Hymenolepis diminuta Rudolphi, 1819; and the cysticercus of Taenia taeniae-formis (Batsch, 1786) are new host records for Australia; the same infestations with Raillietina (Raillietina) celebensis (Janicki, 1902) have also been recorded by Baer and Sandars (1956). Two new species, viz:—Choanotaenia ratticola and Hymenolepis australiensis are described. The type specimens are lodged in the Queensland Museum, Brisbane.
