  The 
  holotype 
  (specimen 
  marked* 
  by 
  Carpenter) 
  has 
  denticulations 
  on 
  the 
  interior 
  of 
  

   the 
  labrum, 
  as 
  will 
  readily 
  be 
  seen. 
  Those 
  on 
  the 
  labrum 
  of 
  the 
  "paratype" 
  are 
  less 
  pro- 
  

   nounced 
  but 
  visible. 
  The 
  angle 
  of 
  spire, 
  particularly 
  the 
  right 
  side, 
  of 
  the 
  "paratype" 
  is 
  

   greater 
  than 
  that 
  of 
  the 
  holotype, 
  the 
  body 
  whorl 
  is 
  broader, 
  and 
  the 
  character 
  of 
  the 
  

   plications 
  on 
  the 
  inner 
  lip 
  is 
  different. 
  The 
  "paratype" 
  does 
  not 
  belong 
  to 
  the 
  same 
  species 
  

   and 
  should 
  be 
  separated. 
  It 
  is 
  recorded 
  here 
  only 
  as 
  original 
  reference 
  (PI.

  the

  incorrect.

  "Hab. 
  Santa 
  Barbara, 
  Post-Pliocene. 
  Of 
  this 
  extremely 
  elegant 
  species, 
  two 
  specimens 
  

   were 
  found 
  by 
  Mr. 
  Gabb, 
  of 
  which 
  one 
  is 
  very 
  perfect. 
  It 
  greatly 
  resembles 
  C. 
  modesta 
  from 
  

   Neeah 
  Bay, 
  but 
  is 
  much 
  more 
  slender. 
  The 
  nucleus 
  is 
  chrysodermoid, 
  very 
  slanting, 
  with 
  

   sunken 
  spire."

  The 
  specimens 
  by 
  which 
  Grant 
  and 
  Gale 
  and 
  Burch 
  illustrated 
  A. 
  modesta 
  are 
  not 
  of 
  

   typical 
  A. 
  modesta. 
  Both 
  pictures 
  seem 
  to 
  represent 
  the 
  same 
  group 
  as 
  that 
  of 
  the 
  individual 
  

   figured 
  by 
  Arnold 
  as 
  A. 
  gracilior. 
  Grant 
  and 
  Gale 
  described 
  theirs 
  as 
  possibly 
  A. 
  gracilior 
  

   of 
  Carpenter 
  but 
  not 
  of 
  Arnold.
