  Linné 
  was 
  the 
  first 
  who 
  used 
  tlie 
  name 
  »GraptoUthus» 
  — 
  

   in 
  his 
  >->Systema

  Ed.

  1735,

  From 
  the 
  list 
  he 
  gives, 
  it 
  can 
  be 
  in- 
  

   ferred 
  that 
  Linné 
  in 
  1735 
  by 
  this 
  name 
  only 
  meant 
  den- 
  

   dritic 
  incrustations 
  and 
  similar 
  forms. 
  By 
  referring 
  to 
  his 
  

   Museum 
  Tessinianum, 
  published 
  in 
  1753, 
  it 
  can 
  plainly 
  be 
  

   seen 
  (p. 
  104), 
  that 
  he 
  intended 
  also 
  at 
  that 
  date 
  to 
  designate 
  

   various 
  inorganic 
  formations, 
  as 
  dendrites 
  and 
  the 
  concentric 
  

   structure 
  of 
  flints. 
  He 
  gives 
  in 
  his 
  »Skånska 
  Eesa» 
  (Travels 
  

   in 
  Scania) 
  1751, 
  a 
  sketch, 
  which 
  evidently 
  represents 
  some 
  

   graptolites. 
  The 
  slab, 
  which 
  contained 
  these, 
  he 
  had 
  collected 
  

   from 
  a 
  hill 
  of 
  gravel, 
  named 
  »Bybjer», 
  close 
  to 
  the 
  church 
  at 
  

   O. 
  Herrestad. 
  From 
  the 
  figure 
  it 
  is 
  to 
  be 
  presumed, 
  thatthe 
  

   straight 
  form 
  represents 
  a 
  Climacograptus 
  ; 
  the 
  two 
  others 
  a 
  

   convoluted 
  Monograptus. 
  In 
  the 
  Geological 
  Museum 
  at 
  Lund 
  

   there 
  are 
  some 
  pieces 
  of 
  shale, 
  collected 
  by 
  Professor 
  Lund- 
  

   gren 
  from 
  the 
  exact 
  locality 
  at 
  Bybjer 
  ^). 
  Three 
  different 
  types 
  

   of 
  shales 
  are 
  represented: 
  1) 
  Graptolite-shale 
  v^rith 
  Pliyllo- 
  

   graj)tus 
  sp. 
  2) 
  Gray 
  Gala-shale 
  with 
  Mon. 
  priodon 
  Bronn 
  and 
  

   Mon. 
  lÄnnarssoni 
  Tullb. 
  mscr.; 
  and 
  3) 
  Brown 
  shale 
  of 
  Birkhill- 
  

   age, 
  with 
  Climacograptus 
  scalaris 
  L., 
  Monogr. 
  triangulatus 
  

   Harkn., 
  M. 
  gregarius 
  Lapw. 
  and 
  Diplograptiis 
  cfr 
  folium 
  His. 
  

  

  It 
  appears 
  exceedingly 
  probable, 
  that 
  the 
  Linnean 
  shale 
  

   was 
  of 
  the 
  last 
  mentioned 
  type. 
  The 
  fossils 
  thereupon 
  preser- 
  

   ved 
  would 
  thus 
  almost 
  certainly 
  have 
  been 
  the 
  Climacograptus 
  

   referred 
  to 
  above 
  and 
  Monograptus 
  triangulatus 
  Harkn., 
  that 
  

   is 
  to 
  say, 
  two 
  of 
  the 
  most 
  prominent 
  types. 
  

  

  ') 
  Professor 
  Luis^dg-rex 
  has 
  kindly 
  commnaicated 
  the 
  fact, 
  that 
  no 
  

   rocks 
  exist 
  here 
  in 
  situ. 
  Graptolite-slate 
  occurs 
  as 
  detached 
  blocks 
  in 
  

   the 
  mäss 
  of 
  gravel, 
  a 
  circumstance 
  which 
  is 
  also 
  evident 
  from 
  LlNNÉ'S 
  

   description.
