Of considerable interest is the discovery of effusive rocks above the 

 fossiiiferous chert-bearing hmestone at Svarte Vaeg, and as Ihey are 

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

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

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

 „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 „Die Triasfossilien vom 

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



Arranged according to locality the fossils described by Kittl are 

 the following: 



1. from calcareous shale and limestone at Blaafjeld (Blue Mountain) 



to the north of Eureka Sound: 



Halohia Zitteli Lindstr. 

 * Daonella Franti Kittl. 



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

 landet: 



Discina cf. Barrentsi Bbhm. 



Halohia Zitteli Lindstr. 

 *Avicida polaris Kittl. 



Gryphaea Skuld Bohm. 

 *Protrachyceras Suerdrupi Kittl. 



Protrachyceras ef. Sverdrupi Kittl. 



Protrachyceras aff. Bichthofeni Mojs. 



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



Sound: 



Halohia Zitteli Lindstr. 

 'Avicula polaris Kittl. 

 Pseudomonotis {'?) sp.
