Remarks.—The species Hirnantia sagittifera from the East Baltic has been recently described in a separate paper ( Hints et al. 2012) and need not be repeated here.
Stratigraphic and geographic range.— The Hirnantian Stage, Upper Ordovician. This cosmopolitan species is the eponymous taxon for the Hirnantia brachiopod fauna. The species is common in both the typical and atypical Hirnantia faunas and has a near global distribution ( Rong and Harper 1988). In Baltoscandia it occurs in Norway ( Cocks 1982), Sweden
Bergström 1968), Estonia, Latvia (this paper), and Lithuania
