Remarks. Zibrowius (1973a) established the genus Bathyvermilia for the deep-water Vermiliopsis langerhansi Fauvel, 1909 and the newly described Bathyvermilia challengeri (new name for Placostegus ornatus not Mörch, 1863 but sensu McIntosh, 1885). Later, three species (see list below) were added. Zibrowius (1973a) provided a table summarizing the differences for the genera Bathyvermilia , Metavermilia , Pseudovermilia , and Vermiliopsis , previously all united under Vermiliopsis .
