  armed 
  with 
  numerous 
  series 
  of 
  minute, 
  rasp-like 
  teeth 
  ; 
  the 
  

   band 
  in 
  the 
  inter-maxillary 
  is 
  narrow, 
  that 
  of 
  the 
  superior 
  

   maxillary 
  is 
  rather 
  broader, 
  and 
  extends 
  on 
  the 
  outer 
  as 
  well 
  

   as 
  the 
  inner 
  margin 
  of 
  the 
  bone 
  ; 
  the 
  band 
  of 
  the 
  lower 
  jaw 
  

   is 
  narrow 
  behind, 
  and 
  broad 
  before 
  ; 
  the 
  vomer, 
  the 
  palate 
  

   the 
  sphenoidal, 
  and 
  the 
  pharyngeal 
  bones 
  are 
  all 
  furnished 
  

   with 
  similar 
  minute 
  teeth 
  ; 
  even 
  the 
  anterior 
  margin 
  of 
  the 
  

   branchial 
  arches 
  is 
  rough 
  with 
  minute 
  asperities. 
  The 
  tongue 
  

   is 
  short, 
  round 
  in 
  front, 
  and 
  rough 
  on 
  its 
  posterior 
  part 
  with 
  

   minute 
  teeth. 
  The 
  dorsal 
  tin 
  is 
  single, 
  semi-falcate, 
  near 
  the 
  

   middle 
  of 
  the 
  back 
  ; 
  the 
  first 
  ray 
  is 
  very 
  short, 
  the 
  4th, 
  5th 
  

   and 
  6th 
  longest 
  ; 
  they 
  are 
  placed 
  in 
  a 
  scaly 
  sheath 
  of 
  the 
  

   integuments, 
  which 
  ascends 
  for 
  some 
  distance, 
  but 
  without 
  

   any 
  adhesiou. 
  The 
  pectoral 
  begins 
  under 
  and 
  in 
  front 
  of 
  the 
  

   termination 
  of 
  the 
  opercle, 
  with 
  an 
  elongated 
  scale 
  in 
  the 
  

   axilla 
  above. 
  The 
  ventral 
  is 
  stout, 
  and 
  arises 
  rather 
  before 
  

   the 
  origin 
  of 
  the 
  dorsal 
  ; 
  it 
  has 
  a 
  supplementary 
  plate 
  above 
  

   the 
  rays, 
  three-fourths 
  as 
  long 
  as 
  the 
  fin 
  itself, 
  and 
  covered 
  

   with 
  scales. 
  The 
  anal 
  is 
  short, 
  sub-falciform. 
  All 
  have 
  their 
  

   roots 
  in 
  a 
  sheet, 
  like 
  those 
  of 
  the 
  dorsal 
  fiu. 
  The 
  caudal 
  is 
  

   long, 
  deeply 
  forked, 
  with 
  a 
  lanceolate 
  flattened 
  scale 
  both 
  

   above 
  and 
  below 
  its 
  root. 
  The 
  scales 
  are 
  but 
  slightly 
  

   adherent 
  and 
  exceedingly 
  thin. 
  The 
  lateral 
  line 
  at 
  its 
  anterior 
  

   part 
  is 
  straight, 
  and 
  runs 
  nearly 
  along 
  the 
  upper 
  third 
  of 
  

   the 
  body, 
  but 
  it 
  descends 
  to 
  the 
  median 
  plane 
  between 
  the 
  

   pectoral 
  and 
  ventral 
  fins. 
  The 
  head 
  is 
  pale 
  green 
  above, 
  

   and 
  white 
  with 
  often 
  a 
  roseate 
  tint 
  at 
  the 
  sides 
  ; 
  the 
  body 
  is 
  

   pale 
  silver-gray 
  above, 
  or 
  with 
  a 
  faint 
  greenish 
  tint, 
  and 
  

   silvery 
  at 
  the 
  sides 
  and 
  bell}-. 
  The 
  pupil 
  is 
  deep 
  blue, 
  and 
  

   the 
  iris 
  silvery.
