  The 
  holotype 
  of 
  this 
  species 
  is 
  preserved 
  in 
  the 
  U. 
  S. 
  National 
  Museum 
  and 
  not, 
  as 
  

   stated 
  by 
  Oldroyd 
  and 
  followed 
  by 
  Grant 
  and 
  Gale, 
  in 
  the 
  British 
  Museum. 
  

  

  The 
  holotype 
  bears 
  the 
  label 
  '"Type 
  Monterey 
  Taylor," 
  which 
  coincides 
  with 
  the 
  

   original 
  description. 
  A 
  growth 
  over 
  the 
  apical 
  whorls 
  obscures 
  the 
  characters, 
  but 
  the 
  body 
  

   whorl 
  is 
  well 
  preserved. 
  The 
  sculpture 
  is 
  not 
  worn, 
  and 
  the 
  microscopic 
  longitudinal 
  stria- 
  

   tions 
  are 
  clearly 
  seen. 
  At 
  the 
  crossing 
  of 
  the 
  longitudinal 
  and 
  spiral 
  ribs 
  sharp 
  nodes 
  are 
  

   formed. 
  

  

  Mitromorpha 
  gracilior 
  Hemphill 
  in 
  Tryon, 
  1884, 
  p. 
  317, 
  pi. 
  25, 
  fig. 
  62 
  was 
  described 
  by 
  

   Tryon 
  as 
  a 
  "variety" 
  of 
  M. 
  aspera 
  (Carpenter). 
  Tryon 
  used 
  a 
  manuscript 
  name 
  of 
  Hemp- 
  

   hill 
  and 
  did 
  not 
  indicate 
  a 
  locality 
  for 
  the 
  specimen 
  which 
  he 
  figured. 
  Grant 
  and 
  Gale 
  (1931, 
  

   p. 
  597) 
  followed 
  by 
  Smith 
  and 
  Gordon 
  (1948, 
  p. 
  185) 
  indicated 
  Monterey 
  as 
  the 
  type 
  

   locality. 
  There 
  is 
  nothing 
  in 
  Tryon 
  to 
  confirm 
  that 
  statement 
  of 
  tyi)e 
  locality. 
  

  

  Three 
  specimens 
  in 
  the 
  Redpath 
  Museum 
  (no. 
  2360) 
  are 
  labelled 
  "Mitromorpha 
  gracilior 
  

   Hemphill 
  type 
  S. 
  Diego." 
  These 
  specimens 
  were 
  the 
  types 
  of 
  the 
  Hemphill 
  manuscript 
  name, 
  

   but 
  since 
  Tryon 
  is 
  the 
  author 
  of 
  the 
  specific 
  name, 
  the 
  specimen 
  which 
  Tryon 
  figured 
  would 
  

   be 
  the 
  holotype. 
  Unfortunately 
  it 
  had 
  no 
  published 
  locality. 
  The 
  Redpath 
  Museum 
  specimens 
  

   have 
  lost 
  their 
  status 
  as 
  syntypes. 
  M. 
  gracilior 
  is 
  now 
  regarded 
  as 
  distinct 
  from 
  M. 
  aspera; 
  

   hence 
  the 
  tracing 
  of 
  a 
  type 
  locality 
  in 
  connection 
  with 
  the 
  holotype 
  has 
  not 
  been 
  pursued 
  in 
  

   this 
  report.

  Tryon 
  gave 
  an 
  English 
  translation 
  of 
  Carpenter's 
  description 
  above. 
  Carpenter's 
  measure- 
  

   ments 
  in 
  mm. 
  would 
  be 
  slightly 
  larger 
  than 
  those 
  given 
  by 
  Tryon. 
  

  

  The 
  type 
  has 
  not 
  been 
  found. 
  Dall 
  (1913) 
  apparently 
  had 
  not 
  seen 
  the 
  shell 
  but 
  took 
  

   his 
  cue 
  from 
  the 
  above 
  description 
  (1865a) 
  that 
  the 
  single 
  broken 
  specimen 
  was 
  unidenti- 
  

   fiable. 
  

  

  Keen 
  {in 
  Burch, 
  1946,

  62, 
  p. 
  10) 
  suggested 
  that 
  if 
  O 
  phiodermella 
  incisa 
  Carpenter 
  was 
  

   preoccupied 
  (secondary 
  homonym), 
  [? 
  Daphnella^ 
  effusa 
  Carpenter 
  was 
  available. 
  This 
  

   would 
  indicate 
  that 
  the 
  two 
  forms 
  were 
  regarded 
  as 
  conspecific.
