The presentation recently to the Australian Museum collection of a mollusc trawled off Cape Everard, Victoria, by Captain K. Moller, a keen collector who has given much valuable material to the museum, has disclosed some interesting facts concerningthe generic and specific name of a similar species from Backstairs Passage, St. Vincent Gulf, South Australia.
Basedow gives the new specific name contusiformis (PI. xxvi, figs. 6-9) and colour variety names testudinis, pulchra, and labyrinthine to a large naked mollusc dredged in South Australia, and places it in the genus Caledoniella Souverbie, a genus made for a small, snail-like, parasitic mollusc from New Caledonia, described. as fragile, with fine radiating striae, and covered with a fine yellow epidermis.
