﻿SILTTEIAN 
  ROCKS 
  OF

  In 
  Scania, 
  on 
  the 
  other 
  hand, 
  there 
  are 
  several 
  formations 
  above 
  

   the 
  Betiolites-beds. 
  

  

  The 
  Cardiola 
  intermpta-heHs 
  have 
  precisely 
  the 
  same 
  characters 
  

   and 
  fauna 
  as 
  the 
  Coldwell 
  beds 
  of 
  the 
  Lake- 
  district, 
  and 
  occur 
  in 
  

   the 
  same 
  relative 
  position. 
  

  

  The 
  grey 
  gritty 
  beds 
  of 
  Bjersjolagard 
  are 
  probably 
  on 
  the 
  horizon 
  of 
  

   the 
  Coniston 
  grits, 
  and 
  perhaps 
  also 
  of 
  the 
  lower 
  portion 
  of 
  the 
  

   Bannisdale 
  slates. 
  Dr. 
  Tullberg 
  correlates 
  these 
  and 
  the 
  underlying 
  

   Cardiola-beds 
  with 
  the 
  Lower 
  Ludlow 
  ; 
  but 
  they 
  are 
  in 
  the 
  position 
  

   of, 
  and 
  have 
  the 
  same 
  fauna 
  as, 
  true 
  Wenlock 
  beds. 
  

  

  The 
  green 
  shales 
  and 
  yellow 
  sandstones 
  of 
  Bjersjolagard 
  and 
  the 
  

   red 
  sandstones 
  of 
  Bamstsa, 
  on 
  the 
  other 
  hand, 
  have 
  a 
  true 
  Ludlow 
  

   fauna. 
  

  

  I 
  have 
  already 
  stated 
  that 
  the 
  highest 
  beds 
  of 
  lEalmo, 
  near 
  

   Christiania, 
  with 
  Pterinea 
  retroflexa 
  &c, 
  are 
  really 
  \Venlock.

  the 
  summary 
  of 
  the 
  correlation 
  of 
  the 
  

   principal

  Scandinavia, 
  Bohemia,

  Migrations 
  of 
  the 
  Faunas. 
  

   The 
  migrations 
  of 
  the 
  Swedish 
  faunas 
  may 
  be 
  studied 
  in 
  two 
  ways 
  : 
  

   — 
  first, 
  by 
  noticing 
  the 
  occurrence, 
  in 
  two 
  beds 
  of 
  different 
  age, 
  of
