  Descriptions 
  of 
  New 
  Species 
  and 
  Varieties 
  of 
  Shells, 
  

  

  having 
  less 
  depth 
  and 
  a 
  greater 
  width 
  than 
  in 
  H. 
  paUiata 
  and 
  

   H. 
  Brovmii. 
  Except 
  in 
  its 
  greater 
  size, 
  it 
  very 
  closely 
  re- 
  

   sembles 
  the 
  former 
  species, 
  which 
  however 
  wants 
  the 
  spiral 
  

   lines 
  of 
  long 
  hairs 
  in 
  the 
  epidermis. 
  The 
  operculum 
  of 
  this 
  

   species 
  is 
  much 
  smoother. 
  I 
  adopt 
  the 
  name 
  suggested 
  by 
  Mr. 
  

   Chitty. 
  

  

  A 
  variety 
  of 
  Helicina 
  palliata 
  occurs, 
  in 
  which 
  the 
  lip 
  

   is 
  excessively 
  thickened 
  both 
  externally 
  and 
  internally, 
  con- 
  

   tracting 
  the 
  aperture. 
  It 
  may 
  be 
  designated 
  by 
  the 
  name 
  of 
  

   LABiosA. 
  It 
  is 
  a 
  local 
  variety.* 
  

  

  A 
  variety 
  of 
  Helicina 
  maxima 
  is 
  remarkable 
  for 
  its 
  pale 
  

   lemon 
  yellow 
  color 
  ; 
  it 
  may 
  be 
  designated 
  by 
  the 
  name 
  of 
  

   ciTRiNA. 
  The 
  usual 
  color 
  of 
  this 
  species, 
  under 
  the 
  epidermis, 
  

   is 
  the 
  same 
  as 
  that 
  of 
  H. 
  nobilis, 
  (see 
  above,) 
  with 
  less 
  of 
  

   white. 
  

  

  A 
  variety 
  of 
  Helicina 
  ampliata 
  in 
  the 
  collection 
  of 
  Mr. 
  

   Chitty 
  is 
  of 
  a 
  greenish 
  yellow 
  color, 
  with 
  a 
  broad 
  spiral 
  band 
  

   nearly 
  covering 
  the 
  upper 
  whorls, 
  where 
  it 
  is 
  dark 
  reddish 
  

   brown, 
  occupying 
  the 
  lower 
  part 
  of 
  the 
  middle 
  whorls 
  where 
  

   it 
  is 
  of 
  a 
  brownish 
  slate 
  color, 
  and 
  gradually 
  becoming 
  paler, 
  

   and 
  at 
  length 
  on 
  the 
  last 
  whorl 
  of 
  a 
  red 
  color. 
  

  

  Helicina 
  consanguinea. 
  Shell 
  subglobose, 
  moderately 
  

   thick 
  : 
  dark 
  brownish 
  red, 
  with 
  the 
  lip 
  white 
  ; 
  with 
  a 
  some- 
  

   what 
  hirsute 
  epidermis, 
  having 
  the 
  projecting 
  points 
  spirally 
  

   arranged 
  : 
  with 
  the 
  striae 
  of 
  growth 
  quite 
  distinct 
  : 
  apex 
  ob- 
  

   tuse 
  : 
  spire 
  with 
  the 
  outlines 
  much 
  curved 
  : 
  whorls 
  five, 
  mod- 
  

   erately 
  convex, 
  with 
  a 
  well 
  impressed 
  suture 
  : 
  aperture 
  semi- 
  

   orbicular 
  ; 
  lip 
  sinuous 
  above, 
  moderately 
  thickened 
  and 
  sharp, 
  

   but 
  well 
  reflected 
  except 
  at 
  the 
  extremities 
  ; 
  with 
  the 
  slit 
  

   broad 
  and 
  shallow.

  Dr. 
  Holland 
  remarks, 
  " 
  The 
  H. 
  palliata 
  found 
  about 
  here 
  [Bethany, 
  Man- 
  

   chester] 
  never 
  has 
  such 
  a 
  thickened 
  lip 
  : 
  [the 
  same 
  is 
  true 
  at 
  Marlboro, 
  Mandiester 
  

   C.' 
  B. 
  A.] 
  : 
  but 
  all 
  the 
  specimens 
  from 
  Maidstone 
  (our 
  station 
  on 
  the 
  mountain 
  oppo 
  

   site 
  to 
  Bethany) 
  are 
  of 
  this 
  description."
