  sea 
  level 
  was 
  about 
  42 
  fathoms 
  lower 
  at 
  that 
  time. 
  This 
  would 
  

   have 
  narrowed 
  the 
  channels 
  somewhat, 
  and 
  made 
  Cay 
  Sal 
  Bank 
  

   wholly 
  emergent 
  and 
  a 
  much 
  better 
  stepping 
  stone 
  for 
  a 
  Fundulus 
  

   migrating 
  from 
  Florida 
  to 
  Cuba. 
  

  

  Whether 
  a 
  Fundulus 
  exists 
  in 
  Cay 
  Sal 
  Bank 
  I 
  cannot 
  say. 
  To 
  my 
  

   knowledge 
  that 
  area 
  has 
  never 
  been 
  thoroughly 
  explored 
  ichthyolo- 
  

   gically. 
  There 
  are 
  some 
  small 
  keys 
  and 
  islets 
  such 
  as 
  Elbow, 
  Dog, 
  

   Damas, 
  Salt, 
  and 
  others 
  bordering 
  the 
  Bank, 
  the 
  average 
  depth 
  of 
  

   which 
  is 
  about 
  4 
  fathoms. 
  If 
  Fundulus 
  actually 
  migrated 
  to 
  Cuba 
  

   via 
  Cay 
  Sal 
  Bank 
  there 
  is 
  no 
  reason 
  why 
  a 
  fish 
  of 
  this 
  genus 
  should 
  

   not 
  occur 
  there. 
  

  

  Although 
  Fundulus 
  grandis 
  saguanu^ 
  is 
  as 
  yet 
  knawn 
  only 
  from 
  

   the 
  type 
  locality 
  it 
  will 
  probably 
  be 
  found 
  to 
  occur 
  throughout 
  the 
  

   continuous 
  shallow 
  bank 
  extending 
  along 
  the 
  coast 
  of 
  north-central 
  

   Cuba, 
  from 
  the 
  Hicacos 
  Peninsula 
  in 
  the 
  Province 
  of 
  Matanzas,

  of 
  Camagiiey.
