  Jay 
  assigned 
  Nuttall's 
  manuscript 
  name 
  to 
  C. 
  onyx 
  Sowerby 
  where 
  it 
  remains. 
  Carpenter, 
  

   however, 
  described 
  the 
  Nuttall 
  shell 
  from 
  "upper 
  California" 
  although 
  he 
  was 
  not 
  certain 
  

   that 
  its 
  difference 
  from 
  C. 
  onyx 
  merited 
  specific 
  rank. 
  He 
  thought 
  (1864b) 
  it 
  might 
  be 
  a 
  

   northern 
  "variety" 
  of 
  C. 
  onyx.
