The marine Carboniferous of North east Greenl. and its Brachiopod Fauna. 533 



of small fragments of organisms, the origin of which can but seldom 

 be determined, but which, as a rule, are rounded and are probably 

 rolled, and cemented together by crystalline calcite. In the lime- 

 stone there were observable some fragments of brachiopod shells 

 and a couple of Fusulinae. In the limestone mass there occurs in 

 the joints of strata a red-brown clayey mass, pointing to shaly 

 partings. 



As far as can be judged from the diary-noles and the sketch 

 of the find-localities, the sequence of the deposits reckoning from 

 below upwards should be as follows: 10, 11, 12, 13, 14, 6, 7, 8, 9, 

 i.e., a series of strata consisting of alternate deposits of limestone 

 (predominantly dark-gray and almost black, but also reddish and 

 red-brown) and shales, in the superior part of which series there 

 exists an intermediate stratum of sandstone. 



The other material found were free-lying stones and are probably 

 derived from about the same level as 9, or probably somewhat 

 higher up in the series. Wegener speaks as follows of these pieces: 



"15. Muschel (?) in dunklem Kalk auf dem Meereise aufgesam- 

 melt. Offenbar anstehend (durch dunkle Färbung markiert) in etwa 80 m. 

 Höhe (von unten geschätzt). Etwas länger östlich vom letzten Profil. 



16. Dasselbe, grösseres Stück mit kleineren Foss. Diese beide 

 Stücke gehören also sicher über das letzte Profil. 



"17. Offenbar dasselbe, wie 16. 20minutenvon unserem Zelt als vor- 

 springende Klippe in ca. 60 m. Höhe aufstehend (die best erhaltene Steil- 

 klippe westlich unseres Lagers). Am x'Vbhang im Geröll aufgesammelt". 



Although these pieces were found free-lying, and their strati- 

 graphical position, consequently, is somewhat uncertain, still they 

 are of fairly great importance on account of the fossils they contain. 



15, is a fragment of dark-gray clayey limestone (N:o 161), or, 

 perhaps, and, equally well, a marly shale with interbeddings of a 

 somewhat more calcareous nature. On the surface the colour is 

 somewhat lighter, in consequence of weathering, and the dark colour, 

 as well as other circumstances point to some percentage of bitumen. 

 The rock contains a number of small fragments, such as of brachio- 

 pod spines, etc., and a part of a Spirifer — the umbonal portion of 

 a ventral valve. This is specially badly preserved, but both its 

 general form, the great thickness and massive build of the shell, 

 and what can be seen of the cardinal teeth and the dental plates 

 make it extremely probable that this shell belongs to Spirifer siipra- 

 mosquensis Nik., even if nothing of the sculpture of the shell is 

 visible. The petrographical character of the rock, as far as can be 

 judged by the unimportant fragment at my disposal, speaks, too, for 

 a relationship with the limestone and shale beds in Koch's section
