An ascaridoid nematode Cotylascaris thylacini is described from the thylacine or Tasmanian marsupial wolf. Only female specimens were available. The new genus is distinguished by two cup-like structures on the anterior margin of each lip. It is suggested that these structures may comprise an adaptation to the unusual form of the intestinal wall in the thylacine. The significance of the ascaridoid nematodes of marsupials is discussed in relation to the possible route of entry of marsupials into Australia.

Financial assistance for this study was provided under grant No. 16 from the Australian Research Grants Committee.
