  a 
  rather 
  wide 
  

   band

  of 
  origin 
  of 
  anal,

  origin 
  of 
  dorsal 
  farther 
  for- 
  

   ward 
  than 
  in 
  S. 
  canina; 
  stomach 
  much 
  distended, 
  filled 
  with 
  the

  fish. 
  

  

  Doreal 
  and 
  anal 
  continuous 
  with 
  the 
  caudal; 
  origin 
  of 
  dorsal 
  from 
  

   tip 
  of 
  snout 
  5.02 
  in

  dorsal 
  rays 
  shorter 
  and 
  weaker 
  than 
  

   those 
  of 
  the 
  anal;

  a 
  slender 
  

   filament, 
  one-third 
  the

  broad, 
  the 
  median

  1.33 
  times 
  length 
  of 
  head. 
  (In 
  our 
  example 
  of 
  S. 
  canina 
  the 
  

   pectoral 
  is 
  also 
  much 
  longer 
  than 
  head; 
  in 
  the 
  type 
  the 
  pectoral 
  is 
  

   said 
  to 
  be 
  equal 
  to 
  head, 
  but 
  the 
  rays 
  are 
  now 
  broken, 
  and 
  their 
  

   length 
  can 
  not 
  be 
  determined.)
