the environs of Mandal, Flekkefjord, etc. at the south-west 

 corner of Norway (pp. 536, 537; here is an interesting occur- 

 rence of tapes decussatus and mya arenaria nearly at the 

 present sea-level at Kadland, not far from Mandal). 



Gorresponding shell-occurrences are also known on the west 

 coast of Norway. 



On Jæderen (Ogne, p. 537); in the environs of Bergen {^^. 

 538—543; studied by H. Friele; interest attaches to the occur- 

 rence of several species — macoma tennis, odostomia pallida, 

 rissoa Sarsii, eulima intermedia, mangelia attenuata, cylichna 

 cylindracea — not hitherto [found in the postglacial banks of 

 the Kristiania region) ; in Lyster in Sogn (pp. 543 — 548 ; studied 

 by dr. H. H. Reusch); and in Ørlandet at the north-west cor- 

 ner of the Trondhjems Fjord (pp. 548—550; studied by M. Sårs). 



Pp. 550 — 556. 3. The Youngest Postglacial Clay; the Scro- 



bicularia Clay, 



Gorresponding with the just-mentioned lowest postglacial 

 shell-banks of the Kristiania region, representing the last phase 

 of the uplift, there is a series of clay-occurrences both from the 

 Kristiania Valley and from other parts of the Kristiania region, 

 always at very slight heights above the sea. 



In the Kristiania Valley, the leading fossil of this youngest 

 postglacial clay is scrohicularia piperata, from which form it 

 can be characterized as „the scrohicularia clay". 



The fauna of this clay has been specially studied in the 

 Kristiania Valley itself. The fauna, which is not rich, is given 

 in the table on p. 553. Gorresponding clay-beds are known in 

 other parts of the Kristiania region, and in Bohuslan, Sweden 

 (pp. 554—556), in Denmark, in the environs of Trondhjem, etc. 



Pp. 556 — 565. A Summary of the Youngest Postglacial 

 Mollusc Fauna of the Kristiania Region. 



The entire fauna of the lower tapes-banks and the isocardia 

 clay of the Kristiania region comprises, as far as is at present
