  "A 
  well-marked 
  variety 
  seems 
  to 
  have 
  an 
  admixture 
  of 
  black 
  blood, 
  probably 
  from 
  inter- 
  

   marriage 
  with 
  the 
  negro 
  race 
  of 
  A. 
  patina. 
  With 
  the 
  same 
  sculpture 
  externally, 
  the 
  interior 
  

   has 
  the 
  broad 
  black 
  margin 
  of 
  A. 
  patina, 
  (var. 
  scutum,') 
  and 
  a 
  dark 
  spot 
  in 
  the 
  centre. 
  One 
  

   specimen 
  is 
  dark 
  all 
  over. 
  Another 
  stout 
  dwarfed 
  shell 
  has 
  a 
  prettily 
  tesselated 
  border, 
  and 
  

   would 
  (in 
  a 
  mixed 
  collection) 
  he 
  taken 
  for 
  A. 
  cymbiohi.

  — 
  As 
  

   I 
  have 
  seen 
  no 
  intermediate 
  specimens 
  between 
  the 
  two 
  forms, 
  this 
  may 
  be 
  described 
  as 
  var. 
  

   Umatxila, 
  "A. 
  scahra,

  ;

  nigro, 
  seu 
  rarius 
  tessclato; 
  spectro 
  saepius 
  

   fusco

  "It 
  is 
  probably 
  the 
  Acmaca 
  patina 
  of 
  the 
  Mazatlan 
  Catalogue, 
  sp. 
  265, 
  but 
  the 
  specimens 
  

   were 
  too 
  much 
  worn 
  outside 
  to 
  decide 
  with 
  confidence."

  Pilsbry 
  (1891) 
  figured 
  "original" 
  specimens 
  of 
  this 
  species 
  from 
  Smithsonian 
  Institution 
  

   collections 
  as 
  stipulated 
  in 
  the 
  explanation 
  of 
  his 
  illustrations 
  (pi. 
  3). 
  The 
  specimens 
  of 
  

   Figures 
  45 
  and 
  46 
  he 
  stated 
  in 
  the 
  text 
  (p. 
  14) 
  to 
  be 
  from 
  San 
  Diego. 
  The 
  first 
  and 
  only 
  

   definite 
  reference 
  by 
  Carpenter 
  to 
  the 
  form 
  was 
  to 
  a 
  San 
  Diego 
  shell 
  (Carpenter, 
  1864, 
  p. 
  

   540). 
  Although 
  the 
  types 
  are 
  not 
  extant, 
  the 
  type 
  locality 
  is 
  San 
  Diego. 
  A 
  lectotype 
  might 
  

   well 
  be 
  selected 
  from 
  the 
  specimens 
  figured 
  by 
  Pilsbry.

  notes

  Marshall 
  on 
  type 
  

  

  This 
  nude 
  name 
  of 
  Carpenter 
  is 
  represented 
  by 
  4 
  syntypes 
  in 
  the 
  U. 
  S. 
  National 
  Museum, 
  

   no. 
  15490, 
  labelled 
  "Neeah 
  Bay 
  Swan." 
  If 
  Dall's 
  (1871) 
  brief 
  comparison, 
  using 
  Carpenter's 
  

   name, 
  with 
  A. 
  mitra 
  be 
  regarded 
  as 
  adequate 
  to 
  validate 
  the 
  name 
  of 
  a 
  form 
  of 
  subspecific 
  

   worth, 
  Dall 
  must 
  be 
  credited 
  as 
  the 
  author 
  and 
  not 
  Carpenter. 
  Dall's 
  comments 
  (1871, 
  p. 
  242) 
  

   were 
  as 
  follows 
  : 
  

  

  "The 
  striated 
  variety 
  (tenuisculpta, 
  Cpr.) 
  [of 
  ./. 
  niiira] 
  appears 
  very 
  distinct 
  from 
  the 
  

   smooth 
  form, 
  but 
  every 
  gradation 
  may 
  be 
  found 
  in 
  a 
  very 
  large 
  scries. 
  The 
  unique 
  type 
  of 
  

   Scurria 
  f 
  funiculata, 
  Cpr., 
  now 
  before 
  me, 
  differs 
  from 
  the 
  smallest 
  specimen 
  of 
  tenuisculpta, 
  

   only 
  in 
  having 
  the 
  riblets 
  even 
  more 
  prominent, 
  close, 
  and 
  rounded, 
  and 
  being 
  thinner 
  and 
  

   smaller. 
  . 
  . 
  ." 
  

  

  The 
  types 
  were 
  regarded 
  by 
  Dal! 
  and 
  Marshall 
  as 
  cc|uivalent 
  to 
  .-/. 
  funiculata.
