Remarks: The capitulums of this specimen (QM G337590) were not swollen, while capitulums of the examined specimens of Epizoanthus fatuus (NSMT-Co 1757, NSMT-Co 1758) were swollen when contracted. On the other hand, numbers of tentacles and mesenteries were the same between QM G337590 and the examined specimens of E. fatuus . Therefore, we here preliminarily identify the examined specimen as Epizoanthus aff. fatuus .
