  that 
  the 
  following 
  new 
  species 
  has 
  not 
  been 
  described 
  appears 
  to 
  have 
  

   been 
  overlooked. 
  This 
  is 
  the 
  more 
  strange 
  considering 
  that 
  it 
  is 
  

   apparently 
  the 
  only 
  species 
  referable 
  to 
  the 
  genus 
  to 
  be 
  found 
  in 
  the 
  

   Atlantic 
  States 
  at*least 
  so 
  far 
  north.
