A new nematode belonging to the family Physalopteridae was obtained from a primitive, deep-sea frill shark, Chlamydoselachus anguineus, caught off the Pacific coast of central Honshu, the main island of Japan. On the other hand, the larva was also found lying on the brain of a deep-sea bristlemouth, Cyclothone atraria, taken from the Pacific coast of northern Honshu. The life cycle of this nematode is briefly speculated. The nematodes were preserved in 70% ethanol and cleared in glycerin or Gater's solution. The specimens are deposited in the collection of the National Science Museum (Nat. Hist.), Tokyo. We are grateful to Dr. Toru TANIUCHI, Faculty of Agriculture, University of Tokyo, who afforded an opportunity to collect the parasites of the frill shark. Thanks are also due to Dr. Elmer R. NOBLE, University of California, and Dr. Yuzo KOMAKI, Far Seas Fisheries Research Laboratory, for providing valuable specimens.
