1898-1902. No. 33.] UPPER DEVONIAN FISH REMAINS. 49 



I. The grey and red, often conglomerate sandstone in the middle 

 part of the series with 



1. Psammosteus arcticus new sp. 



2. Psammosteus complicatus new sp. 



3. Great Coccosteomorph. 



4 Bothriolepis cf. hydrophila AG. 



5. Bothriolepis(?) sp. Large form. 



6. Holoptychius Scheii new sp. 



7. Holoptychius cf. tuberculatus NEWB. 



8. Glyptolepis cf. paucidens AG. 



9. Teeth with dendrodont structure, presumably belonging to the pre- 

 ceding Hotoptychiidae. 



10. Osteolepis sp. 



1 1 . Phtonia cf. cylindrica HALL. 



12. Badly preserved remains of plants. 



II. S. 0. Hakens grey sandstone on the east side of Goose Fiord, 

 probably still higher up in the series, with 



t. Bothriolepis (?) sp. large form. 

 2. Tooth with rhizodont structure. 



III. The dark schists of Galgeodden somewhat higher in the series, 

 with remains of plants and 



1. Bothriolepis cf. hydrophila AG. 



2. Glyptolepis cf. paucidens AG. 



These strata correspond to the dark schists of Bregnekktften, with 

 their wealth of plants. 



IV. The conglomerate layers of Bregnekleften, just above the 

 preceding, with remains of plants and one or two doubtfull fragments 

 of fishes. 



As we observe, the faunas in the higher horizons show almost no 

 new elements. The difference consists mainly in the circumstance that 

 only one or two of the numerous forms that are found in the lowest 

 and abundant strata are found in the upper. We cannot therefore 

 divide the sandstone series into several faunic zones on 

 the basis of the fauna. This impoverishment of fauna, however is 

 of interest, in that it gives us an indication of the biological changes 

 that have taken place in those regions.
