1898-1902. No. 32.] FOSSIL FAUNAS FROM SERIES B. 45 



to these views the age of Series G may fall into the Coeymuns (possibly 

 also the New Scotland) or thereabouts. 



A question that would be of interest to solve would be whether any 

 of the faunas quoted from the earlier investigations on fossils brought 

 home by Expeditions from the Arctic archipelago represent the same hori- 

 zon as Series B of Ellesmereland. The difficulty here is that most of the 

 existing lists are so old that they really do not give much information. 

 Besides we very often find that, fossils from different horizons are mixed. 

 A revision of the identifications of the older collections would be of 

 great importance for our knowledge of the stratigraphy and palaeo- 

 geography of the Arctic regions. As far as I have seen nowhere else 

 in the Arctic has a fauna been found that shows so much resemblance 

 to the one considered in this paper that I should dare to correlate them. 

 The fauna collected hy Dr. HAYES on the west shore of Kennedy Chan- 

 nel, containing the following forms according to identifications made by 

 MEEK 1 : Zaphrentis Haysii MEEK, Syringopora, Favosites, Stropho- 

 mena rhouiboidalis, Strophodonta Headleyana HALL(?), Stroph. Becki 

 HALL(?), Rhynclwnella sp., Coelospira concava HALL, Spirifer perla- 

 mellosus HALL, Loxonema(?) Kanei MEEK, Orthoceras sp., Illcenus, is 

 - as MEEK emphasizes - - of Lower Helderberg age but it is without 

 doubt younger than the faunas of Series B. After the list quoted it 

 must be correlated with New Scotland and Becraft and therefore corre- 

 sponds probably with the lower part of SCHEI'S Series D. 



A fauna very often met with in the list of Arctic fossils, the de- 

 tailed stratigraphical horizon of which cannot yet be said to be known, 

 is what may be termed the Lissatrypa phoca-launa. The form which 

 goes under the names Rhynchonella or Atrypa phoca SALTER has been 

 quoted from a great number of Arctic localities mostly together with 

 certain corals. It was mentioned by SALTER 2 , HAUGHTON ETHERIDGE, 

 AMI, LAMBE and LEE from in all the following places : Gape Riley, Gorn- 

 wallis Isl., Leopold Is!., Griffith's Isl., Seal Isl., Beechey Isl., Gamier Bay, 

 W. and E side of Boothia Felix, Ferry Point, Dobbin Bay, Bessels Bay, 

 shores of Prince Regent Inlet and possibly others. 



The L. pftoca-fauna is generally mentioned only as Silurian, in the 

 newer reports of the Canadian paleontologists it is placed at near the 

 Niagaran, yet as almost all the forms are unknown outside the Arctic 3
