The Primordial rocks of the Island of Oland have, been made known 

 chiefly by the labors of M. Sjogreii. 



The Paradoxides beds are divided by him into two divisions, of which 

 the lowest consists of arenaceous flagstones this is characterized by 

 Paradoxides tessini; the upper consisting of greenish shale with inter- 

 calated calcareous and arenaceous beds with Paradoxides olandicus. The 

 strata with P . forchhammeri (that there occurs) making a third division. 

 They are immediately overlain by the Olenus beds.
