Description
Marine biological studies of polyzoa [brozoa] dredged from Moreton Bay, Moreton Island, Queensland, Australia. The author does not identify the species but characterises them as having “structures observable in those of Vesicularia and Bowerbankia”. The creatures are presented at natural size (figure a) and under magnification (figures b-g).
These specimens were described by the author aboard HMS Herald in April 1856 as the vessel was engaged in survey work in the South Pacific. The author, John Denis Macdonald was assistant surgeon on the ship.
