  Family 
  CORIXID/E. 
  

  

  These 
  are 
  the 
  water-boatmen 
  which 
  inhabit 
  almost 
  every 
  clean 
  pond, 
  

   permanent 
  pool 
  or 
  sluggish 
  stream. 
  They 
  are 
  somewhat 
  flattened 
  above, 
  

   have 
  a 
  broad 
  short 
  head 
  and 
  an 
  exceedingly 
  hot 
  tongue. 
  The 
  species 
  

   are 
  predatory 
  in 
  habit, 
  closely 
  allied 
  and 
  not 
  well 
  determined 
  in 
  collec- 
  

   tions. 
  Practically 
  all 
  that 
  can 
  be 
  done 
  under 
  the 
  circumstances 
  is 
  to 
  

   give 
  a 
  list 
  of 
  those 
  species 
  that 
  are 
  so 
  distributed 
  that 
  their 
  occurrence 
  

   in 
  New 
  Jersey 
  is 
  a 
  reasonable 
  certainty, 
  adding 
  the 
  localities 
  for 
  such 
  

   as 
  have 
  been 
  determined 
  with 
  reasonable 
  certainty.
