  VINE 
  ON 
  THE 
  ANNELIDA 
  TTJBICOLA 
  

  

  and 
  amplen'tis 
  from 
  the 
  railway-cutting 
  opposite 
  Swan 
  Iron 
  Bridge. 
  

   Mr. 
  Smith 
  also 
  procured 
  specimens 
  of 
  Tentaculites, 
  Conchicolites 
  and 
  

   Qornulites 
  described 
  in 
  this 
  paper. 
  

  

  There 
  is. 
  however, 
  additional 
  interest 
  in 
  the 
  discovery 
  of 
  the 
  

   arenaceous 
  Annelid 
  of 
  the 
  Silurian 
  Shales. 
  When 
  sending 
  his 
  slide 
  

   to 
  me, 
  Mr. 
  John 
  Young 
  said 
  : 
  — 
  '•' 
  An 
  almost 
  identical 
  form 
  is 
  found 
  

   in 
  the 
  washings 
  of 
  the 
  Hairmyres 
  Shales 
  from 
  the 
  Carboniferous 
  

   formation 
  of 
  Scotland. 
  At 
  Hairmyres 
  I 
  have 
  found 
  it 
  in 
  somewhat 
  

   larger 
  fragments, 
  and 
  adherent 
  to 
  the 
  stems 
  of 
  Crinoids 
  and 
  fronds 
  

   of 
  Fenestella 
  — 
  which 
  shows 
  that 
  this 
  Annelid 
  was 
  not 
  a 
  free 
  form, 
  

  

  but 
  attached 
  itself 
  to 
  other 
  bodies 
  The 
  Carboniferous 
  species 
  

  

  I 
  have 
  not 
  yet 
  met 
  with 
  in 
  any 
  other 
  locality 
  than 
  the 
  one 
  given 
  "*. 
  

  

  This 
  completes 
  my 
  list 
  of 
  Tubicolar 
  Annelida 
  found 
  in 
  the 
  shale- 
  

   washings. 
  Throughout 
  the 
  whole 
  of 
  the 
  series 
  I 
  have 
  not 
  found 
  

   any 
  specimens 
  which 
  may 
  undoubtedly 
  be 
  placed 
  with 
  the 
  Annelida 
  

   Polychaeta 
  of 
  Dr. 
  G. 
  Jennings 
  Hinde. 
  I 
  have 
  found 
  one 
  specimen 
  

   of 
  a 
  small 
  jaw 
  very 
  much 
  like 
  the 
  outline 
  of 
  the 
  Much-Wenloek 
  

   (Enonites 
  aspersus 
  of 
  that 
  author. 
  It 
  is 
  serrated 
  like 
  that 
  species, 
  

   only 
  with 
  a 
  less 
  number 
  of 
  teeth 
  : 
  but 
  the 
  hook-like 
  termination 
  is 
  

   also 
  serrated 
  with 
  three 
  teeth, 
  and 
  under 
  the 
  teeth 
  of 
  the 
  longest 
  

   part 
  of 
  the 
  jaw 
  there 
  are 
  circular 
  places. 
  The 
  specimen 
  is 
  about 
  a 
  

   line 
  and 
  a 
  half 
  in 
  length. 
  It 
  is 
  from 
  the 
  shales 
  over 
  the 
  Wenlock 
  

   Limestone, 
  no. 
  46. 
  

  

  Ln 
  the 
  figures 
  of 
  sections 
  I 
  have 
  endeavoured 
  more 
  particularly 
  

   to 
  show 
  the 
  structural 
  character 
  of 
  the 
  tubes 
  in 
  the 
  types 
  of 
  

   Gomulites 
  and 
  Tentaculites. 
  These 
  are 
  so 
  different 
  that 
  they 
  must 
  

   strike 
  the 
  eye 
  at 
  once 
  ; 
  but 
  my 
  main 
  object 
  is 
  to 
  form 
  a 
  basis 
  of 
  

   future 
  comparison 
  for 
  the 
  more 
  detailed 
  study 
  of 
  the 
  leading 
  types 
  

   of 
  the 
  Tubicolar 
  Annelida.
