Available specimen (BL ca. 4 mm) from Macquarie Island (30 m, R/V Dmitriy Mendeleev, 21.01.1976) was very damaged and it was only possible to study pieces of head and intermediate valves and the radula by SEM. It turned out that the tegmentum is smooth with very small, narrow grooves and with megalaesthete pores only, which are arranged in quincunx. The studied specimen has a radula with a length of about 1 mm and 24 transverse rows of mature teeth. The cusp of the major radular lateral tooth is tridentate, the denticles are almost of equal size. The specimen from the USNM sample with BL 6.0 mm has 7 gills arranged from valve six to anus.
