Notes on Australian athecate hydroids
Abstract
The following notes refer to two Athecate Hydroids—(i) the fresh water Cordylophora lacustris Allman, from the Myall Lakes, New South Wales, and (ii) the marine Bougainvillia ramosa (van Beneden) from Port Jackson, Sydney.
The occurrence of Cordylophora lacustris in the Myall Lakes is extremely interesting, since this widely distributed colonial Hydroid has been recorded previously in Australian waters only from Parramatta, near Sydney (Whitelegge and von Lendenfeld), and from a small tributary of the River Inglis, between Wynyard and Flowerdale, Northern Tasmania (Flynn).
The marine Hydroid, Bougainvillia ramosa (van Beneden), which occurs abundantly on the piles of the wharf at Watson's Bay, Port Jackson, is the first representative of the genus Bougainvillia to be recorded from the coastal waters of New South Wales.
