limestone, especially as regards the weathered specimens, the Pro- 

 ductus flint of Spitzbergen. 



Of these rocks there are the following numbers in the col- 

 lections: 



a) Of the coarse-grained limestone : 



from the Mallemukfjæld : N:os 142 and 167. 



— - Eskimo Naze : N:os 196, 197, 205b, 208 and 213 (pars). 



b) Of the fine-grained limestone: 



from the Mallemukfjæld : N:os U9, 153 and 154. 



— - Eskimo Naze: N:os 198, 203 and 204. 



c) Of the silicified limestone: 



from the Mallemukfjæld: N:o 159. 



— - Eskimo Nase: N:os 205a, 207, 210, 211, 212 and 



213 (pars). 

 These rocks contain fairly numerous brachiopods, and, in the 

 palæontologicai description it is stated in which of the specimens 

 named the respective species are found, while in the list given 

 p. 589, there is mentioned only the fossil-contents of the diffe- 

 rent kinds of rock. Regarding specimen 154 of the fine-grained 

 limestone which has given such a wealth of species that their 

 unquestionable occurrence in one stratum is specially worthy of 

 mention, see p. 591. 



B. The localities on the South Coast of Amdrup's Land. 



On the northern side of Ingolfs Fjord, on the south coast of 

 Amdrup's Land, fossils and fossiliferous rock have been collected 

 by Dr. Wegener at several places, which, reckoning from west to 

 east, can be summarized under three headings: the Western river; 

 the Eastern river and the Cape Jungersen section. It 

 should be mentioned now that Koch's map shows only one river, 

 which goes down to the shore here on the south coast of Amdrup's 

 Land, and that this river lies W. of Wegener's camping place 29 4 

 — 2 5. If the hut marked on Wegener's sketch stands for this 

 camping place, the river marked on the map would, therefore, be 

 the western one, and then we should be able to calculate the 

 distance between the Eastern and the Western rivers at 8—9 

 km. This was also ascertained by kind communication of Captain 

 Koch and amended on the map PI. XXX. These three localities, 

 consequently, lie approximately in the direction of the dip of the 

 strata, and the difference in age between the various levels can here 

 (as was the case for the localities at Hekla Sound) be noted with 

 fairly great probability, even if, in consequence of our wanting exact
