  A 
  species 
  of 
  moderate 
  size, 
  apparently 
  differing 
  only 
  from 
  

   Eugnathus 
  minor 
  in

  relatively 
  smaller, 
  more 
  numerous 
  mandi- 
  

   bular

  in 
  the 
  comparatively 
  deeper 
  abdominal 
  region 
  and 
  

   more 
  slender 
  caudal 
  pedicle. 
  

  

  This
