Metalaeospira, represented by one new species, has its embryos adhering to the body, but lacks any attachment stalk. Protolaeospira (inc. Marsipospira) is represented by two new species. The incubatory stalk characteristic of this genus is also found in the dextral form Protolaeospira falklandica (Pixell) (which is made the type of a new subgenus) and in Helicosiphon. A somewhat similar but funnel-like stalk is found in Romanchella, which is represented here by a new species. Southern Romanchella spp. have the collar folds fused dorsally, and a new subgenus is proposed for northern Romanchella spp. which have unfused collars and a more symmetrical distribution of uncini. A new subgenus is proposed for species of Pileolaria which lack sickle setae. The new genus represented by a single species, has '4 1/2 segments' in the thoracic region but some affinities with Pileolaria. A new species of Janua (Dexiospira) has a tube with perforated ridges. A new subgenus of Janua is erected, with a new species as type, for form close to Dexiospira but with unfused collar folds.
