The triplesiid genus Streptis, hitherto unknown from pre-Llandovery rocks in Norway, is described from the Upper Ordovician unit 5a of Holmen in Asker, Oslo Fjord. The species, S. undifera (Schmidt) (syn. S. incompta Ulrich & Cooper), was previously recorded only from the Porkuni Stage (= 5b) of Estonia. The relationships of this species to other early Streptis are discussed in the light of morphological trends, and possible routes of migration of the genus suggested.
