other two localities. Where the Mollusc shells are preserved, they 

 seem on the whole somewhat more rubbed, but this probably arises 

 from the fact, that all the Fossils found here were taken in loose- 

 lying stones, of the same nature, however, as the sandstone mass. 

 The fauna from this locality is fairly rich, containing at least 26 spe- 

 cies. Here again we have Aiicella Broimi and A. Sinzooi, as also 

 Cardioceras alteriums and possibly C. Nathovsti. The discovery of 

 these fossils marks this locality as also belonging to the age of the 

 StHiuanian-Kimmeridgian. The other species (mainly Bivalves and 

 Gastropods) do not require to be mentioned in detail; but the oc- 

 currence of numerous Tancredia, Cijprind fCijprimericr?) and Astarte 

 species may be specially noticed. 



In the northernmost of the 8 sandstone regions on Store Kolde- 

 wey Island fossils are only known from the 8 localities mentioned 

 above. The fauna shows, that the sandstone must be approximately 

 of the same age at all 3 localities; it thus seems to form a con- 

 tinuous whole. Somewhat to the south of the southernmost of the 

 localities, "4. Sænkning", the sandstone comes to an end and the 

 gneiss reaches right out to the coast, forming here the northern 

 Gneiss Naze. A little further to the south the gneiss is again replaced 

 by the sandstone for a short distance, until the gneiss reappears 

 once more in the southern Gneiss Naze. The sandstone of this region 

 has the same appearance as in the northern region. On the boundary 

 of the region towards the southern Gneiss Naze , Jarnkr found the 

 sandstone lying directly over the gneiss. Of the fossils from here 

 only Macrodon Mijlii and M. Hagenii unfortunately are known, both 

 of them new species which give no information regarding the age 

 of the sandstone. We can hardly go wrong in concluding, however, 

 that this sandstone must also be referred to the Séquanian-Kimme- 

 ridgian. South of the southern Gneiss Naze we have the southern- 

 most sandstone region. As already mentioned above, the sandstone 

 here has a different character and its fauna shows, that it belongs 

 to the Callovian. 



4. H о с h s t e 1 1 e r\s F о r e 1 a n d. I have already mentioned, that the 

 2nd German North Pole Expedition found here extensive deposits of a 

 yellowish, sometimes brick-red sandstone, which contained numerous, 

 unfortunately badly preserved fossils, from which Toula and Fuchs 

 were of opinion, that these deposits belonged to the Tertiary. The 

 fossils brought home by the Danmark Expedition from this sand- 

 stone show, however, that we have to do with Jurassic deposits. We 

 have Hrst and foremost the occurrence of Cardioceras (dtenians, by 

 which the age of the sandstone is determined to the Scquanian- 

 Kimmeridgian. Of other fossils (see fauna list) may be noticed
