  sides 
  of 
  which 
  the 
  outline 
  is 
  convex 
  : 
  dingy 
  or 
  brownish 
  white 
  ; 
  

   with 
  an

   riphery 
  ; 
  with

  white 
  : 
  indistinctly

  ; 
  with 
  fine 
  

   irregular 
  striae 
  of 
  growth 
  : 
  spire 
  convex, 
  moderately 
  elevated 
  : 
  

   whorls 
  nearly 
  five, 
  concave 
  in 
  the 
  lower 
  part, 
  in 
  the

  are 
  joined 
  together 
  at 
  base, 
  and 
  all 
  of 
  which 
  

   have 
  corresponding 
  external 
  furrows 
  : 
  umbilicus 
  deep,

  Helix 
  ing-ens, 
  var. 
  imperforata, 
  without 
  an 
  apparent 
  um- 
  

   bilicus, 
  is 
  more

  Another 
  

   variety, 
  indigna, 
  is 
  of 
  much 
  less 
  size, 
  and 
  is 
  much 
  less 
  acute 
  

   at 
  the 
  periphery. 
  It 
  is 
  also 
  imperforate. 
  

   ^ 
  Helix 
  consanguinea. 
  Shell 
  depressed,

  than 
  below 
  : 
  very

  but 
  strongly 
  granulated

  spire 
  

   regularly 
  convex 
  : 
  whorls 
  rather 
  more 
  than 
  four 
  and 
  one-half, 
  

   moderately 
  convex, 
  a 
  little 
  depressed 
  at 
  the

  side 
  next 
  

   the 
  suture 
  ; 
  last 
  whorl 
  with 
  a 
  narrow 
  not 
  very 
  prominent 
  

   keel 
  on 
  the 
  periphery 
  : 
  aperture

  labrum 
  well

  with 
  four 
  teeth

  which 
  three 
  

   have 
  corresponding 
  deep
