DISTRIBUTION.—This frequently collected species is known only from the islands of Japan. It has a wide depth distribution, previously from the littoral to 300 meters, but with these records it is extended to 479 meters. The species has not previously been taken as far north as the above Akkeshi record, which points toward the species occupying both cold and warmer waters within and outside the Kuroshio Current zones.
