that the crystalline calcite in the "pebbles' has a fairly evenly 

 distributed reddish pigment. 



Of megascopic fossils this rock contains a couple of specimens 

 of a rugose simple coral, and several specimens of Schwagerina 

 princeps. 



A fragment that is in perfect agreement with N:o 191, obtained 

 on Henrik Kröyer's islets, is N:o 178 a, which is an almost dense 

 or very finely crystalline limestone, containing Schwagerina princeps 

 and also the same coral as N:o 191. 



There is also a trunk of a coral, probably Petalaxis or Phil- 

 lipsastraea {N:o 195) in a sandy limestone. Both the coral and the 

 rock present a great resemblance to the corals that J. G. Anders- 

 son collected at Beeren Eiland on the slope of Fogelberget towards 

 Ymersdal, in sandstone with beds of coral-limestone, belonging to 

 the lower part of the Upper Carboniferous. 



Finally, from this locality may be mentioned two entirely sili- 

 cified corals {N:os 175 and 181), a species of Sijringoporidœ and a 

 rugose simple coral. 



Of the collections made at the easternmost localities on Am- 

 drup's Land, special attention is drawn by the rocks containing 

 Schwagerina princeps Moll., as, of course, the occurrence of this species 

 of FasulinidcL' definitely determines them as belonging to the upper 

 part of the Upper Carboniferous series. Schwagerina princeps has 

 been found both on Henrik Kröyer's islets and on the mainland 

 behind, and at Sophus Müller's Naze. 



D. Summary of the Carboniferous deposits of 

 North-east Greenland. 



Having, in the preceding pages, given a detailed description 

 of the various kinds of rock belonging to the Carboniferous of 

 North-east Greenland, and also of the stratigraphical conditions under 

 which they may be supposed to occur, we shall now attempt to 

 collect these deposits into larger groups and to compare the different 

 formations that have been observed at the various localities and in 

 the several sections. 



This work, too, will be restricted by the character of the ma- 

 terial, as a consequence of the unfavourable conditions under which 

 it was obtained.
