Extract

1. Neodiplostomum intermedium Pearson is recorded from four new hosts; as an adult from the water rat, Hydromys chrysogaster Geoffroy, and as a metacercaria (diplostomulum), from tadpole and adult of an undescribed tree frog, Hyla sp., tadpole of (Hyla latopalmata (Günther) Mixophyes fasciolatus Günther and frog of an unidentified leptodactylid.

2. The life cycle of Neodiplostomum intermedium was followed experimentally; the hosts were: Pettancylus assimilis (Petterd), a fresh-water limpet, as first intermediate host; tadpole of Hyla pearsoni Copland as second intermediate host; Hyla caerulea (Shaw) a tree frog, and Hemisphaerodon gerrardi Peters, the pinktongued skink, as paratenic hosts; and Rattus assimilis (Gould) and laboratory rats as definitive hosts.

3. Descriptions are given of the morphology of the miracidium, mother sporocyst, daughter sporocyst, cercaria, and diplostomulum, with special reference to the structure of the miracidium and of the cercarial tail.

4. Observations are given on the embryology of the miracidium, hatching of the egg, transformation of the miracidium into the mother sporocyst with special reference to the germinal cells, the route and manner of escape of cercariae from the snail host, the development of the diplostomulum with special reference to the reserve excretory system, and the movements of diplostomula during metamorphosis of the tadpole host.

5. The haploid chromosome number is ten, as determined from squashes of testes. One paratype and a series of experimental adults have been compared with and found different from Neodiplostomum (Fibricola) sarcophilus n.comb. The orthography and formal proposing of the names of the species of Fibricola transferred to Neodiplostomum by Pearson (1959b) are corrected.

The writer wishes to thank Dr M. J. Mackerras, Queensland Institute for Medical Research, for generously supplying water rats; Professor J. F. A. Sprent, University of Queensland Veterinary School, for his criticism of the manuscript; Mr K. Webber and his sons for their assistance in catching rats and for permission to collect snails, frogs and tadpoles from their streams; and Mr R. J. Ballantyne for technical assistance. This study was supported by a grant from the Rural Credits Fund of the Commonwealth Bank of Australia.
