A representative of the genus Anguisia Jullien, 1882 is recorded for the Southern Ocean for the first time. A detailed description of zooidal and colonial morphology of the new species, Anguisia jullieni, is given with special regard to budding. A mode of budding identical to that in most crisiids is found in fertile erect branches. A possible way that erect branches in crisiids may have evolved by modification of peristomial budding is proposed.
