NOTES ON SOME SPECIES OF NEMATODA FROM KANGAROOS AND WALLABIES, INCLUDING A NEW GENUS AND THREE NEW SPECIES.

Abstract

A large number of nematodes from Protemnodon rufogrisea, P. bicolor, P. dorsalis, and Macropus canguru, from southern Queensland, M. robustus from Western Australia, and Megaleia rufa (? locality) have been examined. The species described in this paper are: Pharyngostrongylus macropodis Yorke & Maplestone, P. kappa, sp.nov. (syn. P. macropodis in part), P. eta Johnston & Mawson, P. lambda, sp.nov., Rugopharynx epsilon (J. & M.), R. delta (J. & M.), R. zeta (J. & M.) (syn. R. longibursaris (Kung)), R. theta (J. & M.), Coronostrongylus coronatus J. & M.; a new genus is proposed, Oesophagonastes, with type O. kartana syn. Spirostrongylus kartana Mawson to include O. parma syn. Pharyngostrongylus parma J. & M., O. gallardi syn. P. gallardi J. & M., and O. leptos, sp.nov.Most of the parasites were sent for examination by Dr M. J. Mackerras, then of the Queensland Institute of Medical Research. Those from Western Australia were from Dr T. Ealey of the Zoology Department, Monash University, Victoria, who was working on Macropus robustus in the north of that state. I am most grateful to both of these helpers.
