  to 
  repeat 
  them 
  here. 
  The 
  single 
  specimen 
  of 
  Helix 
  differs 
  

   from 
  those 
  previously 
  recorded, 
  which 
  were 
  dark 
  purple- 
  

   brown. 
  It 
  is 
  of 
  a 
  luteous 
  tint, 
  with 
  a 
  brown 
  zone 
  above 
  and 
  

   below 
  the 
  somewhat 
  acute 
  periphery 
  ; 
  the 
  penultimate 
  and 
  

   upper 
  whorls 
  are 
  also 
  dark 
  brown. 
  The 
  Bulimus 
  belongs 
  to 
  

   the 
  same 
  variety 
  which 
  is 
  described 
  in 
  my 
  second 
  Report. 
  

  

  Two 
  specimens 
  which 
  I 
  regard 
  as 
  a 
  variety 
  of 
  Helieina 
  

   fisciata 
  are 
  pale 
  at 
  the 
  apex, 
  the 
  rest 
  of 
  the 
  upper 
  surface 
  

   being 
  reddish 
  and 
  more 
  or 
  less 
  freckled 
  or 
  reticulated 
  with 
  

   white, 
  especially 
  the 
  last 
  whorl. 
  The 
  lower 
  surface 
  is 
  yel- 
  

   lowish 
  and 
  the 
  labrum 
  bright 
  yellow. 
  In 
  form 
  and 
  sculpture 
  

   they 
  are 
  normal. 
  

  

  The 
  three 
  examples 
  of 
  II. 
  platychila 
  are 
  unusually 
  small, 
  

   having 
  an 
  extreme 
  diameter 
  of 
  7 
  millimetres. 
  They 
  consist 
  

   of 
  five 
  whorls 
  as 
  usual, 
  are 
  uniformly 
  dirty 
  whitish, 
  in 
  other 
  

   respects 
  agreeing 
  with 
  ordinary 
  specimens. 
  

  

  The 
  collection 
  from 
  St. 
  Lucia 
  contains 
  only 
  six 
  species 
  f, 
  

   but 
  of 
  these 
  four 
  are 
  new. 
  This 
  is 
  not 
  altogether 
  surprising, 
  

   for, 
  so 
  far 
  as 
  I 
  can 
  ascertain, 
  the 
  conchological 
  fauna 
  of 
  the 
  

   island 
  has 
  only 
  been 
  very 
  casually 
  investigated. 
  

  

  Until 
  the 
  year 
  1869 
  only 
  two 
  species 
  had 
  been 
  recorded 
  

   from 
  this 
  locality 
  — 
  Helix 
  orbiculata 
  and 
  Bulimus 
  cudacostylus 
  

   — 
  the 
  latter 
  and 
  the 
  four 
  new 
  species 
  hereafter 
  described 
  baing, 
  

   so 
  far 
  as 
  known 
  at 
  present, 
  restricted 
  to 
  this 
  island. 
  Several 
  

   of 
  the 
  other 
  species 
  occur 
  also 
  on 
  one 
  or 
  more 
  of 
  the 
  adjacent 
  

   islands 
  or 
  even 
  on 
  the 
  mainland 
  of 
  South 
  America. 
  Mr. 
  

   Ralph 
  Tate 
  spent 
  about 
  two 
  hours 
  on 
  St. 
  Lucia 
  in 
  1869, 
  and 
  

   was 
  fortunate 
  in 
  collecting 
  as 
  many 
  as 
  twelve 
  species 
  ; 
  these 
  

   were 
  obtained 
  in 
  the 
  neighbourhood 
  of 
  Castries, 
  on 
  the 
  west 
  

   side 
  of 
  the 
  island. 
  Mr. 
  Ramage's 
  specimens 
  were 
  all 
  collected 
  

   at 
  " 
  Fonds 
  St. 
  Jacques," 
  the 
  precise 
  position 
  of 
  which 
  I 
  have 
  

   been 
  unable 
  to 
  discover. 
  

  

  As 
  in 
  previous 
  Reports, 
  I 
  have 
  appended 
  a 
  list 
  of 
  the 
  

   known 
  species, 
  with 
  references 
  to 
  some 
  of 
  the 
  more 
  important 
  

   figures 
  and 
  their 
  geographical 
  range.
