   Specimens 
  examined. 
  

  

  This 
  species 
  was 
  uot 
  taken 
  in 
  1884, 
  but, 
  as 
  indicated 
  above, 
  a 
  large 
  

   male, 
  nearly 
  80 
  uim 
  in 
  length, 
  was 
  taken 
  in 
  1885. 
  

  

  It 
  is 
  at 
  once 
  distinguished 
  from 
  the 
  others 
  of 
  the 
  genus 
  by 
  the 
  very 
  

   short 
  lostrnm 
  (which, 
  though 
  considerably 
  longer, 
  strikingly 
  recalls 
  

   that 
  of 
  Hymenodora 
  glacialis), 
  and 
  the 
  very 
  large, 
  laterally 
  compressed.
