. Discovery reports. Discovery (Ship); Scientific expeditions; Ocean; Antarctica; Falkland Islands. 84 DISCOVERY REPORTS Remarks. The genus Atapozoa was erected by Brewin (1956c) for a species found at Trigg Island, near Perth, Western Australia. Atapozoa differs from Endistoma in having a stalked brood pouch, and only two anterior papillae in the larva instead of three. There were no larvae in the ' Discovery' specimens, and the brood pouch, if present at all, was in a rudimentary state. The identification therefore rests on the other characters of the zooid and on the structure of the colony
