ABSTRACT: Two small sea anemones, Octineon suecicum and Edwardsiella loveni, known previously only from scarce records in European waters, are reported from British Columbia, Canada. Both genera, Octineon and Edwardsiella were not previously reported from the North Pacific. It is speculated that both species have a wider distribution than it appears from scarce existing records, but due to specific habitat and being flat and firmly attached to bedrock (Octineon) or inhabiting deep narrow crevices in bedrock (Edwardsiella) they escape traditional collecting devices such as trawls or dredges. The phylogenetic and statistical analyses showed that the family Octineonidae is probably related with Hormathiidae.
