Gravid proglottides of Raillietina (R.) celebensis (Janicki) are reported from a child in Brisbane, Queensland. Complete tapeworms of the same species are reported from Rattus assimilis Gould, from Mt. Glorious, South Queensland. A critical survey is made of all the cases previously recorded from man. Raillietina (R.) madagascariensis is for the present, regarded as a species sub judice. Raillietina (R.) demerariensis var. trinitatae Cameron & Reesal, 1951 has been raised to specific rank and named R. (R.) trinitatae (Cameron & Reesal, 1951) nov.comb. The synonyms of R. (R.) celebensis; R. (R.) demarariensis; R. (R.) alouattae and R. (R.) trinitatae, are discussed.
