  — 
  Head 
  and 
  body 
  tan 
  to 
  dark 
  brown 
  on 
  upper 
  half 
  

   of 
  body, 
  lighter 
  below; 
  smaller 
  specimens 
  lighter 
  tan 
  than 
  larger 
  

   specimens; 
  a 
  dark 
  brown 
  stripe 
  extends 
  from 
  snout 
  through 
  eye 
  to 
  

   area 
  just 
  above 
  midbase 
  of 
  caudal 
  fin, 
  being 
  below 
  the 
  lateral 
  line 
  

   on 
  anterior 
  part 
  of 
  body 
  and 
  above 
  lateral 
  line 
  on 
  posterior 
  portion; 
  

   width 
  of 
  lateral 
  stripe 
  about 
  three-fourths 
  diameter 
  of 
  eye; 
  lateral 
  

   stripe 
  most 
  pronounced 
  in 
  adults 
  and 
  more 
  conspicuous 
  than 
  illus- 
  

   trated 
  by 
  Fowler 
  (1933) 
  or 
  Herre 
  and 
  Montalban 
  (1928); 
  body 
  with 
  

   three 
  dark 
  brown 
  saddles, 
  their 
  width 
  about 
  1 
  to 
  2 
  times 
  greater 
  than 
  

   diameter 
  of 
  eye; 
  first 
  saddle 
  passes 
  tln-ough 
  midbase 
  of 
  spinous 
  dorsal 
  

   fin, 
  the 
  second 
  through 
  midbase 
  of 
  soft 
  dorsal, 
  and 
  the 
  third 
  passes 
  

   over 
  caudal 
  peduncle 
  just 
  posterior 
  to 
  soft 
  dorsal 
  fin; 
  saddles 
  extend 
  

   ventrally 
  to 
  the 
  lateral 
  line 
  and 
  are 
  more 
  conspicuous 
  in 
  smaller 
  

   specimens; 
  the 
  two 
  anteriormost 
  saddles 
  almost 
  completely 
  faded 
  in 
  

   the 
  larger 
  specimens. 
  

  

  Spinous 
  dorsal 
  dusky 
  on 
  upper 
  half, 
  three 
  very 
  faint, 
  transverse, 
  

   dusky 
  bars 
  in 
  specimens 
  about 
  50 
  mm. 
  in 
  length; 
  soft 
  dorsal 
  with 
  2 
  

   faint, 
  dusky, 
  transverse 
  bars 
  in 
  smaller 
  specimens 
  and 
  3 
  in 
  the 
  larger 
  

   ones 
  ; 
  pectoral 
  fin 
  with 
  about 
  3 
  to 
  5 
  barely 
  discernible 
  vertical 
  bars 
  on 
  

   one 
  adult 
  specimen, 
  fins 
  of 
  other 
  specimens 
  completely 
  clear; 
  pelvic 
  

   fin 
  with 
  a 
  faint 
  brownish 
  blotch 
  or 
  bar 
  in 
  specimens 
  about 
  50 
  mm. 
  in 
  

   length, 
  fins 
  of 
  largest 
  specimens 
  clear; 
  anal 
  fin 
  with 
  a 
  faint 
  dusky 
  bar 
  

   in 
  smaller 
  specimens, 
  completely 
  clear 
  in 
  larger 
  specimens; 
  caudal 
  

   fin 
  with 
  2 
  to 
  7 
  oblique, 
  dusky-to-brown 
  bars 
  on 
  each 
  lobe, 
  the 
  bars 
  

   increasing 
  in 
  number 
  with 
  increase 
  in 
  length 
  (table 
  3) 
  ; 
  the 
  bars 
  on 
  the 
  

   lower 
  lobe 
  broader, 
  wider 
  than 
  the 
  clear 
  interspaces, 
  and 
  more 
  in- 
  

   tensely 
  developed 
  than 
  those 
  of 
  the 
  upper 
  lobe; 
  bars 
  on 
  upper 
  lobe 
  

   almost 
  as 
  wide 
  as 
  clear 
  interspaces; 
  bars 
  on 
  fins 
  in 
  varying 
  degrees 
  

   of 
  intensity, 
  the 
  caudal 
  bars 
  being 
  most 
  evident. 
  

  

  Geographical 
  distribution. 
  — 
  East 
  Indies 
  (Scale, 
  1910; 
  Herre 
  and 
  

   Montalban, 
  1928) 
  and 
  Philippine 
  Islands. 
  

  

  Remarks. 
  — 
  The 
  differences 
  m 
  the 
  color 
  pattern 
  between 
  Fowler's 
  

   illustration 
  (1933, 
  fig. 
  28) 
  and 
  that 
  of 
  Herre 
  and 
  Montalban 
  (1928, 
  

   pi. 
  1, 
  fig. 
  1) 
  are 
  undoubtedly 
  associated 
  with 
  the 
  state 
  of 
  preservation 
  

   and 
  the 
  sizes 
  of 
  specimens 
  used 
  for 
  the 
  illustrations. 
  Fowler 
  indi- 
  

   cated 
  his 
  specimen 
  was 
  a 
  "young" 
  one. 
  The 
  low 
  number 
  of 
  caudal 
  

   bars, 
  fairly 
  conspicuous 
  bars 
  on 
  the 
  dorsal 
  fins, 
  and 
  well-developed 
  

   saddles, 
  as 
  he 
  has 
  illustrated, 
  are 
  characteristic 
  of 
  the 
  smaller 
  sizes. 
  

   Herre 
  and 
  Montalban 
  illustrate 
  about 
  7 
  bars 
  on 
  each 
  lobe 
  of 
  the 
  caudal, 
  

   which 
  is 
  characteristic 
  of 
  specimens 
  about 
  100 
  mm. 
  in 
  length 
  (table 
  3).
