  Since 
  the 
  first 
  part 
  of 
  this 
  paper 
  was 
  published 
  (May, 
  1896) 
  I 
  have 
  

   had 
  another 
  opportunity 
  of 
  visiting 
  North 
  Devon 
  and 
  West 
  Somer- 
  

   set, 
  the 
  former 
  district 
  as 
  one 
  of 
  the 
  Directors 
  of 
  the 
  Excursion 
  of 
  

   the 
  Geologists' 
  Association 
  in 
  July 
  1896, 
  and 
  the 
  latter 
  district 
  

   in 
  company 
  with 
  the 
  Rev. 
  G. 
  F. 
  Whidborne, 
  M.A., 
  F.G.S., 
  the 
  

   Rev. 
  H. 
  H. 
  Winwood, 
  M.A., 
  F.G.S., 
  Mr. 
  J. 
  G. 
  Hamling, 
  F.G.S., 
  

   Mr. 
  R. 
  S. 
  Herries, 
  M.A., 
  F.G.S., 
  and 
  Mr. 
  Upfield 
  Green, 
  F.G.S. 
  

   The 
  only 
  addition 
  to 
  the 
  fauna 
  in 
  North 
  Devon 
  was 
  the 
  dis- 
  

   covery 
  near 
  Barricane, 
  in 
  Morte 
  Bay, 
  of 
  a 
  portion 
  of 
  an 
  Orthoceras 
  

   (by 
  Dr. 
  Barrois, 
  F.M.G.S.) 
  ; 
  but 
  in 
  West 
  Somerset 
  some 
  forms 
  not 
  

   previously 
  known 
  to 
  occur 
  in 
  that 
  area 
  were 
  obtained. 
  

  

  The 
  faunas 
  so 
  far 
  discovered 
  in 
  West 
  Somerset 
  differ 
  very 
  

   markedly 
  from 
  those 
  found 
  in 
  the 
  Morte 
  Slates 
  in 
  North 
  Devon, 
  and 
  

   belong 
  to 
  higher 
  horizons 
  in 
  the 
  succession 
  ; 
  but 
  it 
  must 
  be 
  under- 
  

   stood 
  that 
  there 
  are 
  still 
  large 
  areas 
  which 
  have 
  been 
  but 
  imperfectly 
  

   explored. 
  In 
  so 
  great 
  a 
  thickness 
  also, 
  occupying 
  an 
  average 
  width 
  

   in 
  West 
  Somerset 
  of 
  from 
  5 
  to 
  6 
  miles, 
  it 
  is 
  only 
  natural 
  to 
  

   suppose 
  that 
  several 
  other 
  faunas 
  must 
  occur, 
  especially 
  as 
  in 
  

   the 
  faunas 
  already 
  described 
  there 
  appear 
  to 
  be 
  few, 
  if 
  any, 
  

   fossils 
  in 
  common. 
  As 
  many 
  parts 
  of 
  this 
  district 
  are 
  very 
  in- 
  

   accessible, 
  and 
  the 
  exposures 
  comparatively 
  few, 
  much 
  time 
  will 
  

   have 
  to 
  be 
  spent 
  before 
  anything 
  like 
  a 
  complete 
  examination 
  can 
  be 
  

   made. 
  The 
  evidence 
  so 
  far 
  obtained, 
  however, 
  is 
  so 
  important 
  in 
  its 
  

   bearing 
  on 
  the 
  succession 
  of 
  the 
  Devonian 
  rocks 
  in 
  North 
  Devon 
  

   and 
  West 
  Somerset 
  that 
  I 
  venture 
  to 
  submit 
  it 
  to 
  the 
  Society. 
  

  

  The 
  first 
  discovery 
  of 
  fossils 
  in 
  the 
  so-called 
  Morte 
  Slates 
  

   of 
  West 
  Somerset 
  was 
  made 
  in 
  the 
  spring 
  of 
  the 
  year 
  1895 
  by 
  

   Mr. 
  Whidborne, 
  Mrs. 
  Whidborne, 
  and 
  myself 
  in 
  the 
  slate-quarry
