  Jones, 
  and 
  his 
  friend 
  Mr. 
  J. 
  Pickering 
  furnished 
  him 
  with 
  the 
  list. 
  

   Two 
  years 
  later 
  Mr. 
  S. 
  Y. 
  Wood 
  ennmerated 
  forty-five 
  species, 
  all 
  of 
  

   which 
  are 
  contained 
  in 
  the 
  previous 
  catalogue, 
  the 
  printer 
  perhaps 
  

   being 
  responsible 
  for 
  the 
  missing 
  species 
  ('Monogr. 
  Crag 
  Mollusca,' 
  

   vol. 
  ii. 
  pp. 
  304-310). 
  In 
  1883 
  one 
  of 
  us 
  pointed 
  out 
  that 
  the 
  

   single 
  example 
  of 
  Helix 
  aspersa 
  recorded 
  as 
  occurring 
  in 
  the 
  New- 
  

   bury 
  marl 
  was 
  probably 
  of 
  quite 
  recent 
  date, 
  since 
  the 
  numerous 
  

   pits 
  which 
  from 
  time 
  to 
  time 
  have 
  been 
  dug 
  in 
  the 
  peat 
  quickly 
  fill 
  

   up 
  (' 
  Science 
  Gossip,' 
  1883, 
  pp. 
  115, 
  237). 
  This 
  will 
  also 
  account 
  

   for 
  the 
  fact 
  that 
  Saxon 
  remains 
  have 
  been 
  found 
  at 
  a 
  depth 
  of 
  

   10 
  feet 
  in 
  the 
  peat. 
  All 
  efforts 
  to 
  trace 
  Mr. 
  Pickering's 
  collection 
  

   have 
  failed 
  ; 
  but 
  there 
  is 
  a 
  series 
  of 
  shells 
  from 
  these 
  and 
  other 
  

   Pleistocene 
  deposits 
  in 
  the 
  British 
  Museum 
  (Natural 
  History), 
  which 
  

   series 
  had 
  been 
  presented 
  by 
  him 
  to 
  the 
  Geologists' 
  Association, 
  1 
  

   and 
  transferred 
  by 
  that 
  body 
  to 
  the 
  National 
  Collection. 
  This 
  has 
  

   been 
  supplemented 
  from 
  a 
  series 
  in 
  our 
  own 
  possession. 
  

  

  From 
  these 
  sources 
  we 
  have 
  been 
  enabled 
  to 
  compile 
  a 
  list 
  of 
  

   forty-two 
  species, 
  seven 
  of 
  which 
  have 
  not 
  previously 
  been 
  recorded. 
  

   Besides 
  Helix 
  aspersa, 
  it 
  has 
  been 
  considered 
  advisable 
  to 
  reject 
  five 
  

   other 
  records 
  as 
  being 
  probable 
  errors 
  in 
  identification, 
  namely, 
  Limax 
  

   carinatus 
  i 
  = 
  Amalia 
  Sowerbyi, 
  Per.]; 
  Zonites 
  [=Vitrea~\ 
  alliaria 
  ; 
  

   Helix 
  hortensis, 
  an 
  error 
  for 
  H. 
  nemoralis 
  ; 
  Helix 
  \_—HeliceUa'] 
  vir- 
  

   gata, 
  and 
  Vertigo 
  alpestris. 
  Two 
  of 
  Mr. 
  Pickering's 
  species 
  are 
  

   now 
  considered 
  as 
  only 
  varieties 
  of 
  other 
  forms.
