  This 
  species, 
  now 
  unknown, 
  is 
  compared 
  by 
  Haliday 
  

   to 
  imllidipes, 
  from 
  which 
  it 
  differs 
  chiefly 
  by 
  the 
  oral 
  

   aperture, 
  and 
  the 
  crenulate 
  furrow 
  of 
  the 
  mesopleurre. 
  

   Only 
  one 
  specimen 
  occurred, 
  the 
  locality 
  of 
  which 
  is 
  not 
  

   given.
