One complete specimen (Sta. 216) has variable segment length: chaetigers 1–12 are medium sized, chaetigers 13–28 are short, and thereafter are elongated (or badly preserved) from chaetiger 28. One of the specimens that was included in the original description (station 767) does not belong to this species; it has straight neurohooks with very short anchylosed articles throughout the body, and three longitudinal series of black papillae; it is an undescribed species of
