IXCERTAE SEDIS. Family Anomalopidae. Two genera of deep-sea Perciform fish maybe provisionally placed here ; their osteology is still unknown. Theyare remarkable for the possession of a large movable phosphorescentorgan below the eye ; it can be turned outwards when lit up and in use,and turned back into the orbit when extinguished.
