Some conodonts described by Tea Kolar-Jurkovsek and Bogdan Jurkovsek(2007)from the Permian-Triassic boundary section in the Ziri area of western Slovenia are revised in this paper.One specimen that they assigned to Hindeodus parvus is tentatively regarded as Hindeodus cf.scalaris Wu 2005.Two specimens that they assigned to Isarcicella sp.A is changed to Hindeodus parvus.One specimen that they described as Isarcicella lobata Perri and Farabegoli is changed to Hindeodus crenatus Wu(2006).One specimen that they assigned to Isarcicella turgida(Kozur,Mostler and Rahimi-Yazd)is changed to Hindeodus cf.parvus.Since these revisions,the three conodont zones that they defined have been correspondingly revised.Their first zone may belong to Hindeodus parvus zone, but it is not certain.Their second zone is changed to the Hindeodus parvus zone,and their third one remains as is.
