  Avellana 
  pulchella 
  approaches 
  very 
  near 
  to 
  Avellana 
  alpina, 
  

   Pict. 
  et 
  Boux, 
  but 
  does 
  not 
  possess 
  such 
  a 
  long 
  spire, 
  and 
  dif- 
  

   fers 
  from 
  it 
  in 
  ornamentation 
  or 
  sculpture 
  ; 
  inasmuch 
  as 
  that 
  of 
  

   A. 
  alpina 
  is 
  composed 
  of 
  slightly 
  elevated 
  ridges 
  with 
  little 
  square 
  

   punctures, 
  whereas 
  in 
  A, 
  pulchella 
  the 
  ridges 
  are 
  not 
  raised 
  but 
  

   simply 
  marked 
  with 
  small 
  ovate 
  punctures. 
  

  

  It 
  will 
  be 
  seen 
  from 
  the 
  above 
  note 
  that 
  this 
  shell 
  diners 
  essenti- 
  

   ally 
  from 
  any 
  of 
  the 
  figured 
  species 
  of 
  Avellana, 
  although 
  possessing 
  

   certain 
  affinities, 
  inasmuch 
  as 
  the 
  size, 
  ornamentation, 
  the 
  thick 
  

   reflected 
  outer 
  lip, 
  the 
  denticulation 
  on
