  very 
  largo 
  specimen 
  of

  fish 
  was 
  caught 
  in 
  the 
  

   southern 
  part 
  of

  a 
  voracious 
  animal, 
  

   that 
  feeds

  flesh, 
  both 
  lacking 
  firmness 
  

   aud 
  flavor,

  This 
  largest 
  of 
  all 
  the 
  Ilerriugs 
  has 
  a 
  compressed, 
  oblong 
  

   body, 
  with 
  a 
  flat 
  ubdomeu. 
  The 
  snout 
  is 
  obtusely 
  conical 
  ; 
  

   the 
  mouth 
  anterior, 
  lower 
  jaw 
  prominent. 
  The 
  iutermaxillary 
  

   is 
  .short, 
  the 
  maxillary 
  forms 
  the 
  lateral 
  part 
  of 
  the 
  mouth, 
  

   and 
  extends 
  beyond 
  the 
  orbit. 
  Between 
  the 
  mandibles 
  is 
  a 
  

   narrow 
  osseus 
  lamella, 
  attached 
  to 
  the 
  mandibulary 
  symphy- 
  

   sis. 
  Tlje 
  mouth 
  is 
  furnished 
  with 
  three 
  bands 
  of 
  viJliform 
  

   teeth 
  in 
  the 
  jaws, 
  with 
  teeth 
  on 
  the 
  vomer, 
  palatine 
  and 
  

   pterygoid 
  bones, 
  on 
  the 
  tongue 
  and 
  on 
  the 
  base 
  of 
  the 
  skull. 
  

   The 
  gill-membranes 
  are 
  entirely 
  separate, 
  Mith 
  numerous 
  

   branchiostegals. 
  The 
  scales 
  are 
  very 
  large 
  and 
  adherent. 
  

   The 
  lateral 
  line 
  is 
  distinct, 
  and 
  runs 
  in 
  an 
  almost 
  straight 
  

   line 
  along 
  the 
  upper 
  third 
  of 
  the 
  body. 
  The 
  ventral 
  fin 
  is 
  

   conspicuously 
  in 
  advance 
  of 
  the 
  origin 
  of 
  the 
  dorsal 
  fin 
  ; 
  the 
  

   anal 
  is 
  rather 
  longer 
  than 
  the 
  dorsal. 
  The 
  long 
  ray, 
  the 
  last 
  

   of 
  the 
  dorsal 
  fin, 
  forms 
  a 
  very 
  conspicuous 
  character 
  of 
  this 
  

   fish. 
  The 
  general 
  color 
  is 
  beautiful 
  silvery, 
  darker 
  on 
  the 
  

   back.
