Plumarella circumoperculum Cairns, 2010: 422 –425, figs. 1C, 6–7 (synonymy).

Types and Type Locality. The holotype (USNM 1072129) and paratypes are deposited at the NMNH. Type Locality: 23˚14’24”N, 163˚31’21”W (Blank Bank, Northwest Hawaiian Islands), 1373 m.

Material Examined. EX 1603-2-03, 23˚56’45”N, 166˚02’W (French Frigate Shoal, Northwest Hawaiian Is- lands), 1221 m, colony fragment, USNM 1424051 .

Remarks. This species was adequately described and figured in the original description (Cairns 2009) and thus will not be redescribed, discussed, or fully figured herein. The Okeanos site of collection is also just kilometers from previously collected specimens. The only addition to the knowledge of this species is by providing an in situ photograph of the living colony, which measures about 25 cm in width ( Fig. 1W ).

Distribution. Northwest Hawaiian Islands between Brooks Bank and Blank Bank, 432–1373 m.
