Abstract
HELIXOTIONELLA gen. nov. is introduced for 3 spp. of spirally budded, free-living, lunulitiform bryozoans from Australia, H. spiralis (Chapman) comb. et stat. nov. [Selenaria marginata var. spiralis], H. rubra (Bretnall) comb. nov. [Lunularia rubra] and H. scutata sp. nov., H. spiralis, the type species, has a fossil history extending from the Upper Oligocene of Victoria, but like H. scutata, it also occurs in Recent samples from Western Australia. H. rubra is known only from the Recent of New South Wales. All species have minute colonies and the majority of specimens is shown only after detailed examination of very fine fractions of bottom sediments, which themselves include a high proportion of bryozoan skeletal material.This publication has 10 references indexed in Scilit:
