Jurassic deposits had aheady heen found hy tiiat finie, however, 

 in the regions further north. On the second (ierman North Pole 

 Expedition (f8()9 — 70) investigations were made on Kuhn Island 

 among others, and resulted according to Toula and Lexz" in the 

 discoA'ery on the south coast of a hrownish, line-grained, calcareous 

 sandstone, which contained flakes of mica and enclosed coal-layers, 

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

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

 curred here. Toula 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'. As these deposits contained Aiicella and others, Toula 

 draws a parallel between them and the Aiicella-hiyevs in Russia 

 (Younger Jurassic and Older Cretaceous). \. P. Pavt.ow has shown 

 later, that the Aiicellae to judge from Toula's figures would indicate 

 the i)resence of the uppermost zone of the Lower Neocomian (and 

 perhaps the Middle Neocomian)^. In addition to these Aiicellae of 

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

 nites Panderiamis 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 Qiienstedloceras Lamberti to the zone with Car- 

 dioceras alternans. 



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, fine-grained sandstone with
