  Of 
  this 
  volume, 
  entitled 
  " 
  An 
  Introduction 
  to 
  the 
  Study 
  of 
  the 
  

   Genera 
  of 
  the 
  Palaeozoic 
  Brachiopoda," 
  Part 
  I 
  was 
  issued 
  in 
  1892, 
  

   and 
  some 
  account 
  of 
  its 
  contents 
  was 
  given 
  in 
  the 
  report 
  for 
  that 
  

   year. 
  Part 
  II 
  has 
  not 
  yet 
  been 
  issued 
  in 
  its 
  completed 
  form. 
  On 
  

   account 
  of 
  interruption 
  in 
  the 
  printing 
  of 
  the 
  lithographic 
  plates, 
  

   it 
  became 
  evident 
  early 
  in 
  the 
  year 
  that 
  the 
  publication 
  of 
  this 
  

   second 
  volume 
  would 
  be 
  seriously 
  delayed, 
  if 
  the 
  text 
  were 
  to 
  be 
  

   held 
  back 
  until 
  the 
  plates 
  were 
  completed. 
  As 
  the 
  printing 
  of 
  

   the 
  text 
  was 
  progressing 
  as 
  rapidly 
  as 
  consonant 
  with 
  the 
  charac- 
  

   ter 
  of 
  the 
  work, 
  it 
  was 
  deemed 
  advisable 
  to 
  issue 
  it 
  in 
  the 
  form 
  

   of 
  fascicles 
  whenever 
  the 
  completion 
  of 
  any 
  large 
  group 
  of 
  

   generic 
  discussions 
  justified 
  it. 
  Accordingly, 
  in 
  July, 
  1893, 
  Part 
  

   II, 
  Fascicle 
  I 
  was 
  issued 
  and 
  distributed 
  to 
  scientific 
  societies 
  and 
  

   workers 
  in 
  Palaeontology. 
  This 
  fascicle 
  covered 
  pages 
  1-176, 
  

   with 
  155 
  cuts, 
  and 
  embraced 
  all 
  palaeozoic 
  genera 
  of 
  the 
  spire- 
  

   bearing 
  brachiopods. 
  Following 
  is 
  the 
  table 
  of 
  its 
  contents, 
  in 
  

   which 
  the 
  generic 
  names 
  in 
  italics 
  are 
  those 
  here 
  regarded 
  as 
  

   irretrievable 
  synonyms.
