The first published descriptions of Tasmanian Cambrian trilobkes are given. Two new species, Opsidiscus argusi and Schmalenseeia gostinensis, are described from a fauna, the age of which is probably either that of the latest Middle Cambrian Lejopyge laevigata III Zone or the Middle Cambrian/Upper Cambrian Passage Zone. Opsidiscus argusi has well developed schizochroal eyes, recorded for the first time in this genus. The genera Opsidiscus and Schmalenseeia are reviewed. Opsidisus is placed in the Pagetiidae. Schmalenseeia acutangula Westergard is in need of revision and should be removed from Schmalenseeia.
