A new protozoan parasite from a Bdellid mite

Abstract

The parasite here described was found occurring in one of four Bdellid (Biscirus intermedius) mites from Tasmania. The mite containing the parasite was kindly placed at my disposal by Mr. H. Womersley, A.L.S., F.E.S. The parasite was present in the abdominal region of the mite, the exact position being shown in the figure. It was reniform, and was approximately one-eighth the size of the animal. The general appearance was rather Sarcosporidian in nature, under low power being somewhat granular. Under higher powers no sign of spores could be observed, the granules appearing purely protoplasmic in nature.
