  a 
  second 
  row 
  along 
  

   spiny 
  dorsal 
  fin, 
  mostly 
  covering 
  the 
  spines 
  except 
  tips, 
  then 
  the 
  row 
  

   of 
  scales 
  is 
  much 
  smaller 
  along 
  soft 
  rays, 
  almost 
  disappearing 
  on 
  base 
  

   of 
  last 
  ray; 
  anal 
  fin

  a 
  similar

  lateral

  again 
  2 
  scale 
  rows 
  below 
  on 
  caudal 
  peduncle; 
  

   fourth 
  pectoral 
  ray 
  usually 
  longest;

  Background 
  coloration 
  light 
  brownish 
  to 
  brownish, 
  

   with 
  a 
  brown-edged 
  white 
  bar 
  across 
  caudal 
  peduncle 
  just 
  behind 
  rear 
  

   of 
  bases 
  of 
  soft 
  dorsal 
  and 
  soft 
  anal 
  fins, 
  and 
  another 
  brown-edged 
  

   white 
  bar 
  just 
  behind 
  eye 
  from 
  side 
  of 
  head 
  to 
  nape; 
  3 
  prominent 
  black 
  

   ocellate 
  spots, 
  one 
  at 
  front 
  of 
  soft 
  dorsal, 
  another 
  at 
  front 
  of 
  soft 
  

   anal, 
  and 
  the 
  largest 
  occupying 
  each 
  pelvic 
  fin 
  and 
  the 
  underlying 
  

   part 
  of 
  the 
  body 
  opposite 
  the 
  pelvic 
  fins;

  white 
  bar 
  across 
  inter- 
  

   orbital 
  space; 
  middle

  barred. 
  The 
  two 
  smallest 
  

   specimens, 
  23 
  mm. 
  and 
  25 
  mm., 
  probably 
  represent 
  a 
  juvenile

  in 
  addition 
  to 
  the 
  white

  behind 
  the 
  ocellate 
  spots 
  there 
  

   is 
  another 
  white 
  bar

  front 
  of 
  them 
  that 
  extends 
  from 
  bases 
  of 
  last 
  

   dorsal 
  spines 
  to 
  bases 
  of 
  anal 
  spines; 
  another 
  white 
  band 
  extends 
  from 
  

   first 
  two 
  dorsal 
  spines 
  just 
  behind 
  pectoral 
  base 
  to 
  pelvics;

  Ecology. 
  — 
  This 
  mteresting 
  new 
  labrid 
  was 
  taken 
  only 
  at 
  depths 
  of 
  

   about 
  20 
  to 
  40 
  feet 
  in 
  the 
  lagoon 
  among 
  coral 
  heads. 
  It 
  was 
  not 
  seen 
  

   in 
  the 
  intertidal 
  zone 
  of 
  the 
  reefs. 
  

  

  Remarks.- 
  — 
  This 
  new 
  species 
  may 
  be 
  distinguished 
  from 
  species 
  in 
  

   the 
  genus 
  Wetmorella 
  by 
  means 
  of 
  the 
  key. 
  Its 
  closest 
  relative 
  is 
  

   philippina 
  philippina 
  from 
  which 
  it 
  differs 
  in 
  lacking 
  black 
  pigment 
  

   spots 
  in 
  the 
  caudal 
  fin; 
  ocellata 
  has 
  a 
  plain 
  dusky 
  caudal 
  fin 
  in 
  the 
  

   adult, 
  and 
  none 
  of 
  the 
  specimens 
  of 
  ocellata 
  has 
  even 
  a 
  trace 
  of 
  black 
  

   spots 
  in 
  the 
  caudal 
  fin. 
  After 
  studying 
  several 
  hundred 
  species 
  of 
  

   fishes 
  of 
  the 
  tropical 
  Indo-Pacific 
  in 
  numerous 
  families 
  we 
  place 
  a 
  

   great 
  deal 
  of 
  confidence 
  in 
  the 
  color 
  pattern 
  differences 
  such 
  as 
  occur 
  

   in 
  the 
  Chaetodontidae, 
  Labridae, 
  Serranidae, 
  and 
  other 
  families.
