Remarks
Off Choshi, Mouth of Tokyo Bay, and Sagami Bay have been known as
locality of this species. Recently, it came to be collected from Sotobo
and Tosa Bay. The locality of shown specimen is Mouth of Tokyo Bay.
I think that the color of the beyrichii in the Mouth of Tokyo Bay is thicker than
other localities.
