  These 
  notes 
  are 
  based 
  on 
  two 
  collections. 
  First, 
  a 
  collection 
  made 
  

   by 
  the 
  author 
  at 
  Woods 
  Holl, 
  Massachusetts, 
  in 
  July 
  and 
  Au<4ust, 
  1889; 
  

   and 
  second, 
  a 
  collection 
  belonging 
  to 
  the 
  United 
  States 
  National 
  

   ^Museum. 
  

  

  It 
  is 
  a 
  matter 
  of 
  regret 
  on 
  the 
  part 
  of 
  the 
  author 
  that 
  fuller 
  accounts 
  

   of 
  some 
  of 
  the 
  species 
  described 
  are 
  not 
  given 
  ; 
  particularly 
  is 
  this 
  true 
  

   of 
  new 
  species, 
  and 
  of 
  those 
  concerning 
  whose 
  identification 
  there 
  is 
  

   some 
  doubt. 
  The 
  excuse, 
  in 
  nearly 
  every 
  case, 
  is, 
  either 
  the 
  small 
  

   amount 
  or 
  unsatisfactory 
  condition 
  of 
  the 
  material.
