  After 
  the 
  publication 
  of 
  Part 
  II., 
  1912, 
  Burnup 
  sent 
  another 
  specimen 
  

   of 
  the 
  shell 
  to 
  Ponsoub_y, 
  which 
  came 
  on 
  to 
  me 
  ; 
  it 
  bears 
  this 
  note 
  : 
  " 
  This 
  

   equals 
  my 
  No. 
  7 
  to 
  G.-A., 
  which 
  he 
  apparently 
  cousiders 
  is 
  amplintus

   It 
  is 
  a 
  finer 
  specimen, 
  and 
  I 
  give 
  its 
  dimensions 
  (second 
  example) 
  ; 
  it 
  is 
  

   rather 
  higher 
  in 
  the 
  spire 
  than 
  the 
  first 
  specimen 
  I 
  received
