title: Sarcocystis booliati n.sp. and a parasite of undetermined taxonomic position, Octoplasma garnhami n. gen. n. sp., from the moonrat, Echinosorex gymnurus.
abstract: Sarcocystis booliati n.sp. is described from the moonrat Echinosorex gymnurus (Mammalia, Insectivora) from West Malaysia. The cysts are very thin-walled, not visible to the naked eye, and have no trabeculae or cytophaneres. They are found in skeletal but not heart muscle. The zoites are small, 5-8 by 2-3 mum with a mean of 6.5 by 2.2 mum, in dry fixed smears. Octoplasma garnhami n.gen. n.sp., a parasite of undetermined taxonomic status but belonging to the Coccidiasina, Apicomplexa, is also described from the same host. Only schizononts and pseudocysts with typically 8 zoites, have so far been seen in monocytes of the spleen and liver. The zoites are large, 15 by 3 mum and have a distinct nucleolus even in dry-fixed smears.
