   The 
  bibliography 
  of 
  this 
  very 
  interesting 
  group 
  of 
  animal 
  remains 
  

   is 
  comparatively 
  scanty 
  if 
  compared 
  with 
  the 
  literature 
  of 
  some 
  

   other 
  groups. 
  In 
  his 
  celebrated 
  ' 
  Petrefacten 
  ' 
  (1820) 
  Schlo- 
  

   theim 
  founded 
  the 
  genus 
  Gomulites 
  for 
  the 
  inclusion 
  of 
  " 
  certain 
  

   Silurian 
  fossils 
  of 
  somewhat 
  doubtful 
  affinities, 
  but 
  apparently 
  most 
  

   nearly 
  allied 
  to 
  the 
  tubicolar 
  annelids 
  "*. 
  In 
  the 
  ' 
  Silurian 
  System,'" 
  

   published 
  in 
  1839, 
  species 
  found 
  in 
  the 
  Upper 
  and 
  Lower 
  Silurian 
  

   were 
  identified 
  with 
  species 
  described 
  by 
  Schlotheim 
  : 
  and 
  since 
  

   then 
  authors 
  have 
  referred 
  specimens 
  to 
  either 
  Tent 
  acuities 
  or 
  

   Gomulites. 
  In 
  ' 
  Siluria,' 
  and 
  also 
  in 
  the 
  -Cambridge 
  Catalogue," 
  

   Salter 
  rectified 
  somewhat 
  the 
  earlier 
  errors 
  by 
  showing 
  that 
  some 
  

   at 
  least 
  of 
  the 
  casts 
  of 
  specimens 
  had 
  been 
  referred 
  to 
  as 
  separate 
  

   species. 
  In 
  his 
  ' 
  British 
  Palaeozoic 
  Fossils 
  ' 
  M-'Coy 
  redefines 
  and 
  

   limits 
  the 
  species 
  of 
  previous 
  authors 
  ; 
  but 
  he 
  adds 
  little 
  to 
  our 
  

   knowledge 
  of 
  the 
  group 
  generally. 
  It 
  is 
  to 
  Prof. 
  Nicholson, 
  whilst 
  

   working 
  amongst 
  the 
  American 
  Paheozoic 
  fauna, 
  that 
  we 
  owe 
  the 
  

   most 
  detailed 
  account 
  of 
  Tubicolar 
  Annelida, 
  and 
  that 
  from 
  mate- 
  

   rial 
  collected 
  by 
  himself. 
  In 
  working 
  over 
  the 
  species 
  which 
  had 
  

   previously 
  been 
  identified 
  as 
  Tentacidites 
  he 
  first 
  saw 
  the 
  necessity 
  

   of 
  founding 
  new 
  genera 
  for 
  their 
  reception. 
  Tentacidites 
  f 
  was 
  re- 
  

   defined 
  and 
  limited, 
  and 
  Prof. 
  Nicholson 
  separated 
  this 
  group 
  from 
  

   ordinary 
  Tubicolar 
  Annelida 
  ; 
  but 
  I 
  am 
  not 
  prepared 
  to 
  say 
  that 
  

   Tentacidites 
  belongs 
  to 
  the 
  Pteropoda. 
  Following, 
  however, 
  the 
  

   example 
  set 
  by 
  Nicholson, 
  I 
  shall 
  keep 
  them 
  separate, 
  and 
  deal 
  

   with 
  their 
  structural 
  peculiarities 
  further 
  on. 
  The 
  new 
  genera 
  

   founded 
  by 
  Nicholson 
  are 
  Conchicolites 
  and 
  Ortonia.

  a

  the

  of 
  the 
  Clinton 
  group 
  

   of 
  rocks 
  possessing 
  characters 
  altogether 
  different 
  from 
  Gornvlites, 
  

   and 
  more 
  like 
  Gonchicolites 
  of 
  Nicholson.
