Abstract
Tylospira, the Australian representative of the southern hemisphere family Struthiolariidae, comprises nine fossil species ranging in age from Early Miocene to Late Pliocene and Pleistocene, and one species living off the coast of New South Wales. Tylospira glomerata, T. incilata and T. puteana are newly described. Singletonaria Marwick 1952 is synonymised with Tylospira Harris 1897.
