also giving a new proof of how extraordinarily alike is the fauna) 

 developement in the Upper Carboniferous throughout Ihe vast Russian- 

 Arctic realm. 



Of considerable interest is the discovery of effusive rocks above the 

 fossiliferous chert-bearing limestone at Svarle Vaeg, and as I hey are 

 covered by sedimentary rocks of the same kind, there can be no doubt 

 that also in the far north volcanic activity is marked in Upper Carboni- 

 ferous time. Besides tuffs, lavas are found, described by BUGGE in 

 n Petrographische Resultate, etc.", p. 36. 



Mesozoic. 



Of great importance is the discovery of wide-spread Mesozoic beds 

 that were previously known only in a few localities in the islands lying 

 to the south-west of Ringnes and Heiberg Island (Prince Patrick Island 

 and others). 



From the shores of Eureka Sound and adjacent district farther north, 

 fossils were collected in several localities. The fossil faunas were studied 

 by Prof. E. KITTL, who has published a paper M Die Triasfossilien vom 

 Heureka Sund". (This report no. 7, 1907). 



Arranged according to locality the fossils described by KITTL are 

 the following: 



1. B'rom calcareous shale and limestone at Blaafjeld (Blue Mountain) 

 to the north of Eureka Sound: 



Halobia Zitteli LINDSTR. 

 *Daonella Frami KITTL. 



2. From blackish calcareous shale at Ammonite Mountain, Bjernekap- 

 landet: 



Discina cf. Barrentsi BOHM. 



Halobia Zitteli LINDSTR. 

 *Avicula polaris KITTL. 



Gryphaea Skuld BOHM. 

 * Protrachyceras Sverdrupi KITTL. 



Protrachyceras cf. Sverdrupi KITTL. 



Protrachyceras aff. Bichthofeni MOJS. 



3. From calcareous arenaceous shale at the depot, Store, Eureka 

 Sound: 



Halobia Zitteli LINDSTR. 

 *Avicula polaris KITTL. 

 Pseudomonotis (?) sp.
