6,5 mm. Fine sand of a more light colour.

1 — Fine sand of a more light colour. 



0,5 — Clayey, fine sand of bluish-grey colour. 



2 — Fine sand of a more light colour.

V. 150 — Fine sand, rather well assorted, and of a reddish- 

 grey colour. This layer is somewhat irregularly 

 built up from alternating strata, but lamination 

 is of a monotome character. 

 150 — Fine sand and coarse gravel with stones of the 

 size of a nut to that of an egg. 



VI. Upon this deposit of sand and gravel we find a layer of fine 

 clay, a little mixed with sand, and of a yellowish-grey co- 

 lour, or in some places waved. The thickness of this clay- 

 layer somewhat varies betweeen two or three metres, or we 

 may assume a mean thickness of about two metres and a 

 half. The bordering plane between this clay-layer and the 

 underlying deposit of sand and gravel is very irregular indicat- 

 ing a disturbtion of the layers or rather a slip of clay that 

 at some remote time covered the lower grounds. This clay 

 proved to be fossil-bearing too, and the following species 

 were picked out of it: — 



Portlandia lenticula Moll. was not rare in casts of rather 

 normal type even if they do as a rule prove to be somewhat 

 small. Sometimes it belongs to a rather ovate type. 



Cardium edule Lin. was not rare, but, as a rule the speci- 

 mens were rather small. 



Axinus flexuosus Mont. forma typica was not rare indeed. 

 The specimens, however, had a relatively small size. 



Abra longicallis Sc. Numerous casts of forma typica oc- 

 curred, but, as a rule only relatively small.
