At Bjøruaa in the Kovasdal 4,."> kin. from Raffen a 

 clayey steep 50—53 m> above the level of the sea contained 

 fragments of My til a s cd it lis, Lin., Ma coma bal/liica, Lin., My a 

 truncata, Lin., Buccinum ttndafum, Lin. and Balanus sp. 



At Stormo 2,5 km. from Bjørnaa a single specimen of 

 Leda pennt /a, Müll, has been found in clayey deposits about 

 BO m. above the sea level. More specimens and species were 

 not here to be found. 



A deposit of sand and gravel in the river Røvasaa near 

 Øverbækli Farm contained Pecten is/andicus, Müll., Cyfirina 

 islandica, Lin., Saxicava plioladis, Lin., Mya tmncala, Lin. 

 and Balaiuts sp. 



Between Skonseng and Guldsmedvik shells are found in 

 several places for instance in the deep railway cutting at Guld- 

 smedvik and in cuttings both above and below Prugla bridge. 

 The occurrence of shells with the richest fauna is a sand bluff 

 on the left bank of the Dunderland river 1,5 km. above Sten- 

 bækhaug Farm. From 24—30 m. above the sea level the fol- 

 lowing species have been gathered here : 



Anomia aculeata } Lin. Macon a ca /caria, ('hemn. 



Anomia ephippium. Lin. Saxicava arc/ica. Lin. 



Mytilus edit lis, Liu. Mya truncata, Lin. 



Cyprina islaiidica, Lin. Buccinum nndatnm y Lin. 

 Macmna balthica } Lin. 



Mytilus cd h lis and Macowa balthica are the predominant spe- 

 cies in the upper shell-bearing strata of the bluff. 



The said occurrences of shells between Skonseng and 

 Guldsmedvik are situated at the same level of the sea and 

 contain an uniform boreo-arctic shallow water fauna, and on 

 that account they are probably contemporary. 



All the shell-bearing strata above mentioned are younger 

 than the deepest submergence of the land for a boreo-arctic 

 fauna with snob a character cannot be thought following
