Subject is a taxon inquirendum and not notable. Although validly published, the species is not accepted, and not a synonym of another species that it can be redirected to, merged with, or moved to.

• Delete. WoRMS lists Higo et al. "Catalogue and Bibliography of the Marine Shell-Bearing Mollusca of Japan" as the basis of their record. Download Higo's book here. In the first page of the introduction Higo notes: "One unavoidable consequence of basing a work of this kind primarily on literature rather than on independent field and laboratory research is that the number of species recorded will almost certainly exceed that actually present in Nature." On the second page of the introduction, Higo devotes several sentences to discussing the work of Arthur Adams, describing it as a "major problem" due to the "brevity and vagueness of many of whose descriptions was already the target of scathing criticism [in 1895]", Higo goes on to discuss some successes confirming species described by Adams, and conclude with "even the most optimistic reviewer of Adams’ work must concede that the types of many of his species are probably lost". This species was described by Arthur Adams. Higo's treatment of the species is minimal, but gives the distribution as "recorded only from type locality" (which is fair to interpret as "nobody has collected a snail identified as this species since Adams"). WP:SPECIESOUTCOMES is predicated on an animal species having a valid name; many of the names authored by Adams aren't considered valid. Delete this and any other articles on Japanese molluscs described by Adams and with status as taxa inquirenda on WoRMS and with Higo as the basis of the WoRMS record.
