  bj 
  the

  that 
  they

  It 
  was 
  moved 
  by 
  Dr.

  thanks 
  of 
  the 
  Academy. 
  After

  The 
  species 
  contained 
  in 
  this 
  and 
  the 
  succeeding 
  list, 
  were 
  collected 
  in 
  the 
  

   month 
  of 
  February, 
  1867, 
  by 
  Prof. 
  Gabb, 
  who 
  kindly 
  submitted 
  the 
  same 
  to 
  

   me 
  for 
  examination. 
  As 
  the 
  knowledge 
  of 
  Lower 
  California 
  Mollusca 
  is 
  

   exceedingly 
  limited, 
  the 
  publication 
  of 
  these 
  lists 
  may 
  be 
  of 
  some 
  benefit 
  to 
  

   students, 
  and 
  of 
  value 
  as 
  data 
  bearing 
  upon 
  geographical 
  distribution.

  this

  If 
  Mr. 
  Cuming's 
  " 
  habitat 
  " 
  is 
  

   correct, 
  it 
  shows 
  a 
  wide 
  range, 
  and 
  the 
  two 
  species 
  mentioned 
  herein 
  may 
  have 
  descended 
  

   from 
  the 
  same 
  ancestors.
