Two species of Megousia are described for the first time from Australia, where they occur in mid-Permian strata associated with cold water genera. One species is named M. solita n. sp., the other compared with M. yakutica (Licharev) from north and east Siberia. A new genus Kuvelousia is erected for Megousia-like forms in the Arctic Permian of Canada and Spitzbergen, with type species K. sphiva n. sp. from the Arctic Archipelago of Canada. The genus typifies the 'Svalbardian' stage (=Ufimian of the Russian platform), but is not found in the Assistance formation of Arctic Canada, correlated with the Svalbardian by some, but here considered slightly older. K. leptosa n. sp. is referred to this genus.
