  Of^IVA. 
  In 
  searching 
  for 
  species 
  of 
  this 
  genus, 
  I 
  had 
  

   but 
  little 
  success, 
  although 
  all 
  the 
  sands 
  near 
  Panama 
  were 
  

   visited, 
  from 
  the 
  low 
  water 
  mark 
  of 
  the 
  spring 
  tides 
  upwards. 
  

   Of 
  the 
  ten 
  species 
  which 
  were 
  obtained, 
  only 
  one 
  was 
  found 
  

   alive. 
  Probably 
  the 
  species 
  appear 
  chiefly 
  at 
  certain 
  seasons. 
  

   The 
  one 
  which 
  was 
  found 
  alive 
  in 
  countless 
  myriads, 
  was 
  seen 
  

   during 
  only 
  a 
  part 
  of 
  my 
  stay 
  in 
  Panama.
