  However, 
  if 
  Ball's 
  prior 
  remarks 
  have 
  precedent, 
  a 
  lectotype 
  should 
  be 
  selected. 
  Though 
  

   Ball 
  used 
  Carpenter's 
  manuscript 
  notes 
  for 
  the 
  major 
  details 
  of 
  his 
  paper 
  (1879), 
  he 
  probably 
  

   did 
  not 
  have 
  Carpenter's 
  type 
  of 
  the 
  species 
  in 
  his 
  study 
  of 
  the 
  dentition. 
  Carpenter's 
  type 
  

   remained 
  at 
  the 
  Redpath 
  Museum 
  where 
  it 
  is 
  novi^. 
  There 
  is 
  one 
  specimen 
  of 
  eight 
  separate 
  

   plates 
  labelled 
  by 
  Carpenter, 
  "original 
  type" 
  of 
  Maugerella 
  conspiciia 
  from 
  La 
  Paz 
  collected 
  

   by 
  Pease. 
  There 
  are 
  also 
  11 
  fine 
  complete 
  specimens 
  labelled 
  "type 
  normal 
  San 
  Biego 
  Hemp- 
  

   hill 
  Sta. 
  Barbara 
  Cooper 
  (= 
  magdalensis, 
  var. 
  stibobsolefa 
  B.A. 
  Rep.)." 
  Unfortunately 
  the 
  

   last 
  label 
  is 
  of 
  little 
  value 
  in 
  determining 
  a 
  specific 
  locality. 
  There 
  apparently 
  is 
  no 
  type 
  desig- 
  

   nated 
  by 
  Ball 
  in 
  existence, 
  so 
  that 
  the 
  Carpenter 
  specimen 
  is 
  the 
  logical 
  shell 
  to 
  become 
  the 
  

   lectotype 
  for 
  the 
  species 
  of 
  Ball's 
  authorship. 
  This 
  selection 
  would 
  automatically 
  change 
  the 
  

   type 
  locality 
  from 
  San 
  Biego 
  to 
  La 
  Paz. 
  

  

  Illustration 
  of 
  a 
  Carpenter 
  specimen 
  is 
  included 
  herein 
  for 
  completeness. 
  The 
  plates 
  of 
  

   the 
  specimen 
  are 
  pinkish 
  and 
  purplish 
  beneath 
  the 
  jugum. 
  

  

  Pilsbry 
  included 
  the 
  Carpenter 
  ms. 
  description 
  and 
  drawing 
  of 
  a 
  "variety 
  solidus" 
  (1892, 
  

   p. 
  64, 
  pi. 
  15, 
  fig.

  of 
  a 
  worn 
  specimen 
  which 
  he 
  regarded 
  only 
  as 
  an 
  individual 
  variation.

   Pilsbry,

  the 
  

  

  holotype 
  (1892).

  the

  statement 
  concerning 
  the 
  location 
  of

  in 
  Oldroyd 
  (p.
