Jurassic deposits had already been found by that time, however, 

 in the regions further north. On the second German North Pole 

 Expedition (18(>9 — 70) investigations were made on Kuhn Island 

 among others, and resulted according to Toula and Lenz 8 in the 

 discovery on the south coast of a brownish, fine-grained, calcareous 

 sandstone, which contained (lakes of mica and enclosed coal-layers. 

 In this sandstone were found a number of shells and imprints of 

 various Bivalves. A coarse-grained, fossiliferous sandstone also oc- 

 curred here. Tolla states, that these deposits probably belong to 

 the middle Dogger. A light-gray, very calcareous marl and fine- 

 grained, micaceous sandstone were found on the east side of the 

 same island 3 . As these deposits contained Aucella and others, Tolla 

 draws a parallel between them and the Aucella-hxyers in Russia 

 (Younger Jurassic and Older Cretaceous). A. P. Pavlow has shown 

 later, that the Aucellae to judge from Tolla's ligures would indicate 

 the presence of the uppermost zone of the Lower Neocomian (and 

 perhaps the Middle Neocomian) 4 . In addition to these Aucellae of 

 the Cretaceous however, Toula also mentions, among others, Iielem- 

 nites Panderianus d'Orb. from this locality. If this determination does 

 not rest on a confusion with another species, then older layers must 

 obviously also occur here, as this Belemnite is distributed in Russia 

 from the zone with Quenstedtoceras Lamberti to the zone with Cxu- 

 dioceras alternant. 



The German expedition also found Jurassic deposits at another 

 locality and that over a very extensive region, namely the whole of 

 Hochstetter's Foreland from the south point up towards Cape Seebach. 

 Owing to the very bad state of preservation of the fossils, however, 

 these deposits were misinterpreted and referred — with some doubt — 

 to the Tertiary system (Miocene). The deposits consist mainly of 

 yellowish, in part brick -coloured, line-grained sandstone with
