  A 
  copy 
  of 
  Carpenter's 
  description 
  (1864) 
  and 
  Pilsbry's 
  translation 
  was 
  published 
  by 
  

   Oldroyd. 
  To 
  complete 
  Oldroyd's 
  copy 
  the 
  following 
  should 
  be 
  added: 
  "On 
  the 
  confines 
  of 
  

   the 
  genus, 
  related 
  to 
  Cylichna." 
  [Carpenter, 
  1864a, 
  p. 
  314] 
  

  

  The 
  type 
  material 
  consists 
  of 
  two 
  specimens 
  in 
  the 
  U. 
  S. 
  National 
  Museum. 
  They 
  are 
  on 
  

   Carpenter's 
  original 
  glass 
  mount, 
  with 
  label 
  "type. 
  C.S.L." 
  The 
  two 
  specimens, 
  9 
  mm. 
  in 
  

   height, 
  and 
  2 
  mm. 
  in 
  height, 
  respectively, 
  possibly 
  represent 
  the 
  young 
  and 
  adult 
  of 
  the 
  same 
  

   species. 
  The 
  larger 
  specimen 
  is 
  of 
  the 
  approximate 
  dimension 
  given 
  by 
  Carpenter, 
  and 
  the 
  

   writer 
  therefore 
  selects 
  it 
  as 
  the 
  lectotype. 
  If 
  the 
  smaller 
  specimen 
  is 
  not 
  a 
  juvenile, 
  it 
  is 
  of 
  

   a 
  different 
  species 
  but 
  of 
  the 
  same 
  genus 
  and 
  subgenus. 
  

  

  The 
  present 
  illustration 
  is 
  the 
  first 
  published 
  of 
  the 
  series. 
  The 
  fine 
  concentric 
  striations 
  

   which 
  cover 
  the 
  surface, 
  greater 
  anteriorly 
  and 
  posteriorly, 
  do 
  not 
  show 
  in 
  the 
  photograph. 
  

  

  Tiie 
  species 
  was 
  described 
  from 
  Cape 
  San 
  Lucas 
  and 
  is 
  included 
  in 
  this 
  report 
  because 
  a 
  

   statement 
  of 
  its 
  distribution 
  has 
  been 
  extended 
  by 
  Dall 
  to 
  Catalina 
  Island.
