N:o 21 ^ b is an almost dense, gray yellow limestone, containing 

 Schwagerina princeps, and, possibly, Fiisiilina; it recalls the Henrik 

 Kröyer's islets rock containing Schwagerina, and contains of other 

 fossils nothing but an impression of a Productus. 



2ÎA с is a gray, somewhat mottled limestone containing a speci- 

 men of Productus pseudohorridus Wiman, and a specimen of a little 

 Productus and one of an Alveolites. 



'21i 6? is a gray, somewhat mottled limestone, recalling the more 

 finely crystalline limestone of the Mallemukfjæld, but with the trans- 

 ition to the more coarsely grained; a thin section showed perfect 

 agreement with this rock. Of fossils, the fragment contains a spe- 

 cimen of Productus pseudohorridus Wiman, and a poor specimen of 

 a Spirifer, or rather, perhaps, Spiriferella, and impressions of several 

 Spirifers as well as an impression of an Alveolites. 



2Ы e is a gray limestone, fairly like the fine-grained rock from 

 the Mallemukfjæld, containing partly a silicified Spiriferella and 

 also the ventral shell of a Chonetes and a Productus, somewhat 

 poorly preserved. 



21A f, g, i, h are silicified specimens of Spirifers, more or less 

 complete; the best is Spiriferella sp. (PI. XXVII, figs. 8, 9); the frag- 

 ment had some rock of light gray limestone attached and, on work- 

 ing out these silificied skeletons of brachiopod shells by means of 

 acid, there were obtained among them particles of moulds constitu- 

 ting the filling of foraminifera, for the most part Bigenerina, but 

 of other forms too, although not Fusulinœ or rotaliform foramini- 

 fera. A part of these moulds represent nearly the whole of the 

 body cavity, others again, only some few chambers.

The finds made here are derived entirely from free-lying stones, 

 and consist of loose fossils, corals, bryozoa and brachiopods, as well 

 as fragments with larger or smaller portions of rock attached. 



The rocks represented here vary very much; the commonest is 

 a white limestone, somewhat dolomitic in character, agreeing with 

 rock N:o 112 from the Cape profile. Of the rock nOAV in question 

 there are three specimens (N.os 170, 178 b and 179), which, mega- 

 scopically, are in full agreement with the Cape Jungersen section 

 rock. A thin section of N:o 178 b shows that the microscopic re- 

 semblance, too, is very striking, and that rolled fragments occur in 

 a fairly crystalline matrix, which fragments, however, are not pre- 

 sent in such a preponderant degree as in N:o 112, the matrix also 

 containing a number of smaller, irregular fragments of various organ-
