82 (d) Australia: D. potatoY'UflJ is the only species tha.t has been recorded gro\'IIing in Australia. Reports of D. antarctica are of drift specimens (Moore and Cribb 1952:1100; Kenneally 1972:78) 0 D. potatol'1Am is to the southeast region on coasts that Bennett and Pope (1953) called cool temperate, Lucas (1936:81) gave the range as Tasmania and Vic·torian coastline bet.ween Cape !-1m·,e and Cape Northumberlcmd. Bennett and Pope: (1953) and Womersley (1959) described a Hider range on the mainland coast. According to these authors the species extends from Robe in South Australia to Bermagui in Ne\Il South Wales. There are various reports of D. potat~um on ~he Tasmanian \
