in oiir palæozoic series was discovered here. Hy dint of strenuous labour 

 r succeeded in malcini;" a good collection in i</Xj, this consisting of 

 Gigantostracs, IMiyllocarids, and Ostracoderm fishes. As the fish fossils 

 were found to be unusually well preserved, I began a more extensive 

 quarrying of the band last Summer (iQio), and I collected a large 

 quantity of material, which in addition to a number of fragments contains 

 many excellent specimens. As I intend to continue the work of collection 

 next summer, and as the palæontological description will occupy con- 

 siderable time, I propose to give now a preliminary report of the new- 

 discovery and its significance. At the same time some new observations 

 of the development , of the sandstone series in Ringerike will be given. 

 In a later paper I hope to be able to offer a minute description of the 

 new fauna and of the sandstone series in general.
