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

 from a locality very near to the place where the phoca-i&una 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 pJioca- 

 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.
