of a species belonging to the genus Coeloma, I shall in the 

 following term this bed the Coeloma-hed. 



3) A greenish sandstone with wood and fossil animals. 



4) A sandstone which in some places was quite filled up 

 with pelecypods and gastropods. 



On account of the frequent occurrence in this bed of a 

 species of Cyrena, I shall in the following pages term this 

 bed the Cyrena-bed. 



Of the stratigraphical relations between the Tertiary sedi- 

 ments and the basalt nothing is known beyond what has been 

 related above, but as farther to the NW. considerable beds of 

 sandstone were seen in the basalt-cUff, . it may be reasonably 

 supposed , that the fossiliferous deposits of Кар Dalton form 

 subordinate beds in the basalt. This agrees with the fact that in the 

 above mentioned, more northerly situated Tertiary-localities, with 

 the exception of Hochstetters Vorland, the Tertiary deposits 

 are in contact with the basalt. 



Professor N. V. Ussing who has been kind enough to 

 examine the Tertiary rocks occurring at Кар Dalton, has, as 

 the results of his examinations, sent me the following commu- 

 nications : 



«By an examination through the microscope of the Tertiary 

 «rocks brought home by the Amdrup expedition in 1900, 1 have 

 «tried to determine the question of the origin of the material. 

 «As the age of these fragmental rocks in relation to the basalt 

 «formation has not been finally decided at the place in question, 

 «it might be supposed that the material of these sediments 



«a) originates exclusively from the destruction of Archæan 

 «rocks, or 



«b) originates exclusively from the destruction of the vol- 

 «canic rocks (basalts etc.) of the district, or finally 



«c) that they contain detritus both from the Archæan 

 «formations and the basalt formation.»
