1913] TERRACES AND LITTORAL PHENOMENA IN RAUER 7 



In this uppermost terrace the following remains of a former 

 shallow-water life were found: — 



Ostrea edulis Lin. 

 Vota maxima Lin. 

 Mytilus edulis Lin. 

 Gardium echinatum Lm. 

 Cyprina islandica Lin. 

 Astarte sulcata da Costa. 

 Mya arenaria Lin. 

 Littorina littorea Lin. 

 Buccinum undatum Lin. 

 Nassa reticulata Lin. 

 Polytropa lapillus Lin. 



Mya arenaria has of course been vvashed up during more 

 stormy weather, when a rough sea has rolled heavy waves 

 shorewards. 



Not very far from this highest terrace a clear section was 

 open in a gravel-pit in which gravel was being dug out of a 

 terrace of the very same height, viz. about ten metres above 

 sea-Ievel. This gravel had a reddish brown colour and varied 

 in size from that of a pea up to that of a walnut, some pebbles 

 also attaining the size of a hen's egg. In this gravelly mass 

 some scattered remains of shells may be traced, such as
