  The 
  vegetation 
  of 
  Connecticut 
  

  

  grow 
  best 
  in 
  strongly 
  saline 
  waters 
  bordering 
  the 
  open 
  ocean, 
  and 
  

   in 
  Long 
  Island 
  Sound 
  they 
  develop 
  much 
  more 
  luxuriantly 
  east- 
  

   ward, 
  toward 
  the 
  entrance, 
  than 
  westward, 
  toward 
  the 
  head 
  of 
  

   the 
  Sound. 
  In 
  general, 
  there 
  is 
  little 
  question 
  that 
  the 
  algal 
  

   vegetation 
  of 
  the 
  lower 
  sublittoral 
  is 
  much 
  more 
  poorly 
  developed 
  

   along 
  the 
  Connecticut 
  shore 
  than, 
  for 
  example, 
  in 
  the 
  Woods 
  

   Hole 
  region. 
  A 
  list 
  of 
  species 
  characteristic 
  of 
  the 
  lower 
  sublittoral 
  

   in 
  this 
  region 
  Is 
  given 
  below, 
  but 
  while 
  all 
  of 
  these 
  are 
  known 
  to 
  

   be 
  more 
  or 
  less 
  abundant 
  in 
  Long 
  Island 
  Sound, 
  sufficient 
  data 
  

   are 
  not 
  available 
  to 
  permit 
  generalizations 
  regarding 
  their 
  relative 
  

   frequency.*
