513 STRONGYLATE NEMATODES FROM MARSUPIALS IN NEW SOUTH WALES. By T. Harvey Johnston and Patricia M. Mawson, University of Adelaide. (Sixty-six Text-figures.) [Read 25th October, 1939.1 The present communication is the fifth of a series dealing with the nematode parasites of Australian marsupials, the earlier papers giving accounts based largely on material from Queensland and Central Australia. Twenty-five species are proposed as new and are distributed amongst eleven genera, three of which (Cyclostrongylus, Parazoniolaimus, and Maplestonema) are new. Types of new species described in this report are deposited in the South Australian Museum, Adelaide. This investigation has been made possible by the Commonwealth Research Grant to the University of Adelaide. We desire to acknowledge assistance in regard to material from Professor J. B. Cleland; Messrs. L. Gallard, Narara; A. S. Le Souef, Director, Sydney Zoological Gardens; and W. L. Rait, Adelaide. Much of the material was collected by the senior author between 1908 and 1911 during his residence in New South Wales. The locality quoted as Lower Hawkes-bury is in the vicinity of Milson Island and the township of Hawkesbury River. List of Hosts and Parasites dealt with in this Paper.
