The marine Carboniferous of Nortli-east Greenl. and its Brachiopod Fauna. 521 



shore, in the same locality, in a free-lying boulder of similar rock 

 {N:o IM), there has been discovered a Spirifer Frilschi Sghellw., very 

 badly preserved, it is true. 



Close by, higher up on the cliff, at a level of 275 metres above 

 the sea, there have been collected specimens of the solid rock. 

 Here we find the same bituminous limestone as at 240 metres, 

 but at the higher level the rock contains, in addition to crinoid 

 stems, numerous small Fiisulinae. Among the larger fossils there 

 come from this level the specimen, already mentioned, of Spirifer 

 supramosquensis Nik. {N:o 152), and also Spirifer fulmari, n. sp. 

 {N:o 166). In this locality, too, the bituminous, somewhat shaly 

 limestone seems to stand in connection with a more evenly bedded 

 and denser limestone {N:o 165). This kind of rock somewhat gives 

 the impression of being silicified, and contains a piece of a brachio- 

 pod shell which can very well belong to Sp. supramosquensis, and 

 of smaller fragments of fossils, in addition to crinoid stem-joints 

 pipes, brachiopod spines and fragments of Bryozoa, a number of 

 Foraminifera — mostly Fusulinae, but also some few specimens of 

 Bigenerina and Tetrataxis. 



Somewhat to the eastward of Koch's section lies the Conglom- 

 erate section, from which there also exists a series of specimens. 



The Conglomerate section. According to Dr. Wegener's 

 diarynotes, the lower part of the slope, up to 120 metres above the sea 

 consists of detritus and snow which cover shale and shaly sand- 

 stone. At the level mentioned we find a dark-red, stratified con- 

 glomerate containing pieces of rock as large as a fist, pebbles of 

 Archæan rock. There is only one little specimen of this conglomer- 

 ate {N:o 185) which, besides, is unfortunately greatly weathered, so 

 that it is impossible to draw as safe conclusions from it as is desir- 

 able. The conglomerate seems to be composed of a not very speci- 

 ally well-rounded weathered detritus, the grains of which are of 

 greatly varying size; in the specimen at hand they varied from the 

 size of a hazel-nut to that of a mustard-seed. The greater part ot 

 the pebbles consist of quartz, but some appear to be granite, or 

 some other crystalline rock of a fairly light colour. The weathered 

 part of our specimen is red, and the grains are so loosely cemented 

 that the rock can easily be crumbled; the interior, sound part is 

 somewhat lighter in colour and presents the conglomerate grains 

 inbedded in a white, opaque matrix, which is crystalline and pos- 

 sesses a lustre like that of mother-of-pearl or silk; it is not very 

 hard and is insoluble in acids. By means of chemical and optical 

 examination it proved to be baryte. The unimportant amount avail- 

 able of this rock does not allow of any account being given of the
