  Remarks. 
  — 
  This 
  species 
  is 
  easily 
  distinguished 
  by 
  its 
  combination 
  

   of 
  very 
  small 
  tarsus 
  and 
  propodus 
  and 
  the 
  large 
  chelae 
  with 
  their 
  

   slender 
  straight 
  fingers. 
  The 
  locality 
  at 
  which 
  this 
  species 
  was 
  col- 
  

   lected 
  is 
  southwest 
  of 
  Sagami 
  Bay. 
  As 
  already 
  remarked 
  above, 
  this 
  

   seems 
  to 
  be 
  the 
  species 
  identified 
  by 
  Ohshima 
  and 
  Kishida 
  as 
  N. 
  

   japonicum.
