  N.E. 
  of 
  Edge-Hill 
  Station. 
  — 
  A 
  portion 
  of 
  these 
  were 
  obtained 
  by 
  

   me 
  out 
  of 
  the 
  brickfields 
  ; 
  the 
  remainder 
  from 
  the 
  railway-cutting 
  

   just 
  above. 
  Level 
  about 
  175 
  feet 
  above 
  ordnance 
  datum. 
  The 
  

   clay 
  is 
  similar 
  in 
  constitution 
  to 
  that 
  of 
  all 
  the 
  preceding 
  brick- 
  

   fields.

  Warrington. 
  — 
  These 
  shells 
  were 
  found 
  by 
  Mr. 
  Pears, 
  and 
  are 
  now 
  

   in 
  the 
  Warrington 
  Museum. 
  They 
  are 
  described 
  by 
  Mr. 
  Paterson 
  

   as 
  occurring 
  in 
  a 
  sand-seam 
  on 
  the 
  Liverpool 
  Extension 
  Railway 
  

   between 
  Bewsey 
  and 
  Sankey. 
  I 
  have 
  myself 
  examined 
  the 
  section, 
  

   which 
  consists 
  of 
  stratified 
  beds 
  of 
  sand, 
  -included 
  in 
  the 
  Boulder- 
  

   clay. 
  I 
  am 
  indebted 
  to 
  Mr. 
  Darbishire 
  for 
  the 
  correction 
  of 
  the 
  list, 
  

   the 
  one 
  published 
  by 
  Mr. 
  Paterson 
  being 
  incorrect 
  ; 
  he 
  informs 
  me 
  

   that 
  the 
  condition 
  of 
  the 
  shells 
  bears 
  a 
  striking 
  resemblance 
  to 
  those 
  of 
  

   the 
  Blackpool 
  Middle 
  sands.

  Gas-works, 
  Linacre. 
  — 
  About 
  50 
  feet 
  above

  D. 
  These 
  were 
  ob- 
  

   tained 
  by 
  Mr. 
  Isaac 
  Roberts, 
  F.G.S., 
  during 
  the 
  excavations 
  for 
  the 
  

   gas-holders 
  ; 
  all 
  of 
  them 
  appear 
  to 
  have 
  been 
  taken 
  from 
  the 
  clay 
  

   (see

  of 
  the 
  Liverpool 
  Geological 
  Society, 
  1870-1, 
  pp. 
  68, 
  

   69). 
  The 
  individuals 
  were 
  more 
  perfect 
  than 
  most 
  of 
  those 
  found 
  

   by 
  me. 
  

  

  Various 
  other 
  Localities 
  about 
  Liverpool. 
  — 
  These 
  were 
  found 
  by 
  Mr. 
  

   G. 
  H. 
  Morton, 
  F.G.S., 
  and 
  others, 
  and 
  are 
  given 
  by 
  him 
  in

  Pro- 
  

   ceedings 
  of 
  the 
  Liverpool 
  Geological 
  Society,

  &

  The 
  last 
  column 
  represents 
  shells 
  of 
  the 
  list, 
  which 
  are 
  to 
  be 
  found 
  

   now 
  on 
  the 
  Southport 
  or 
  Formby 
  shores. 
  I 
  am 
  indebted 
  to 
  Mr. 
  Chas. 
  

   Brown, 
  of 
  Southport, 
  who 
  thoroughly 
  worked 
  out 
  the 
  conchology 
  of 
  

   the 
  district, 
  for 
  these 
  particulars. 
  Those 
  marked 
  a 
  were 
  found 
  by 
  

   him 
  alive. 
  

  

  Note.
