of the walking legs.
