  Remarks. 
  — 
  This 
  new 
  species 
  may 
  be 
  recognized 
  by 
  the 
  narrowness 
  

   of 
  the 
  three 
  white 
  bars, 
  especially 
  the 
  second 
  and 
  third, 
  and 
  by 
  the 
  

   black 
  caudal 
  fin 
  narrowly 
  edged 
  with 
  white 
  posteriorly. 
  It 
  is 
  sep- 
  

   arated 
  from 
  all 
  other 
  species 
  of 
  Amphriprion 
  by 
  the 
  key. 
  

  

  Named 
  tricinctus 
  in 
  reference 
  to 
  the 
  three
