  it 
  looks 
  very 
  much 
  as 
  if 
  the 
  taxonomists 
  

   themselves 
  are 
  the

  This 
  confusion

  hardly 
  clarified

   elaborate

  Although 
  Ortmann's 
  description 
  and 
  figure 
  are 
  not 
  all 
  that 
  could 
  

   be 
  desired, 
  there 
  seems 
  to 
  be 
  no 
  other 
  species 
  in 
  the 
  collection 
  that 
  

   agrees 
  as 
  well 
  with 
  his 
  description 
  as 
  do 
  these 
  specimens 
  and 
  they 
  

   are 
  therefore 
  referred 
  to 
  Nymphon 
  ja/ponicum. 
  This 
  is 
  a 
  large 
  hand- 
  

   some 
  species, 
  apparently 
  restricted 
  to 
  Japanese 
  waters 
  and 
  therefore 
  

   appropriately 
  named, 
  as 
  is 
  not 
  often 
  the 
  case 
  with
