  Introduction. 
  

  

  The 
  organisms 
  found 
  in 
  the 
  "Wenlock 
  Shales 
  of 
  Shropshire 
  have 
  

   been 
  already 
  alluded 
  to 
  by 
  Mr. 
  Maw 
  and 
  by 
  Mr. 
  Davidson 
  in 
  their 
  

   joint 
  paper 
  in 
  the 
  ' 
  Geological 
  Magazine 
  ' 
  for 
  the 
  year 
  1881 
  *. 
  The 
  

   remarks 
  of 
  these 
  authors 
  bore 
  chiefly 
  upon 
  the 
  Brachiopoda 
  found 
  

   in 
  the 
  shales 
  ; 
  but 
  the 
  other 
  organisms 
  were 
  casually 
  alluded 
  to 
  in 
  

   passing. 
  Since 
  this 
  joint 
  paper 
  was 
  written, 
  I 
  have 
  had 
  an 
  oppor- 
  

   tunity 
  of 
  working 
  over 
  nearly 
  one 
  hundredweight 
  and 
  a 
  half 
  of 
  

   the 
  debris, 
  and 
  this, 
  in 
  all 
  probability, 
  may 
  represent 
  from 
  six 
  to 
  

   eight 
  tons 
  of 
  the 
  unwashed 
  clay. 
  My 
  object 
  in 
  searching 
  was 
  

   principally 
  to 
  pick 
  out 
  the 
  Polyzoa 
  and 
  the 
  smaller 
  Actinozoa 
  of 
  the 
  

   debris 
  ; 
  but 
  in 
  doing 
  this 
  I 
  felt 
  very 
  reluctant 
  to 
  pass 
  over 
  organisms 
  

   which 
  belonged 
  to 
  other 
  than 
  these 
  two 
  classes 
  ; 
  consequently, 
  to 
  

   some 
  extent, 
  my 
  collection 
  consists 
  of 
  specimens 
  illustrative 
  of 
  the 
  

   Actinozoa, 
  Echinodermata, 
  Annelida, 
  Crustacea, 
  and 
  Brachiopoda, 
  

   as 
  well 
  as 
  the 
  Polyzoa 
  of 
  the 
  shales. 
  It 
  is 
  not 
  my 
  intention 
  in 
  the 
  

   present 
  paper 
  to 
  commit 
  myself 
  to 
  remarks 
  on 
  the 
  genera 
  belonging 
  

   to 
  these 
  classes 
  otherwise 
  than 
  by 
  presenting 
  a 
  Table 
  of 
  the 
  whole 
  

   series 
  of 
  associated 
  fossils. 
  This 
  Table 
  is 
  divided 
  into 
  twelve 
  

   columns, 
  eleven 
  of 
  which 
  are 
  allotted 
  to 
  the 
  several 
  localities 
  from 
  

   which 
  Mr. 
  Maw 
  supplied 
  me 
  with 
  material; 
  the 
  other 
  column 
  

   affords 
  me 
  the 
  opportunity 
  of 
  completing 
  the 
  range 
  of 
  species 
  by 
  

   recording 
  their 
  presence 
  in 
  the 
  Wenlock 
  Limestone. 
  I 
  have 
  no 
  

   desire 
  to 
  speak 
  of 
  species 
  found 
  in 
  the 
  cabinets 
  or 
  collections 
  of 
  

   others. 
  Every 
  organism 
  against 
  which 
  a 
  mark 
  is 
  placed, 
  with 
  the 
  

   exception 
  of 
  those 
  from 
  the 
  Wenlock 
  Limestone, 
  has 
  been 
  found 
  in 
  

   the 
  shales 
  supplied 
  by 
  Mr. 
  Maw 
  ; 
  and 
  even 
  the 
  Brachiopoda 
  are 
  

   given, 
  not 
  from 
  the 
  lists 
  of 
  Messrs. 
  Maw 
  and 
  Davidson, 
  but 
  from 
  my 
  

   own 
  pickings 
  from 
  the 
  shale. 
  To 
  do 
  this 
  properly, 
  Mr. 
  Davidson 
  has 
  

   kindly 
  named 
  for 
  me 
  a 
  set 
  of 
  specimens 
  submitted 
  to 
  him 
  for 
  that 
  

   purpose, 
  and 
  to 
  these 
  I 
  have 
  since 
  been 
  able 
  to 
  add 
  a 
  few 
  others. 
  

  

  It 
  is 
  to 
  be 
  regretted 
  that 
  much 
  of 
  the 
  finer 
  material 
  has 
  been 
  

   lost 
  in 
  the 
  washing 
  : 
  but 
  in 
  every 
  case, 
  before 
  I 
  parted 
  with 
  the 
  

   picked 
  material, 
  I 
  sifted 
  the 
  refuse 
  through 
  coarse 
  net 
  and 
  also 
  fine 
  

   muslin 
  ; 
  and, 
  after 
  rewa.sb.ing, 
  I 
  was 
  thus 
  enabled 
  to 
  pick 
  out 
  and 
  

   mount 
  a 
  very 
  fine 
  series 
  of 
  Entomostraca. 
  My 
  types 
  of 
  these 
  have 
  

   been 
  kindly 
  examined 
  by 
  Prof. 
  Rupert 
  Jones, 
  and 
  upon 
  his 
  authority 
  

   I 
  am 
  able 
  to 
  say 
  that 
  several 
  of 
  the 
  specimens 
  are 
  either 
  new 
  species 
  

   or 
  new 
  varieties. 
  These 
  Entomostraca 
  are 
  in 
  a 
  fine 
  state 
  of 
  preser- 
  

   vation 
  as 
  regards 
  the 
  carapace, 
  and 
  they 
  will 
  enable 
  me, 
  in 
  working 
  

   * 
  January, 
  March, 
  and 
  April.
