  Remarks. 
  — 
  This 
  species 
  was 
  figured 
  by 
  J. 
  de 
  C. 
  Sowerby 
  as 
  

   Modiola 
  quadrata 
  ; 
  but 
  I 
  have 
  not 
  been 
  able 
  to 
  find 
  the 
  type, 
  

   which 
  was 
  stated 
  to 
  come 
  from 
  the 
  Lower 
  Chalk, 
  no 
  locality 
  being 
  

   mentioned. 
  The 
  figures 
  of 
  M. 
  Cottce 
  given 
  by 
  different 
  authors 
  

   vary 
  considerably, 
  but 
  a 
  careful 
  comparison 
  of 
  the 
  Chalk 
  Rock 
  

   specimens 
  with 
  the 
  figures 
  in 
  Geinitz 
  (' 
  Das 
  Elbthalgebirge 
  in 
  

   Sachsen 
  ') 
  and 
  Fritsch 
  leaves 
  practically 
  no 
  doubt 
  that 
  M. 
  quadrata 
  

   is 
  identical 
  with 
  M. 
  Cottce. 
  The 
  type 
  of 
  the 
  latter 
  comes 
  from 
  the 
  

   Cenomanian 
  of 
  Plauen, 
  near 
  Dresden. 
  In 
  England 
  the 
  species 
  is 
  

   not 
  common.

  Remarks. 
  — 
  In 
  the 
  present 
  paper 
  I 
  shall 
  refrain 
  from 
  giving 
  a 
  

   full 
  account 
  of 
  the 
  synonymy 
  and 
  distribution 
  of 
  the 
  species 
  of 
  

   Inoceramus 
  which 
  occur 
  in 
  the 
  Chalk 
  Rock, 
  as 
  I 
  hope 
  to 
  deal 
  at 
  

   another 
  time 
  with 
  all 
  the 
  species 
  of 
  this 
  genus. 
  The 
  specimen 
  

   figured 
  by 
  Mantell 
  is 
  different 
  from 
  Parkinson's 
  species, 
  and 
  is 
  

   probably 
  identical 
  with 
  Sowerby's 
  Brongniarti. 
  HantelPs 
  Bron- 
  

   gniarti 
  appears 
  to 
  be 
  the 
  same 
  as 
  Parkinson's. 
  Sowerby's 
  types 
  

   (without 
  locality) 
  are 
  preserved 
  in 
  the 
  British 
  Museum, 
  and 
  also 
  

   the 
  originals 
  of 
  Mantell's 
  2".

  from 
  near
