Specimens of Girvanellu sp. are described for the first time from the Oslo region, Norway. The specimens discussed here occur in Lower Llandoverian biomicrites in the central part of the Oslo region (Bærum/Asker). The distinct association between Girvanella sp. and other faunal elements in the succession provides important new information on the depth ranges of Lcwer Silurian brachiopod communities.

Recent karst forms in gypsiferous beds are reported from Mathiesondalen in Central Spitsbergen, where several sinkholes (do lines) and swallow holes have been formed after the deposition of Holocene raised beach sediments. The bedrock of the area is mostly interbedded gypsum/anhydrite and dolomites of the Carboniferous Ebbadalen Formation.

Occurrence of Salterella rugosa Billings on Nordaustlandet, Svalbard, is reported for the first time. The rocks that produced these fossils belong to the upper part of the Kapp Sparre Formation. This unit can be correlated with the Oslobreen Dolomite in Ny Friesland (Spitsbergen, Svalbard) from which the same species has been reported earlier; these fossils have not been illustrated previously. In both areas many specimens are poorly preserved, and it is becoming increasingly evident that the difference between Salterella and Volborthella simply may be the result of loss of the outer shell in the Volborthella.
