  of 
  this

  "Mr. 
  A. 
  Adams 
  suggested 
  the 
  above 
  expressive 
  name 
  for 
  this 
  very 
  remarkable 
  and

   shell."

  It 
  is 
  not 
  expedient 
  nor 
  true 
  to 
  credit 
  this 
  species 
  wholly 
  to 
  Adams 
  as 
  is 
  commonly 
  done. 
  

   Adams 
  suggested 
  the 
  name, 
  but 
  Carpenter 
  executed 
  the 
  description. 
  Credit 
  to 
  Adams 
  alone 
  

   when 
  it 
  is 
  not 
  in 
  a 
  publication 
  by 
  that 
  author 
  may 
  be 
  confusing, 
  even 
  though 
  the 
  original 
  

   reference 
  is 
  given 
  in 
  Dall 
  (1921) 
  and 
  Oldroyd 
  (1924). 
  

  

  A 
  similar 
  case 
  is 
  that 
  of 
  Assiniinca 
  grayana 
  Fleming 
  (Leach 
  in 
  Fleming. 
  1828), 
  type 
  spe- 
  

   cies 
  of 
  Assiniinca 
  Fleming 
  (Leach 
  in 
  Fleming), 
  which 
  see. 
  Leach 
  sent 
  Fleming 
  a 
  specimen 
  so 
  

   labelled 
  which 
  Fleming 
  acknowledged 
  in 
  his 
  description 
  of 
  the 
  new 
  species, 
  new 
  genus. 
  Thus 
  

   Leach 
  would 
  be 
  the 
  author 
  of 
  Assiniinca. 
  However, 
  Fleming 
  is 
  rightfully 
  stipulated 
  in 
  litera- 
  

   ture 
  as 
  the 
  author.
