Distribution and depth range

West Kyushu, Eastern Coast of Japan from South Kyushu to Hokkaido and including Sagami Bay ( type locality), east of Kurile Islands. GBIF (2025) records extend further this distribution to the Aleutian Islands and Alaska, and to Mayotte. This latter record is particularly distant from the known distribution. I could examine part of this material (specimen MNHN-IU-2009-3005), but did not identify any obvious morphological difference from Loman’s (1911) illustrations. However, these are insufficient in details and the original material should also be reexamined. Minimal known depth range 40–869 m? Some previous authors (starting from Utinomi 1971) extend this depth range up to 20 m but I have not found any corresponding record in the literature.
