MolluscaBase name details
From editor or global species database
Nomenclature The type (preserved in NHMUK, d'Orbigny coll., and only specimen known) of this species is extremely worn and eroded, and is considered unidentifiable. Identity opinions differ between M. varia (= M. mesal) and M. brevialis. The specimen's condition prohibits any conclusive proof. It is therefore here considered a taxon inquirenda, with reference to the remark of E. A. Smith, 1915. [details]
