three metres. This deposit may of course have been laid down 

 during different geological stages as is also indicated by the 

 character of the fauna. But, the scarcity of fossils did not admit, 

 any accurate distinction betvveen the different subordinate layers 

 of this rather complicate series. We should, however, be justified 

 in looking out for deep-water representatives of the Romerik 

 glacial stage, the MytUus-st&ge and the Portlandia-st&ge in this 

 faunistic series characterized by the occurrence of the following 

 species: — 



Nucula tenuis Mont. 



Portlandia lenticula Moll. forma typica of Iength 6 mm. 

 This species was very numerous and often occurred in complete 

 specimens; sometimes representatives may even be seen of a 

 quadrifasciate or ovate type. 



Area glacialis Gray. This species was rather numerous 

 too, ranging from forma typica through intermediate types to 

 var. raridentata, or even var. pectunculoides. As instances of 

 index a couple of measurements is added: — 



Length 14 mm. Height 10 mm. Index 0,714 

 — 11 „ 9 „ - 0,818 



Sometimes complete specimens may be found. 



Area pedunculoides Sc. forma typica. 



Abra tongicallis Sc. 



Antalis striolata Stimps. forma typica 



Siphonodentalium vitreum Sårs var. striata 



Lunatia groenlandica Beck forma typica. 



Protuta borealis Sårs forma typica. This species was 

 rather numerous. 



Placostegus politus Sårs. 



VI. Immediately and directly overlying the just above de- 

 scribed rather complicate or even complex deposit is a layer of 

 fine, bluish-grey clay of the thickness of about three metres. 

 This layer might most easily be designated as a deposit of 

 Mytilus-c\a,y. But this classification would only form a rather 

 slight base for stratigraphical recognition. The deposit in ques-
