This species has been typically found on soft muddy bottoms between 250 and 500 meters in a small area off Western Australia south of Broome and northwards to the Ashmore Reefs, off southern Japan and in the Central Indo-West Pacific. I highly doubt the locality of Southern Japan and Indo-Pacific as these maybe misidentified from the more common congener B. teramachii. It defers from it from the smooth shell and other differences, apart from the locality. The common B. teramachii may also exhibit smoother shell than normal thus misidentified for this species.
