Abstract
The material listed here was obtained by Dr. W. K. Blackie and Mr. W. A. McDonald during a helminthological expedition from the London School of Hygiene and Tropical Medicine to Southern Rhodesia in 1930–31. The writer is indebted to Professor R. T. Leiper for the privilege of examining and reporting on this collection of parasites. The domestic animals in question are sheep, goat, pig and cattle and although they appear to have produced no forms new to science, it is believed that the publication of this collection, inasmuch as it appears to be the only one of its kind from Southern Rhodesia, is a contribution to our knowledge of an important parasitic group.
