During a period of many years, Mr. Luke Gallard, formerly an inspector belonging to the Department of Agriculture, New South Wales, made a collection of parasites, chiefly nematodes, from the fauna of the Gosford and Kenthurst districts where his official duties lay. This collection was placed in the Australian Museum and was recently forwarded to us for identification. Our thanks are due to the Director, Dr. A. B. Walkom, for the opportunity to study it. We also acknowledge assistance from the Commonwealth Research Grant to the University of Adelaide. All material, including types of the new species, is housed in the Museum, the registered numbers being indicated.
