  — 
  Head 
  and 
  body 
  light 
  tan, 
  darker 
  tan 
  above 
  and 
  

   ligher 
  below; 
  a 
  brown, 
  horizontal 
  stripe, 
  its 
  width 
  about 
  one-half 
  

   diameter 
  of 
  eye 
  extends 
  from 
  junction 
  of 
  gUl 
  opening 
  with 
  body 
  to 
  

   area 
  just 
  above 
  midbase 
  of 
  caudal 
  fin; 
  a 
  dark 
  brown 
  saddle 
  on 
  caudal 
  

   peduncle 
  just 
  posterior 
  to 
  soft 
  dorsal 
  fin, 
  its 
  width 
  equals 
  least 
  depth 
  

   of 
  peduncle 
  and 
  extends 
  ventrally 
  to 
  lateral 
  line; 
  traces 
  of 
  brown 
  color 
  

   pattern 
  indicating 
  that 
  probably 
  two 
  more 
  saddles 
  existed 
  through 
  

   soft 
  dorsal 
  and 
  spiny 
  dorsal 
  fins; 
  a 
  small, 
  dark 
  spot 
  at 
  origin 
  of 
  spiny 
  

   dorsal 
  and 
  soft 
  dorsal 
  fins 
  and 
  one 
  dorsally 
  on 
  peduncle, 
  at 
  first 
  pro- 
  

   current 
  caudal 
  ray; 
  head 
  and 
  body 
  dorsally 
  above 
  lateral 
  line 
  with 
  a 
  

   "salt 
  and 
  pepper" 
  coloration. 
  

  

  Spiny 
  dorsal 
  fin 
  with 
  4 
  rows 
  of 
  faint 
  tan 
  spots 
  forming 
  horizontal 
  

   bars; 
  soft 
  dorsal 
  with 
  3 
  narrow, 
  brown, 
  horizontal 
  bars; 
  pelvic 
  fins 
  

   with 
  traces 
  of 
  3 
  or 
  4 
  bars; 
  caudal 
  fin 
  with 
  3 
  narrow, 
  oblique 
  brown 
  

   bars 
  on 
  upper 
  lobe, 
  the 
  clear 
  interspaces 
  more 
  than 
  twice 
  width 
  of 
  

   bar; 
  lower 
  lobe 
  with 
  6 
  or 
  7 
  brown 
  oblique 
  bars, 
  more 
  or 
  less 
  spotlike 
  

   and 
  not 
  on 
  the 
  two 
  outermost 
  developed 
  rays 
  (lower 
  lobe 
  on 
  USNM 
  

   154661 
  malformed 
  and 
  small) 
  ; 
  areas 
  on 
  caudal 
  fin 
  just 
  above 
  and 
  below 
  

   base 
  with 
  a 
  fine, 
  brownish 
  spot; 
  pectoral 
  and 
  anal 
  fins 
  transparent. 
  

  

  Named 
  asymmetricus 
  in 
  reference 
  to 
  the 
  unusually 
  reduced 
  number 
  

   of 
  oblique 
  bars 
  on 
  the 
  upper 
  lobe 
  of 
  the 
  caudal 
  fin. 
  

  

  Geographical 
  distribution. 
  — 
  At 
  present, 
  only 
  known 
  by 
  the 
  type 
  

   specimens 
  listed 
  above 
  from 
  the 
  Philippine 
  Islands. 
  

  

  Remarks. 
  — 
  The 
  number 
  of 
  oblique 
  caudal 
  bars, 
  more 
  than 
  twice 
  

   as 
  many 
  on 
  the 
  lower 
  lobe 
  as 
  on 
  the 
  upper, 
  and 
  their 
  narrow 
  width 
  

   coupled 
  with 
  the 
  absence 
  of 
  the 
  small 
  first 
  dorsal 
  spine, 
  low 
  number 
  

   of 
  pectoral 
  rays, 
  low 
  vertical 
  scale 
  row 
  count, 
  dark 
  lateral 
  stripe,
