  "The 
  shells 
  above 
  described 
  constitute 
  what 
  might 
  be 
  called 
  a 
  Darwinian 
  group 
  of 
  specific 
  

   forms. 
  With 
  the 
  exception 
  of 
  the 
  typical 
  shells 
  dredged 
  by 
  Dr. 
  Kennerley, 
  they 
  are 
  all 
  in 
  

   very 
  bad 
  condition. 
  The 
  Pugetian 
  specimens 
  are 
  flattened, 
  with 
  open 
  umbilicus, 
  as 
  might 
  be 
  

   expected 
  from 
  quiet 
  water. 
  Two 
  specimens, 
  however, 
  form 
  an 
  exact 
  transition 
  to 
  the 
  Xeeah 
  

   Bay 
  shells, 
  of 
  which 
  a 
  fair 
  number 
  (var. 
  a) 
  were 
  sent 
  by 
  Mr. 
  Swan, 
  though 
  worn 
  and 
  

   generally 
  decorticated. 
  They 
  are 
  more 
  elevated, 
  with 
  fainter 
  sculpture 
  ; 
  and 
  pass, 
  by 
  insensible 
  

   gradations, 
  into 
  AI. 
  tenusculpta, 
  the 
  two 
  principal 
  spiral 
  lines 
  becoming 
  evanescent, 
  and 
  a 
  

   few 
  others 
  intercalating. 
  In 
  this 
  state 
  (var. 
  |3) 
  the 
  species 
  can 
  only 
  be 
  separated 
  by 
  the 
  

   operculum, 
  which 
  is 
  pale 
  and 
  thin, 
  and 
  destitute 
  of 
  the 
  strongly 
  expressed 
  rib 
  of 
  the 
  'Vahlii' 
  

   group. 
  A 
  third 
  form 
  (var. 
  y) 
  would 
  certainly 
  claim 
  specific 
  rank, 
  but 
  for 
  the 
  intermediate 
  

   series 
  of 
  a 
  and 
  (3. 
  The 
  diagnostic 
  characters 
  for 
  the 
  whole 
  series 
  are 
  the 
  smooth 
  operculum, 
  

   the 
  eight 
  narrow 
  riblets 
  round 
  the 
  base, 
  with 
  angular 
  umbilicus 
  and 
  the 
  sharp, 
  narrow, 
  prin- 
  

   cipal 
  riblets 
  above, 
  witli 
  wide 
  interspaces, 
  smooth 
  except 
  from 
  the 
  lines 
  of 
  growth, 
  which 
  are 
  

   principally 
  visible 
  in 
  the 
  epidermis. 
  There 
  may 
  be 
  three 
  (so-called) 
  species 
  in 
  the 
  group, 
  viz.: 
  

   lirulata, 
  subelevata 
  and 
  conica." 
  [Carpenter, 
  1865e, 
  p. 
  61] 
  

  

  There 
  are 
  three 
  specimens 
  in 
  the 
  U. 
  S. 
  National 
  Museum 
  labelled 
  "type 
  Puget 
  Sd. 
  Dr. 
  

   Kennerley." 
  This 
  label 
  coincides 
  with 
  Carpenter's 
  description. 
  The 
  middle-sized 
  specimen 
  of 
  

   the 
  three 
  is 
  figured 
  herein.
