Descriptions are given of two species of Haemadipsidae, one, Philaemon grandis sp. nov., the other Philaemon pungens Blanchard. The egg-capsule and newly hatched young of the latter species are also described. Limnobdella australis (Bosisto) (Hirudinidae) is recorded for the first time as occurring in Tasmania. Three new species belonging to the Piscicolidae are also described, namely Austrobdella bilobata from Rhombosolea tapirina Gunther, Trachelobdella leptocephali from the gills of Leptocephalus conger (Linnaeus), and "Ichthy-obdella" platycephali from Platycephalus bassensis Cuvier and Valenciennes. A brief description of the egg-capsules and young of Austrobdella bilobata is also included. In addition, some account is given of specimens of Branchellion parkeri Richardson,taken from Raia lemprieri Richardson, Pristiophorus sp. and Dasyatis sp. Further information concerning Pontobdella tasmanica (Hickman), its occurrence on a piece of seaweed, and also on a skate, is provided. Three members of the Glossiphoniidae, namely, Glossiphonia tasmaniensis sp. nov., Glossiphonia australiensis Goddard, and Placobdella bdellae sp. nov., are described, the last named species occurring in the buccal cavity of the pouched lamprey Geotria australis Gray. The structure of the nephridia in Glossiphonia australiensis Goddard is given for the first time.
