Nipponophyllu m antarcticum Hartman, 1978: 142, Žgure 9a–d.
Material examined. Holotype (USNM-46745), Weddell Sea, Antarctic.
Remarks. Examination of Hartman’s type shows that it does not belong to Notophyllum. In view of the presence of a median antenna, the absence of notoaciculae, and its prolonged supra-acicular neuropodial lobes, we conŽrm Pleijel’s (1991) suggestion that it belongs to Sige Malmgren, 1865.
