Cretaceous Radiolaria.— Although certain silicified rocks in the Jurassic in Europe have furnished a large series of Radiolaria, the Australian marine limestones of this age have not yielded any of their remains up to the present. They have been found, however, in the Lower Cretaceous of Queensland, and in the (?) Upper Cretaceous of Port Darwin, N. Australia. The Radiolaria from the latter locality belong to the suborders Prunoidea,.
