Summary
The diagnosis of the Favorinid genus Austraeolis Burn (1962) is completed by a study of more material, and two new species, A. westralis and A. benthicola, are described. A new Eubranchid genus Tularia is described with Cuthona bractea Burn (1962) as type species, and the Cuthonid Embletonia gracilis Risbec (1928) is recorded from Australia for the first time. A re-examination of Tergipes pauculas Burn (1962) shows it to be a mutilated specimen of Babaiella serrata (Baba , 1949).
