  Remarks. 
  — 
  I 
  have 
  seen 
  only 
  two 
  specimens 
  of 
  this 
  form 
  from 
  the 
  

   Chalk 
  Rock. 
  The 
  species 
  was 
  founded 
  by 
  Goldfuss 
  on 
  a 
  cast 
  from 
  

   the 
  Quader 
  Sandstone 
  of 
  Schandau. 
  A 
  specimen 
  from 
  Touraine 
  

   was 
  described 
  by 
  Dujardin 
  as 
  P. 
  septemplicatus, 
  Nilsson, 
  but 
  it 
  was 
  

   shown 
  to 
  be 
  distinct 
  from 
  that 
  species 
  by 
  Romer, 
  who 
  changed 
  the 
  

   name 
  to 
  P. 
  Dujardini, 
  by 
  which 
  it 
  has 
  since 
  been 
  generally 
  known. 
  

   Geinitz's 
  P. 
  squamifer 
  and 
  Reuss's 
  P. 
  Dujardini 
  appear 
  to 
  be 
  

   distinct 
  from 
  this 
  species.
