and fishes. The state of i)reservation is often surprisingly good, espe- 

 ciall}' in the lower gray green layer, which is slightly cupriferous. 

 According to a preliminary analysis kindly made for me b}' Stud. Min. 

 Andrk.SEN, they contain about o. i;"/,, — ^0.23 "/o of copper. 



This rich upper horizon with l'hi/llocarids, Earyptervis and fishes 

 I have named the fish horizon. The fossils are specially abundant 

 in the lower, grey-green band. The fcjliowing forms are found: 



Dictyocfiris sp. V^ery common. 



2. Ceraiioairia sp. Not often in good specimens. 



3. Eurypterus Norvégiens nov. sp. Very common. 



4. Eurypterus minidns nov. sp. Rare. 



5. Eurypterus sp. Rare. 



6. Pterygotus sp. Rare in fragment. 



7. Acerasins robitstus nov. gen. & sp. A new cephalaspidomorph fish. 

 Very common. 



8. Micraspis gracilis nov. gen. & sp. A new cephalaspidomorph fish. 

 Not common. 



9. Pterolepis nitidus nov. gen. & sp. A new anaspid fish. Very 

 common. 



10. Pharyngolepis ohlongus nov. gen. & sp, A new anaspid fish. Not 

 common. 



11. lihyiwhoUpis parvulus nov. gen. &: sp. A new anaspid fish. Common. 



7. Reddish calcareous sandstone, often rich in shaly spots, in 

 thick beds, ca. 3 m. 



8. Redbrown shale with thinner and thicker slabs of redbrown 

 calcareous sandstone, often with beautiful ripplemarks, 3 — 4 m. In the 

 lower beds I found a poor fragment of Eurypterus sp., higher up there 

 are thin slabs very rich in trails of a Eurypterid, Merostomichnites sp. 

 This is the upper horizon with trails. 



Higher up the series is not so well exposed; but trails are also 

 found here. 



In this section then, there are the following horizons with fossils 

 and trails: 



I. The lower horizon with trails, about 3 m. up. 

 II. The lower horizon with P/iyllocarids and Eurypterids or 

 the Didyocaris -horizon, about 5.5 m . up.
