about 600 feet (188 metres) above sea-level. According to the 

 fossils, the beds were of Rhaetic-Lias age. From the 16**^10 

 the 19*^ of August was spent in collecting fossil-plants. In the 

 north side of Vardeklöft, at a height of 1750 — 1850 feet (550 — 

 580 metres), Hartz also found many fine Ammonites, Belemnites, 

 a Gastropod, vertebrae of Ichthyosaurus (according to Fraas) and 

 fossil wood. These fossils were contained in concretions in a 

 very micaceous clay-shale, which weathered easily. 



From the 15*^ to the 2И* of August Krtjüse, 0. Nordenskjold 

 and Koch undertook an expedition in a boat along the coast 

 of Jameson's Land, from North-east Bay to Cape Stewart. On 

 this expedition a light-coloured, Aucella-btu.nng sandstone was 

 found cropping out in Aucella River near the camping-place of 

 August 18**" — 19*^ in the south-west of Jameson's Land, about 

 two and a half Danish miles (18,8 kilometres) south-east of the 

 «Erratic Boulder» (see the map). 



A very exact topographical description of the regions 

 visited by the Danish expedition has been given by J. P. Koch ^). 



The Board of directors of the «Carlsbergfondet» did me the 

 honour of requesting me to undertake the examination and deter- 

 mination of the Jurassic fossils collected during the expedition of 

 1900. A casual glance through the material at once convinced 

 me of the importance of comparing these fossils with those of 

 the same age which had been derived from Central Europe. 

 1, therefore, represented to the Board of directors that it would 

 be advisable for me to make the final determination of the species 

 at Munich, where the most magnificent material for comparison 

 would be available. To this the Board of directors readily agreed 

 and placed the necessary means at my disposal; for which gener- 

 osity on their part, I desire here to express the deepest grati-
