The fossil species in this place are thus fevv in num ber but 

 they are, nevertheless, highly interesting when compared with 

 those of the surrounding district. 



In order to obtain still further material for correla- 

 tion we are to extend our researches tovvards the north, or 

 north-northeast from the railway-station of Spydeberg. In the 

 surroundings of the railway-station itself we meet with a very 

 fine sand or even sandy clay of a light yellowish-grey colour. 

 To a depth of about one meter and a half we meet with the 

 same clay. Sometimes clay-concretions may be seen in the clay 

 but no fossils could be detected nor any reaction to HC1. In 

 the summer of 1911 I had an opportunity to examine the clay 

 deposits in a place in which the foundation work for the con- 

 struction of a central station of electric power transmission was 

 just going on in the river near Berger some four kilometres to 

 the north-northeast of the railway-station of Spydeberg. In the 

 channel of the river we meet with very fine ice-scratched rocks 

 that proved to be nicely striated or even furrowed with glacial 

 grooves or canals. Giants' cauldrons are not uncommon. The 

 glacial canon proved to be filled with ordinary ground-moraine of a 

 bluish-grey colour, the upper part of it being of a more sandy 

 character and yellowish-grey colour. Upon this ground-moraine 

 and fluvio-glacial material rests a clay deposit of a grey colour 

 or in some places with a yellowish or even wavy dash of 

 colour. This clay deposit was much mixed up with sand and 

 gravel and even stones, and in some scattered places a slight 

 reaction to HC1 might be seen. In this layer the following 

 fossils were found: — 



Area glacialis Gray of a small and ovate type. Length 

 11 mm., and height 6 mm. 



Portlandia lenticula Møll. of an ovate shape and length 

 5 mm. 



This clay-layer is covered with an upper one of a bluish- 

 grey or yellowish-grey or even wawy or streaked colour. This 

 clay is rather fine and rich in fossil, viz. —
