  of 
  either 
  animal, 
  or

   but 
  most 
  puzzling 
  of 
  the 
  small 
  shells 
  of 
  California. 
  It 
  has 
  relations 
  with

  The 
  type 
  material 
  consists 
  of 
  five 
  specimens 
  in 
  the 
  U. 
  S. 
  National 
  Museum 
  with 
  a 
  label, 
  

   "San 
  Diego 
  Cooper" 
  in 
  writing. 
  A 
  printed 
  label 
  of 
  "San 
  Pedro" 
  is 
  included. 
  Thus 
  one 
  can- 
  

   not 
  segregate 
  the 
  specimens 
  by 
  exact 
  locality. 
  

  

  The 
  chief 
  characteristic 
  of 
  sculpture 
  is 
  the 
  presence 
  of 
  the 
  regular 
  microscopic 
  spiral 
  

   striations 
  over 
  the 
  whole 
  surface. 
  Such 
  striations 
  are 
  on 
  the 
  young 
  shells 
  as 
  well 
  as 
  on 
  

   adults. 
  The 
  immature 
  shells 
  are 
  less 
  slender, 
  and 
  the 
  spire 
  is 
  not 
  so 
  elevated 
  as 
  on 
  the 
  

   older 
  specimens. 
  A 
  short 
  and 
  stubby 
  young 
  individual 
  has 
  plications 
  on 
  the 
  interior 
  of 
  the 
  

   labrum 
  similar 
  to 
  those 
  on 
  the 
  adult. 
  The 
  apex 
  of 
  the 
  shells 
  is 
  minute 
  and 
  sharp. 
  There 
  is 
  a 
  

   band 
  just 
  below 
  the 
  suture; 
  some 
  have 
  brown 
  spots 
  in 
  their 
  coloration.
