parts of Jameson's Land together with Dr. Deichmann and 

 during excursions from our landing places during a boat- 

 journey along the W. and S. coasts of the same land. In the 

 former case 1 could establish the fact that within the whole 

 district traversed by me, up to the so-called Fossil mountain M, 

 the rock consists of monotonous, light Jurassic sandstone, in 

 which fossiliferous banks are not rare, and ammonites are now 

 and again so plentiful that the ground at the weathering of the 

 rock is thickly strewn with them for long stretches^). In the 

 W. parts of Jameson Land the rocky foundation is covered by 

 such deep quaternary beds that it could not be observed any- 

 where, but we may presume that the Jurassic beds continue 

 here and on the SW. side of the land they were also found, 

 though only in a few places in the banks of large rivers. Only 

 in one place did I find fossil remains, which are, however, of 

 great interest and consist chiefly of Aucella Pallasii Keys; 

 close by occurred also badly preserved ammonites. 



The petrifactions collected by Hartz and myself, have been 

 described by Victor Madsen^), to whose work I need only 

 refer. It appears that the Cape Stewart beds, which have long 

 been known, belong to the Callovian and are found the higher 

 up the further N. one reaches; here belong presumably the 

 ammonites (among others Macrocephalites Pompeckji 

 Mads.), which I found at a height of about 500 metres above 

 the sea, right inside the innermost bay of Hurry Inlet. Under- 

 neath this series were found in Nathorst Mountain fossil remains 

 that are assigned to upper Bajocian or Lower Bathonian. On 

 the other hand the beds I came across, both furthest SW. and 

 NW., are essentially younger; the former (Aucella- beds) 

 belong to the Lower Volgian, the latter are considered by

very little material could be collected, unfortunately.
