I feel very much inclined to believe that these fossils were collected 

 from a locality very near to the place where the phoca-iauna was ob- 

 tained, since they have been mixed into one collection. Should this be 

 correct, we have here an indication of relatively small thicknesses for the 

 lower part of the Devonian with highest Silurian if we regard the phoca- 

 fauna of Niagaran age or perhaps for a complete absence of several 

 horizons from a corresponding period. In the Goose Fjord region, 3 

 4000 feet of sediment, perhaps more, come between the base of the 

 Series B and the high Devonian.
