Although of these forms only a few are of importance for conclusions 

 as to age, it may be said with certainty that the fauna must be consi- 

 dered as contemporary with those described from the Keyser member of 

 the Helderberg group of Maryland, from the Decker Fe rry-Rond out- 

 Ma n 1 i u s of New Jersey, and the Cobbleskill-Rondout-Manlius of 

 eastern New York. The stratigraphical position of series B is thus to be 

 sought in the very transition zones between Silurian and Devonian. As 

 a whole the fauna cited above may be said to have more of a Silurian 

 than of a Devonian aspect. 



Above Series B comes Series C, a sequence of marly shales passing 

 upwards into arenaceous deposits. The thickness, as measured in 

 Gaasefjord, is about 300 m. No fossils have been found here. 



Still higher comes the richly fossiliferous series D, consisting of 

 500 m. of shales and limestones, near the top of sandstones. Series D 

 was by SCHEI divided into subdivisions Da Di. Of the fossils collected 

 by him the two most dominant groups, the brachiopods and the corals 

 have been studied in detail, the former by OSCAR ERICH MEYER, who 

 has published the results of his work in a paper ,,Die devonischen 

 Brachiopoden von Ellesmereland" (this report No. 29, 1913), the corals 

 by STEPHAN LOEWE, who has written a paper entitled n Die devonischen 

 Korallen von Ellesmereland" (this report No. 30, 1913). 



In the following are cited the list of fossils given in the two papers.
